Need a break from mountains, wine and cheese? The CERN lab near Geneva, like many other research facilities, offers tours of the premises. Photo courtesy of Flickr user mayhem.

They may be at work pursuing the greatest mysteries of the physical world—yet the men and women who operate the world’s most prestigious physics and astronomy laboratories aren’t necessarily too busy to host guests. Throughout the world, physics and astronomy labs—many of them shimmering like stars in the wake of tremendous discoveries and achievements, some on mountaintops, others underground—welcome visitors to tour the premises, see the equipment, look through the telescopes and ponder just why they almost always make you wear a hardhat.

CERN. It’s the little things in life that really matter to the researchers at CERN, or the European Organization for Nuclear Research. This facility—located near Geneva, Switzerland—has gained superstardom over the last year, after announcing the discovery of what had been a holy grail of physics for decades—sometimes called the “God particle.” First predicted by physicist Peter Higgs in 1964, the then-theoretical particle, which pops from a field that is believed to give other particles their mass—became known as the Higgs boson before more recently assuming its grandiose nickname. CERN’s $10 billion atom smasher, called the Large Hadron Collider, had been at work for several years in its subterranean home in the Alps, beneath the French-Swiss border, colliding protons at high speeds before rendering what seemed to be evidence for the God particle in 2012. After a year of analyzing data, CERN researchers officially announced in March that it was all but certain: They’d captured a handful of real, honest-to-God Higgs bosons (visible only via a peak on a graph of data). Should you be in the charming Swiss countryside this summer, consider taking a guided tour of this most distinguished of the world’s great physics laboratories.

Did you know? CERN’s researchers helped develop the World Wide Web as a way to share data among scientists.

Gran Sasso National Laboratory. Bundle up, say goodbye to the Italian sun and take a tour of the austere bowels of one of the largest underground laboratories in the world. The Gran Sasso National Laboratory welcomes visitors, who get to see some of the world’s finest physicists in action as they work on a variety of experiments. The laboratory is located thousands of feet below ground, beside a freeway tunnel within Gran Sasso e Monti della Laga National Park, and as wolves, deer and foxes in the wild country above chase and gobble each other up in their timeless ways, scientists in the Gran Sasso lab are busy pursuing the puzzles of neutrino physics, supernovas and dark matter. As part of an ongoing joint project, the Gran Sasso lab receives neutrino beams fired from the CERN lab, some 500 miles away. By observing a pattern of oscillations in such beams, protected from interfering particles by rock and water, scientists have been able to prove that neutrinos do have mass. (Still wearing that hardhat, I hope?)

W. M. Keck Observatory. Some of the largest telescopes on Earth stand on the summit of Mauna Kea, the 13,800-foot volcano on the Big Island of Hawaii. These instruments—about eight stories tall and weighing 300 tons each—have allowed researchers to pursue the most vexing of the universe’s questions: How do solar systems form? How fast is the universe expanding? What is its fate? Visitors age 16 and older can tour the site at a fee of $192. The tours last a marathon eight hours and include transportation, dinner, hot drinks and hooded parkas—which few tourists ever even think of packing along to Hawaii. WARNING: The high altitude of the site can pose pressure-related health hazards, and SCUBA divers should not visit the Keck Observatory shortly after any significant time spent underwater.

Sanford Underground Research Facility. A century and a half ago, who could have known that beneath the lawless land of the Black Hills would one day be one of the world’s most sophisticated physics labs? The Sanford Underground Research Facility is located in the old Homestake Gold Mine in South Dakota, reaching 4,850 feet below ground. Like other subterranean particle observation labs, Sanford’s Homestake facility relies on the Earth itself to eliminate radiation and associated nuisances from the environment and allow scientists to conduct their experiments free of cosmic noise and interference. The Sanford laboratory’s focal points include the origin of matter, the properties of neutrinos and the ubiquitous pursuit of dark matter, which makes up a majority of the mass in the universe but which physicists have yet to positively identify. Tours of the Homestake site are available. Visitors must first stop at the reception center on Summit Street in the adjacent town of Lead, open weekdays from 7 a.m. to 4 p.m. Once on the Sanford premises, they can neither smoke nor drive more than 10 miles per hour.

Laser Interferometer Gravitational-Wave Observatory. Even the world’s brainiest thinkers won’t think you’re lazy if you call it “LIGO.” This project consists of two sites roughly 2,000 miles apart—the distance being an essential component of LIGO’s research. The facilities are designed to detect gravitational waves, ripples in the very fabric of spacetime that are generated by cataclysmic events. Albert Einstein predicted their existence as part of his theory of general relativity in 1916. LIGO’s technology could detect these vibrations. To be certain that the sensors—contained in 2.5-mile-long vacuum tunnels—aren’t simply picking up the tremblings of local earthquakes, LIGO uses two locations distant from each other. One is in Hanford, Washington, the other in Livingston, Louisiana. Public tours of the Livingston LIGO site are scheduled about once per month and custom tours can be requested. To visit the Hanford site, call ahead.

Is there anybody out there? The instruments of the SETI Institute’s Allen Telescope Array stand poised to detect the sounds of alien life. Visitors to the area, located beside Mount Lassen Volcanic National Park, in California, may take self-guided tours of the facility. Photo courtesy of Flickr user Slideshow Bruce.

SETI Institute. It was founded in Mountain View, California, in 1984, and since then, well, this alien-hunting institute hasn’t really discovered what it has been looking for. Not that scientists with the Search for Extraterrestrial Intelligence Institute aren’t trying. The SETI Institute uses the Allen Telescope Array, near Mount Lassen, to listen closely to the sounds of the stars, hoping to receive signals that might indicate the presence of other intelligent beings in the universe. Let’s just hope they’re a little less intelligent than we are. After all, some scientists have voiced concerns about what will happen if humans actually succeed in making contact with an alien species. In 2011, researchers at Penn State and NASA jointly released a report in which scientists warned that aliens might enslave, kill or eat us. Undaunted by what fate may befall us—and in spite of recent budget constraints—the SETI Institute continues its search for extraterrestrial intelligence. The Allen Telescope Array is located at the Hat Creek Radio Observatory. Here, the heavily forested location makes for a quiet and scenic getaway. The riffles of Hat Creek are famed for their wild trout, while frequently clear night skies make for fine tent-free summertime camping in the nearby Lassen Volcanic National Park. Visitors to the Hat Creek Observatory can take self-guided tours.

Lick Observatory. Perched upon the 4,200-foot Mount Hamilton, near San Jose, California, the Lick Observatory is where astronomer Geoff Marcy of UC Berkeley, along with several colleagues, has helped identify hundreds of planets outside our own solar system since 1995, when scientists discovered the first such planet orbiting a sun-like star.* It was a pair of Europeans—Michel Mayor and Didier Queloz, using the Haute-Provence Observatory—who first looked closely at the sun-like 51 Pegasi, located about 50 light-years away in the Pegasus constellation. In this star they observed an oscillating wobble—a telltale sign of an orbiting planet. They published their discovery in October 1995. A week later, Marcy took a second look at 51 Pegasi and confirmed the planet’s discovery. The planet became known as 51 Pegasi b. Marcy and his colleagues went on to discover hundreds more planets. For visitors, Lick Observatory is almost as friendly as a public museum. The site—at which James Lick lies buried beneath one of the telescopes—is open most days of the year and includes a bed and breakfast. Musical performances, weddings and other events are held on the summit. Check out Lick Observatory’s website for more information about visits.

* In 1992, astronomers Aleksander Wolszczan and Dale Frail discovered the very first extrasolar planets—though these were orbiting PSR B1257+12, believed to be the stellar corpse of a supernova. Thus, the planets are considered extremely unlikely to bear evidence of alien life.

Lake Quilotoa is gaining a reputation as one of the most attractive destinations in Ecuador. The surrounding area, of rugged mountains and dirt roads, offers some of the most rewarding cycle touring in the Andes. Photo by Alastair Bland.

Ecuador has done a tremendous job of preserving its wild places. More than 20 percent of the country is protected within more than 30 parks and reserves, some of them quite vast. In a nation as compact as Ecuador, what this translates into for travelers is beautiful national parks, one after another, like stepping stones through some of the world’s most astounding scenery.

In the Andes, many of the giant volcanoes have their own namesake national park, and from south to north one finds Sangay, Chimborazo, Llanganates, Iliniza, Cotopaxi, Antisana and Cayambe-Coca, to name several. These protected areas essentially demarcate what is known as the Avenue of the Volcanoes, or Volcano Alley—and it’s this route that I followed on my final march northward, toward Quito and the finish line of the international airport.

Here, my adventure finally came alive. I had spent weeks floundering—either resting my injured Achilles tendon or, later, undergoing anti-rabies treatment at a hospital following an unpleasant dog encounter. During this time, I often lay in bed, read books, iced my heel and wished for the freedom of the hills. But I finally fell into the familiar rhythm of bicycle touring as I pedaled uphill from Puyo to Baños, a 3,500-foot climb that leads from the Amazon basin to one of the most esteemed tourist towns in Ecuador—and, even better, to the foot of Tungurahua, the three-mile-high mountain that has been spewing smoke and ash for several months. Like most of the peaks along Volcano Alley at this time of year, Tungurahua hid within a ceiling of clouds, and I only caught a glimpse of the triangular peak one night in the light of the half moon when I peeked out my tent.

The scenery that unfolds behind as one climbs the road to Llanganates National Park makes the effort, and the frigid wind, worth it. Photo by Alastair Bland.

Though the Panamerican Highway bisects the Avenue of the Volcanoes, contriving routes to avoid this congested, smoggy artery brings one, as a matter of course, into some of the finest hiking, cycling and adventuring country anywhere. The land is hilly and green, and in places rugged and dangerous. I spent one afternoon ascending from the town of Pillaro into Llanganates National Park, home to the 10,792-foot Cerro Hermoso and, at the end of the long and difficult road, Laguna Pisayambo. The asphalt turns to dirt as the road steepens near the park entrance. The wind wails here, across treeless slopes, and cyclists and backpackers will find a cozy surprise—a refuge free for public use at the park entrance, at nearly 13,000 feet. I arrived at dusk, and two employees welcomed me, fed me and offered me the use of the hot water, the stove and a bed. But I chose to camp outside, and as the cold night came on, the lights of the city of Ambato 4,000 feet below flickered and shined like a million stars. Hidden in the darkness across the valley was Chimborazo’s 20,564-foot summit—often advertised as “the closest point to the Sun”—but I couldn’t see it, and never did, for it remained buried in clouds.

The cold, dry mountains southwest of Quito, in the region of Lake Quilotoa, are some of the most beautiful anywhere, and among the most popular cycling regions in Ecuador . Photo by Alastair Bland.

The next day I crossed the Panamerican Highway and headed west, for the much-loved but little-known Quilotoa-Sigchos basin, where I would spend a week exploring what might be the best cycling region in Ecuador. Right out of the town of Latacunga, the road goes up. To non-cyclists, this may sound like the worst of possibilities, but for me and many of my fellow cyclists, climbing is the reason we own bicycles at all. It’s on those uphill grades that we feel the heat of our own blood and the pace of our hearts. Climbing, perhaps, reminds us we’re alive, while million-dollar views take shape behind us. The road out of Latacunga ascends to some 13,000 feet before leveling off on a broad plateau of Andean tundra, then descends into a beautiful valley peppered with farmhouses and tiny villages, and a camping site called Posada de La Tigua. Here, the owners may try and talk you into taking a room for $35. Just camp. It’s $3.50, and you can watch the stars of the southern sky.

Onward, and the dramatic ups and downs, the friendly people, and the green hills make smiling out here as natural as breathing. In Zumbahua, a pair of video-journalists with a Quito-based cycling club, BiciEcuador, interviewed me and asked how I liked this area.

“The best of Ecuador,” I said.

The pride and joy of this region is Lake Quilotoa. There is an adjacent town of the same name—a little community of indigenous people fortunate enough to be located on the edge of a dramatic crater. Here, travelers find a vista that makes the jaw drop and clunk against the sternum. Lake Quilotoa lies almost 2,000 feet below, and from these heights one can see the wind ripping the jade-green surface. Hikers popularly walk around the crater’s rim and may follow a trail down to the water’s edge. Here, some people camp, and I saw tents pitched on a beach straight below me. The quiet, dusty village of Quilotoa will probably become either one of the hottest, or one of the most underrated, tourist destinations in Ecuador. But in February it is a strange place. It is the slow season, and there are more hostels than tourists. Nearly every building, in fact, is a hostel—perhaps 15 of them—and more are being built. The town is clearly still developing its tourist infrastructure, for among all the hostels, and even in the large visitor’s center, there is no internet—no WiFi, and no plug-in connections. Several other establishments in Quilotoa, meanwhile, sell artisanal crafts and woven items of alpaca wool. Chilly gusts of wind sweep through the quiet streets and remind one that the elevation here is almost 13,000 feet. A pair of locally made alpaca gloves for $5 are a worthy buy.

Travelers who continue north from Quilotoa will find a downhill run to the friendly little village of Chugchilan, set on the slope of a steep and forested canyon. I took note of several hostels here, then continued through the village and took a side road uphill, following signs to a nearby cheese factory about 2,000 feet straight up, on a foggy mountaintop. The sign at the gate advertises the fact that this little operation uses Swiss technology. What? Flavorless Andean queso fresco isn’t good enough? (I actually quite enjoy the local mountain cheese.) I took away a pound of mozzarella and continued on a scenic loop that would bring me back to the village. “Did you manage to find the cheese factory?” a rusty red-faced man with a wide smile and a huge machete asked me. I had never seen him before, but he knew why I was here. He spoke with a strange accent, for he was among many folks here whose native language is the indigenous Quechua.

The people in these mountains were some of the politest I’ve ever met. Turkish hospitality is famous but can be overwhelming with insistent offers of tea and food. In the Andes, it’s all smiles and hellos and respectful distances. The children, especially, are marvels of manners and courtesy. They almost never fail to call out a friendly greeting, and they have several times proven incredibly articulate and thoughtful in helping me find my way through a complicated road network to my destination.

“It is 40 kilometers to Isinlivi,” a boy said to me one afternoon on a dirt road circling through the high hills. “On a bicycle, that means you’ll be arriving after dark. You must find a place to camp before then.” He was no more than 8 years old.

I stayed in Chugchilan at the Cloud Forest Hostel (reviewed here by Globe Trotter). They offered dinner of fried plantains, chicken and rice, but I cooked quinoa and eggs in my room and studied my map, mesmerized by its language of dots, lines and triangles. There were so many route options, so many villages, so many valleys—so much to see. I was only 60 kilometers from Quito as the condor flies, but I saw that I could have spent weeks traveling the dirt roads that crisscrossed this tiny region. I had only a week left, however. Where would I go? Was there time?

Ecuador may seem little, but it’s bigger even than the imagination.

The beauty of Vilcabamba and the Valley of Longevity has entranced many, inspired legends and attracted eccentrics, but the town may not quite live up to the lore. Photo courtesy of Flickr user johnrodgers.

In the Valley of Longevity, in southern Ecuador, visitors find the quiet and legendary town that has inspired travelers for decades—Vilcabamba. Once just another of a thousand beautiful Andean villages, this community of about 4,000 people is today one of the hottest destinations for outsiders seeking their own little piece of Shangri-La. The town, of affordable goods and productive soils, promises new life—not to mention long life—for both vacationers and expats, and in the past two decades Vilcabamba has become an uncanny magnet and New Age watering hole for soul-searchers dabbling in everything from agriculture to shamanism to hallucinogens.

But as one nears the village center along a cobblestone road that diverges from the highway, the legendary Vilcabamba seems too quiet for its reputation. Dozens of people sit idly in the square—well-to-do tourists, hippies with dreadlocks and bead necklaces, a few locals, men with week-old scruff and worn sandals—all of them waiting, it seems, for things to happen. As I cycled into the plaza, a friend of mine from Cuenca, Mick Hennessey, from Utah, was seated on a plaza bench, alertly watching the slow activity. He saw me and waved. “There’s nothing much going on here,” he said, seemingly reluctant to make such a decree so early. He had arrived only three hours before me by bus. “Sure is pretty up there, though,” I said, pointing at the mountain ridges surrounding this Valley of Longevity, so named for its supposedly high concentration of centenarians.

Another tourist, Nathan Resnick—an American currently living in Cuenca—spent several days in Cuenca hiking in the hills between nights at the Rendezvous guesthouse. He was glad with what he found.

“I was expecting a lot more and was pleasantly surprised that it didn’t exist,” Resnick said.

The town is surrounded by fantastic green ridges on the skyline and lush woods that make a paradise for backpackers, botanists and bird watchers. It is also the last chance for food and gear before entering Podocarpus National Park just to the east—home to bears and wild cats and countless bird species.

But according to some locals, Vilcabamba is unable to meet the needs or hopes of many who visit each year.

“People come here to solve their problems, but they never actually leave anything behind and so they bring all their baggage with them,” one man—a Canadian who has lived in Vilcabamba part time for a decade—told me about a block from the plaza, after we met and shook hands in the empty street. And so, he went on, health problems and mental maladies accumulate here with the immigrants. In particular, he said, conspiracy theories and UFO reports saturate local gossip. This interview by Uncornered Market of a resident Vilcabamban reads almost like a transcript of our conversation.

I quickly detected a very dark shadow hanging over the town. Only three days earlier, a woman had been raped on a trail in the woods just northeast of the town—the third such incident in just weeks. The alleged assailant was reportedly still at large. This January 25 blog post on Passionfruitcowgirl describes a dramatic attempted rape in what the author calls “Evilcabamba.” Another blog, Patryantravels, published a post last August titled “Paradise Lost,” which dwells on the steady rising tide of crime, both petty theft and physical assaults, that have damaged the pretty face of Vilcabamba. Among these recent events is the dramatic kidnapping for ransom that occurred in September on a nearby mountain trail, where a honeymooning couple was assaulted by three armed men wearing masks. The man was ordered to return to the town, retrieve several thousand dollars and deliver it back to the bandits, who said they would otherwise kill his wife. The couple survived the encounter—though the town’s reputation has taken a blow, and attentive eavesdroppers here can pick up on conversations in every direction about robbery, rape and the absence of the police.

Even as long ago as the 1970s, things seemed too good to be true in Vilcabamba. National Geographic, among other publications, had reported an unusually high number of centenarians in the village, but Dr. Alexander Leaf, of Harvard Medical School, was growing skeptical of villagers’ claims to be well over 100—and in one case as old as 134. He called upon two American professors to come help determine the truth. They did, and in 1978, after pressing villagers for information and facts, Richard Mazess of the University of Wisconsin and Sylvia Forman of U.C. Berkeley released their findings. The entire legend of long life was no better than myth—and as bad as outright lies. There was not, they reported, a single person over 100 in the Valley of Longevity. The average age of supposed centenarians was actually 86 years old, and one man who claimed to be 127 years old in 1974 was actually 91 at the time.

The columnar San Pedro cactus (not to be mistaken with the adjacent prickly pear cactus with the paddle-shaped limbs) can be rendered into a hallucinogen commonly consumed in South America as a liquid. The plant, native to the Andes, draws its share of tourists to places like Vilcabamba, where shamans prepare and serve the drug. Photo courtesy of Flickr user Micah & Erin.

The blur between fact and fiction in Vilcabamba may—or may not—have something to do with a local hallucinogen called aguacolla, made from mescaline extracted from several dozen species of cacti in the genus Trichocereus, collectively referred to as the San Pedro cactus. T. pachanoi is the most commonly used for medicine and (let’s be honest) sport. Shamans and village doctors have used the cactus for ages, and the drug today, though illegal in many countries, is provided by licensed shamans and in the Andes is a popular draw for tourists seeking the journey—trip, that is—of a lifetime.

“What was it like?” I asked an American man on the plaza who had partaken in a group experience the night before at $70 a head. He was waiting for a cab, planning to head back to the camp for anther go. “I’m still trying to figure it out,” he said, seemingly thrilled as he hoisted his suitcase to the curb and waved to a taxi. “All I know is there was a whole lot of vomiting.”

“That sounds amazing,” I said.

As the website for Sacred Medicine Journey, a local shaman service, advises its prospective participants, “You may feel some discomfort, but the benefits are worthwhile. Remember that this is not recreational.”

The floodgates to weirdness seem to have opened wide in the 1960s with the arrival of the late Johnny Lovewisdom and his followers. Lovewisdom was an off-kilter spiritual guru and leader who was drawn to Vilcabamba by the “longevity” legend. Born as John Wierlo, Lovewisdom practiced a variety of unusual lifestyle diets throughout his life. Among his lasting legacies was his advocacy of a raw, fruit-only diet, though he eventually allowed yogurt and other fermented items into his body. Lovewisdom, who reportedly struggled with a number of uncommon health problems, also advocated water-fasting, sun diets and breathanarianism, which holds that humans can subsist on spiritual energy alone.

“A woman told me in town to be careful here because there is so much negative ‘energy’ in the air,” laughed a young German man as we ate breakfast at the campground kitchen of Rumi Wilco Eco Lodge, the cheapest place in town at $3.50 for a tent site. He was leaving that day for Peru via the Zumba border crossing just 80 miles south. The man was a skeptic of the Vilcabamba lore, and unlike thousands before him, he was not seduced by the village’s call.

Though the continuing crime wave and growing insider disenchantment with Vilcabamba have darkened the village, the innocent weirdness introduced by Lovewisdom remains. One morning in the driving rain at Rumi Wilco, a tall and lanky Dutchman—a raw foods fruitarian, it happened—undressed to his underwear on the lawn between the kitchen and the guest cabins and began a bizarre and comical calisthenics routine, punctuated by clumsy overhead jabs of the arms and poorly postured yoga stretches. He finished his workout with several minutes of running ten-foot-wide circles through the mud—one more eccentric seeking grace and happiness in the Valley of Longevity.

The sky remained gray for several days, and if there were people here who really could subsist on sunshine, as the eccentric Lovewisdom believed possible, they were probably thinking about a sandwich. And if they believed everything that the local mythology promised, they would almost certainly die younger than they hoped to, in the beautiful little village of Vilcabamba.

Rod (left, holding child) and Ingrid (far right) McCarroll of Alberta, shown here in central Mexico, have traveled the world helping to bring a cheap and effective water filtration system to many thousands of people. Photo courtesy of Friends Who Care International.

Give a man a glass of water, and you may quench his thirst. But teach him to build a biosand water filter using local materials and the simplest technology, and he’ll have clean water for life at a cost of just $30.

Even better, Rod and Ingrid McCarroll, two retired Canadians, will pay half the cost or more if the 30 bucks is too steep. Sometimes it is. The McCarrolls, of Calgary, Alberta, have been traveling the world for 12 years in some of the most impoverished communities with the goal of bringing clean water to millions. They have worked through their own nonprofit organization, Friends Who Care International, in rural India, Mexico, Honduras and Guatemala. Last year, they spent six months in Nicaragua alone. Just two weeks ago, they arrived in Ecuador.

“We hope to provide clean water for 20 million people,” Rod told me at the Hostal El Taxo in Quito, where we met by chance in the dining room. “It’s estimated that 1.2 billion people now don’t have clean water for drinking or cooking. The problem is, the world is growing faster than we’re able to help.”

The biosand water filter that is the main feature of the McCarrolls’ work is a relatively simple thing. Invented in the 1990s by David Manz, an environmental engineering professor at the University of Calgary, the contraption is composed of carefully selected and treated sand and gravel, as well as a layer of iron nails, strategically layered in a four-foot-tall concrete casing. The setup weighs more than 200 pounds, making it too heavy to steal. Maintenance is easy, requiring simply scooping the mucky top water from the gravel layer every few months. Being too simple to experience serious mechanical breakdowns, the water filter all but guarantees a family clean water for life. Tap, pond or river water is poured into the gravel, and at a rate of one liter per 80 seconds, pure water emerges from the spout. The filter removes 99.5 percent of bacteria, viruses and protozoa, according to Rod, as well as 100 percent of parasites and 100 percent of arsenic—which bonds to the iron oxide molecules of the rusting nails and becomes unable to travel through the filter. Currently, the McCarrolls are in the rural mountainous regions surrounding Cuenca—Ecuador’s third-largest city—working with local contacts and community leaders to teach them how to build the filters. Arsenic, Rod says, contaminates much of the region’s water—a serious problem that could be solved as easily as the filter is simple.

Rod stresses that he and Ingrid are not just delivering clean water to one family at a time. Rather, they are teaching others—especially community leaders—to build biosand water filters and to teach the trick to others. By this means, the snowball effect seems already to have kicked in. While the McCarrolls have worked in just half a dozen countries, Rod says that clean water now trickles from half a million biosand water filters in 75 countries.

It hardly takes a village—just a few helping hands—to install a biosand water filter. Here, Rod McCarroll helps Nicaraguan villagers put the finishing touches on a contraption that will provide clean, pure water almost indefinitely. Photo courtesy of FWCI.

Apart from clean water, the McCarrolls have also worked to bring sustainable, off-the-grid electricity to the needy through another Canadian nonprofit called Light Up the World. Living in literal darkness, Rod says, means living in intellectual and spiritual darkness, too—as people cannot educate themselves if they return from work to a home too dim to read in.

But the McCarrolls have another objective, too, which leads them through more figurative realms of light and darkness: They are Christian missionaries. This is a more latent, secondary element of their work. Clean water and electricity come first, and religion follows. It may take 30 minutes of chatting with the pair even to discover their spiritual concerns, yet along with biosand water filters, they are indeed missionaries, encouraging those who accept their help to also adopt Christianity.

“If you go around the world and tell starving people that God loves them, it’s hogwash,” Ingrid said. “It means nothing. But if you give them something, then they see that they really do have friends.”

Rod says the interest in dispensing Christian ideals goes hand in hand with having clean water, electricity and basic sanitary conditions. He says, too, that religious conversion is not a main objective—but that it doesn’t hurt to make Hindus into Christians. The caste system, outlawed in India yet persisting through tradition, plagues much of the Hindu world—especially India. It relegates people born as untouchables to a life of poverty and filth—and with contaminated drinking water to boot, Rod points out.

“We’re just trying to help remove them from this darkness,” he explains. “But there are 600,000 villages in India, and many of them don’t want anything to do with missionaries. So how do we get in?”

The biosand water filter. Given to the needy and bearing with it the heavy scent of Christianity (the McCarrolls may prompt prayer circles with families before they depart), “the water filter,” Rod says, “serves as a 24/7 missionary.”

Rod is 71 years old. Ingrid is 70. When she was a child, she barely escaped from East Germany before the Berlin Wall went up. Her family had been torn apart during the turmoil of war, but they managed to reconvene with the help of the Red Cross in Austria in 1945. Ingrid and Rod met and married 46 years ago. Upon retiring, they determined not to kick up their feet between rounds of golf and luxury vacation cruises.

“We decided that we’d done well, and we wanted to give back,” Ingrid said.

After learning about Manz’s biosand water filter in the late 1990s and growing efforts to dispense the invention around the world, the McCarrolls saw their opportunity to help the world’s unfortunate. They worked at first with the organization CAWST (Centre for Affordable Water and Sanitation Technology), which was led by Camille Dow Baker, a former oil development executive striving to reform her career. Once the McCarrolls had learned the ropes, they established Friends Who Care International in 2001, and they have divided their time between Calgary and the wider world ever since.

About 15 miles north of Quito, a palatial iron gate on the west side of the highway opens onto a long, stately driveway leading across a prim and trim government property, past statues of acclaimed national leaders and, after about 200 yards, to the base of a nearly 100-foot-tall brick-and-mortar monument, grand enough to produce tears, called the Mitad del Mundo—“Middle of the World.” A yellow painted stripe representing the line of zero degrees latitude even runs up a walkway and bisects the monolith, which was built in 1979 and stands today as a premier tourist attraction, and a grand and glowing tribute to one of Ecuador’s proudest features: the Equator.

The problem is, they built the thing in the wrong place. The Equator is actually several hundred feet to the north, as determined by modern GPS technology that wasn’t available to the earlier surveyors of the region. As long ago as 1736 scientists were exploring Ecuador, with, among other goals, the aim of defining and marking the Equator. At some point, the current Mitad del Mundo line was painted proudly on the ground. But in recent decades, the embarrassing truth emerged: The Equator actually, and without a doubt, crosses the highway just up the road, where the property owners surely rejoiced upon hearing the news (and took their own GPS measurements, as they claim they have done) and have since built their own rather campy but perhaps more accurate attraction.

As for the grandiose government monument just to the south, what’s built is built, and, as the saying goes, no publicity is bad publicity. And so the yellow painted line that leads into the museum at the base of the Mitad monument is still declared to be the waistline of the Earth and draws hundreds of thousands of tourists every year. Here, they walk the line, straddle it, try and balance eggs on it and shake hands over it.

But I didn’t do any of those things. I didn’t enter the museum, either—not because admission was $3 but because I didn’t see the point. Nor did I see any point in getting coffee at the Equator, buying “Mitad del Mundo” trinkets at the gift shops on the Equator, eating lunch at the Equator, sitting down for a beer at the Equator or petting an alpaca at the Equator (the little camelids roam the premises). Because I wasn’t on the Equator and it all would have meant nothing. Carved into the monument is the site’s elevation (2,483 meters) and longitude (78 degrees, 27 minutes and eight seconds west—or so they say). But these somewhat arbitrary numbers are made even more so since, well, this isn’t the Equator.

Still, I did as many visitors to the Mitad do and had my passport stamped by the lady working the museum admission booth so that I could prove to the folks back home that I had actually stood on the Equator—well, almost.

“Does the stamp say ‘Mitad del Mundo, Mas o Menos’?” Alistair Hill joked minutes later, just after I met him and several other British travelers on the steps before the monument.

Hill and his girlfriend Jess Swan, both from England and now backpacking through South America for several months, gazed up at the hulking, majestic thing. They had heard the rumors that the attraction was not all it is claimed to be but made the trip from Quito anyway, splitting a cab four ways for $40.

“How did they get it so wrong?” Hill said. “Why didn’t they just flush a toilet on each side to make sure they had it right? It makes you wonder if the Meridian really passes through Greenwich.”

Hill’s friend Chris Leigh joked, “So, what else in the world have they got wrong? The South Pole? The North Pole? The Tropic of Capricorn? That’s probably 100 miles out of line. Turns your world upside-down, doesn’t it?”

But for all the pomp and circumstance, gravity and grandeur of the Mitad del Mundo, that a huge mistake has been made is freely admitted today, and the officials who work at the site readily tell visitors who inquire where to find the actual Equator.

“Turn left at the gate, and it’s 100 meters on your left,” the guard at the entrance told me as I was leaving.

The entrance to the site of the true Equator is modestly labeled—but with a subtle jab at the Ecuadorian government: “calculated with ‘GPS.’” Photo by Alastair Bland.

You have to watch closely, but you’ll see it—a sign reading “Museo Solar Inti-Nan.” The sign assures you that you are now at zero degrees, zero minutes and zero seconds—neither north nor south of the middle of the world. The sign adds that these figures were “calculated by ‘GPS.’” It comes off as a smirking insult directed at the government site just down the road, but the sign is only being honest. A humble dirt trail leads visitors up a ravine, across a small bridge and into the outdoor museum area. While guests are free to wander at the Mitad del Mundo site, at the private museum visitors are quickly asked for $4 and then ushered into a small tour group, whether you want the service or not. I joined Amy Jones of Texas and Stefania Egas of Quito, and our English-speaking guide led the way. Much of the tour, through wood huts and artifact collections, has nothing whatsoever to do with the Equator. We saw a pen full of guinea pigs, a shrunken human head, a soggy dead boa constrictor in formaldehyde, a collection of totem poles and an exhibit featuring native folks of the Amazon.

But we finally got to the feature attraction—the Equator. It is represented by a red line, along which have been mounted a sundial, a spinning globe, nail heads on which one may try and balance an egg and—the grand fireworks of the tour–a full wash basin used to demonstrate the way that draining water supposedly swirls in a particular direction in each hemisphere. There has been much debate about this phenomenon. The Coriolis effect, a function of motion and the curvature of the Earth, is real, a phenomenon by which free-moving objects in the Northern Hemisphere appear to veer toward the right and those in the Southern Hemisphere to the left. At zero degrees latitude, the effect does not occur. This is why, for example, hurricanes wither and dissipate when they drift too close to the Equator.

But whether toilets and sinks, at their small scale, can demonstrate the Coriolis effect isn’t clear, though most experts say that the Coriolis effect does not visibly affect moving water over such a short distance as the diameter of a sink or toilet. Yet our young mono-toned tour guide, drably repeating a show she had probably given many times before, made it happen. On the Equator, after she pulled the drain plug, the water shot straight through without a swirl in either direction. Ten feet to the south, the water drained in a clockwise gyre. And just to the north, the water went down in a counterclockwise whirlpool. I suspect there was trickery at play—possibly by a hand furtively dipped into the basin and slyly setting the appropriate flow direction when we weren’t watching. I walked away frustrated, if not wowed, and I admit: The 100-foot-tall monument of the government, though a big fat mistake, is a greater site to see.

But just when we think we’ve got the whole matter sorted out and the Earth perfectly bisected, I discover this blog post from a science-savvy traveler named Adam Rasheed, who claims we’ve all been duped twice over. In 2006, Rasheed wrote a blog entry for a science and technology firm called Global Research in which he described visiting both of the equatorial sites, being skeptical of the private museum’s claims of legitimacy and promptly taking equatorial matters into his own hands using a GPS device. Rasheed concluded that the true Equator was still farther up the road, and here he and a friend built their own equatorial monument of plastic drink bottles and rubbish. Whether Rasheed had it right seems, by now, doubtful—not that it really matters. Because if Ecuador builds the 5,000-foot-tall spire that a New York architect proposed be erected on the Equator, then that would be the destination most worth paying to see—whether they place it exactly at zero degrees latitude or not.

Perhaps there is only one thing certain in this foggy fuss over the Equator: The more monuments and museums the merrier. If you think you can improve upon the existing measurements, let us know in the comment box below.

The Equator museum’s white-knuckle grand finale—the wash basin demo: Here, the tub is being drained directly over the Equator, and the water rushes straight downward. Just five feet to the north or south, the Coriolis effect kicks in, leaving skeptical tourists wordless. Photo by Alastair Bland.
