Vientiane, Laos - During our honeymoon, my wife strapped herself to a steel cable, kissed me goodbye and threw herself off the side of a mountain. I watched as she disappeared into the jungle mist, leaving only her scream.
Then it was my turn.
I clipped my roller to the zip-line, took a running start and flew high above the canopy as the forest plummeted below. It felt like horizontal BASE jumping. The adrenaline rush turned into wide-eyed wonder as I burst through the fog and glided gently through the open window of a childhood fantasy: a towering three-story treehouse built 150 feet up in the branches of a mammoth strangler fig tree overlooking the rain forest.
“Welcome home,” said my smiling wife.
Were Tarzan to dream up an eco-tourism adventure, it would probably look a lot like the Gibbon Experience in northwest Laos. During a three-day, two-night journey, you're led deep into the remote jungle of the Bokeo Nature Reserve by guides from the surrounding hill tribes. After climbing up a series of twisting mountain trails, you “fly” over the rain forest on a heart-stopping network of zip-lines - some of which are suspended 500 feet above the forest floor and span more than six football fields. At the far end, you hike up again to continue crisscrossing the canopy on this sky-high superhighway.
At night, you sleep in some of the tallest treehouses in the world - thatched, open-air observatories surrounded by panoramic views of the forest and a symphony of birds. The only way in and out of your airborne abode is via zip-line: You run off a ridge in the forest and gain enough momentum to soar in on one line, then jump out and let gravity carry you on another. Women from nearby Hmong and Lamet villages fly in your fire-cooked meals each night. Every morning, you wake up, slide on a harness and essentially toss yourself out of a 15-story building.
Not only is this exhilarating adventure one of the most unforgettable experiences in Southeast Asia, it's also one of its most effective conservation concepts. As people from all over the planet swoop in to sleep and play high up in the trees, they're helping to protect a critically endangered primate: the Laotian black-crested gibbon.
Due to decades of deforestation and illegal hunting, this sprawling nature reserve between Burma (also known as Myanmar) and Thailand is home to one of the last remaining populations of this rare creature. In fact, the subspecies was long believed to be on the road to extinction when Jean-Francois Reumaux, a French teacher with a passion for forest preservation, travelled from the Laotian capital, Vientiane, to the Bokeo region about 20 years ago. He spent a month living in the jungle and climbing trees to search for the elusive animals.
“I finally got close enough to film them, and when I showed the footage to anthropologists in Europe, they didn't think it was real,” Reumaux told me over the phone. “So I told them they should come to the canopy and see the gibbons for themselves.”
Thus the idea for a sustainable monkey business was born.
Today, the project employs 142 canopy guides, cooks and treehouse builders. By offering villagers a more-lucrative alternative to poaching, logging and slash-and-burn farming, the organisation has turned some of the gibbons' former predators into their full-time protectors. The Gibbon Experience pays 25 armed forest guards - the only ones in Laos's national parks - to patrol the rain forest and protect it against poachers.
Reumaux says Bokeo's gibbon population has risen to its highest level in decades. Clouded leopards and Asiatic black bears are making a big comeback, too, he said.
I'm glad I didn't know that last detail as my wife and I began our adventure by bumping along dirt roads in the back of a pickup truck with five other backpackers. After a two-hour drive through the jungle from the Gibbon Experience's headquarters in Houayxay, we arrived at the Hmong hill tribe village of Ban Toup, where we met our guides, Phad and Si, who gave each of us a safety harness, zip-lining gloves and a warm Beerlao.
“It'll taste better in the treehouse,” Phad joked. Soon, we were off, but not before Phad's extended family came out of their thatched huts to hug him goodbye and see us off with shy smiles.
We hiked into the mountains and were quickly engulfed in a riot of twisting vines, studded palm leaves and massive banyan trees. Two hours and one banana-leaf-wrapped baguette lunch later, we couldn't climb any higher.
“Who wants to fly?” Phad asked.
My wife shot up her hand. After a crash course in how to zip - legs up, lean back and squeeze the strip of worn bicycle tire that serves as a brake - she was gone, tearing at 40 mph through the canopy and losing her baseball hat in the process.
Just as I strapped in and prepared for my first flight, Phad whispered one more helpful hint to me: “Don't look down.” It turns out that, despite five years of professionally soaring through the sky while dangling on a wire, Phad is absolutely terrified of heights.
“I always close my eyes,” he admitted. “But you should be okay!”
I was, until I shot a glance downward and caught sight of my tiny shadow racing across the treetops hundreds of feet below. I screamed as loudly as I could until I sailed safely into Si's arms on the far platform.
Ten 500-meter trust falls later, our group was perched in the branches of our nest for the night, each quietly admiring the architectural marvel. Never mind the rooftop solar panels, suspended bedroom balconies and sweeping 360-degree views, the highlight of our sky-high home was hidden behind a curtain in the bathroom: an open-air shower where cool rainwater shoots down from the ceiling, washes over you and then drains through wooden floor slats and falls 150 feet into the rain forest below.
It's hard to oversleep in the jungle, especially when your home sways ever so subtly in the breeze. Phad and Si swung in just after dawn to lead our droopy-eyed group through a series of bamboo-lined trails. When we landed back in the treehouse, breakfast was waiting for us in the living room. In addition to rice, stew and piping-hot coffee, there were fresh omelets made from the bag of eggs that Si had carried as he tore through the forest the previous day, never cracking a shell.
We whizzed across 11 more zip-lines on the second day - some more successfully than others. Whenever gravity left us dangling short of the far platform, we'd each have to turn around in midair to pull ourselves, arm over arm, toward land while the rest of the group cheered: “C'mon, monkey!”
If you go..
The Gibbon Experience
Th. Saykhong, Houayxay
The Gibbon Experience offers three options: The three-day, two-night Classic Experience ($310/RR4 000); the three-day, two-night Waterfall Experience ($310); and the two-day, one-night Express Trip ($190). All meals are included.
There are regular flights from the Laotian capital, Vientiane, to Houayxay on Lao Skyway. There are also “slow boats,” “long boats,” and “speed boats” that take passengers along the Mekong River to Houayxay from Luang Prabang and the Thai border town of Pak Beng - among them the Shompoo Cruise and Luang Say Cruise. In addition, there is regular Greenbus service from Chiang Mai and Chiang Rai (Thailand) to the Laos border, just over the Mekong River from Houayxay.
Bring sturdy hiking boots and long socks to deter leeches (especially in the wet season from May to September). Everything you carry will be in your backpack. We recommend bringing water, a camera, toilet paper, mosquito repellent, soap, a flashlight and - depending on how many nights you spend in the treehouses - clean clothing. Aside from solar-powered lights, there is no electricity in the treehouses, so be sure to charge your camera batteries beforehand. Towels, mosquito nets and bedding are provided.
Send an email to [email protected] with your preferred date, trip and the number of travelers. A representative will usually get back to you within 48 hours with details and availability. Prepayment is made online through PayPal.
Where to stay
The Gibbon Experience asks that participants check in at its office in Houayxay the day before their trip's departure. Therefore, most people end up spending the night in Houayxay. There are a number of modest guesthouses in town. Here are our favorites:
Located down the street from the Gibbon Experience, Sabaydee is a family-run spot with WiFi, air conditioning, private showers and a rooftop terrace that overlooks Houayxay's main drag.
Riverside Houayxay Hotel
R3A Rd., Ban Khonekeo
This is Houayxay's most upmarket option. The three-story building overlooks the Mekong River and is conveniently located next to the boat pier. Rooms have WiFi, air conditioning and private balconies.
Where to eat
Daauw is a restaurant and a bungalow that contributes proceeds to help empower minority women from the surrounding hill tribes. A great cause aside, the wood-fired pizzas, organic Hmong food and barbecued Mekong fish won't disappoint.
R3A Rd., Ban Khonekeo
Attached to the eponymous Riverside Hotel, this alfresco restaurant offers sweeping views of the Mekong, postcard-worthy sunsets and a mixture of Thai, Laotian and Western-style food.
Like many places in Houayxay, there isn't really a sign indicating what or where this spot is. Just follow your nose across the street from the Saybadee Guest House to tuck into sizzling barbecue, grilled sausage or sticky rice.
What to do
Houayxay's modest attractions and quaint cafes are enough to keep you distracted for a day.
Wat Chomkao Manilat
The only way up to this colorful Buddhist temple is by ascending a staircase with engraved dragon handrails to a hilltop perched above the town. Once you've made it, you can admire views across the Mekong into Thailand, tour the temple and help young monks practice their English at the daily “ask a monk” meetings.
Though it's something of a skeleton these days, the French colonial-era Fort Carnot is still standing on a hilltop near the Bokeo Governor's Office. You can climb one of the fort's two towers for prime views.
The Talat Sao morning market takes place along Houayxay's main thoroughfare, Th Saykhong, near the bus stand. Come early for hill tribe art, handicrafts and local fruit.
