Cambodia’s recently opened Mekong Discovery Trail is a fun, cheap and effectively low-impact approach to improving the socio-economic problems of northeastern Cambodia’s poor Mekong region, where 77 per cent of locals exist on less than $2 per day.

Established by a Dutch NGO ( and the United Nations World Tourism Organization (, the trail has funded development of a modest local infrastructure that enables travellers to cycle or hike signed riverside footpaths, to go dolphin-watching, and stay with families in traditional Khmer villages.

It also offers guidance to buying local foods and handicrafts.

The project area runs 180km north-east from Kratie along the Mekong towards Laos. Typically travellers ignore this beautiful corner for the more popular Angkor Wat in Western Cambodia. But here any money spent goes straight in the pockets of local Khmer communities — no middlemen.

The eco-trail also aims to preserve rare Irrawaddy river dolphins — fewer than 70 now live in the river.

“We hope that tourism will provide alternative livelihoods to take locals out of fishing and conserve the dolphins,” UNWTO’s Marcus Sandford tells me over a cold beer in the city of Kratie.

Kratie hugs the mighty Mekong and has clearly seen better days. I hung around for a few days enjoying the colourful market and feasting on exotic fruits such as lotus flower-pods, which resembled rubbery showerheads.

Next to my guesthouse, thousands of monks flocked to Kratie’s mustard-coloured temple (wat) for a Buddhist celebration. Each night I sipped a sundowner by the Mekong, watching its swirling waters glisten blood-red.

Renting a motorcycle, I then set off with the trail’s handbook on a two-day Mekong adventure.

Crossing the Mekong by river-ferry I spent my first day bumping along dirt tracks, crossing dodgy bridges, through riverside Khmer communities.

The locals see few visitors. So whenever I stopped, hoards of children appeared hollering ‘varang’ (foreigner).

At Wat Neak Kro Thearan, a posse of children followed me around the Buddhist temple’s vivid interior of a golden Buddha backed by psychedelic murals.

I stopped to photograph weddings where brides habitually wore scarlet; hit traffic jams of water buffalo and paused to take in the muddled islands and rapids of the Mekong’s braided channel.

How did my presence help the local Khmer communities? Stopping in the villages I bought local fuel, ice-shakes made from blended bananas, pineapples, and pungent durian, and paused to eat sticks of krolon (bamboo tubes of sweetened sticky rice) or barbecued fish and rice.

I also put a few Cambodian riels into the local economy by enjoying the trail’s newly arranged homestays. A few days upriver I would stop with a delightful family near the Laotian border in a thatched two-storey house at O’Svay village to spend an evening listening to gripping tales of their lives under the Khmer Rouge regime.

On this motorcycle excursion, however, I was the first paying guest to stay at Cambodia’s largest active monastery, Mouy Rouy.

The monks showed me the colourful temple, surrounded by mango trees, and explained they revered a supernatural monk who could morph into a crocodile. I sat chatting to them long into the evening as croaking frogs and clucking geckos electrified the sultry night air.

Temple cymbals and bells roused me early next morning, so I drove through the Mekong’s dewy mist to Kampi Dolphin Pool. My boatman was an ex-fisherman who was now earning far more by punting tourists out into deep-water pools to see the dolphins than from fishing.

Floating on the Mekong’s silky surface, we hovered motionlessly, waiting. It wasn’t long before the dolphins appeared, emitting a laboured wheeze before breaking the surface with their bulbous heads.

Glistening in the morning sunrise, five floated serenely around our boat for nearly an hour.

I felt somewhat saintly that my choice of holiday was helping to secure their future.

Avoid greenwash 

Choosing an eco-friendly holiday presents a minefield of choices as seemingly every holiday these days is prefixed with either ‘green’ or ‘eco-’.

But how many of these are actually kosher or simply greenwash? I once read a brochure boasting about the green credentials of a massive new five-star hotel and golf complex carved out of virgin rainforest in Malaysia.

This wasn’t just greenwashing: it was taking the piss.

There are many things to weigh up when choosing an eco-friendly holiday.

My trip to Cambodia put money directly into the pockets of impoverished local communities, yet my long-haul flight pumped a significant amount of greenhouse gas into the atmosphere.

Pedal power

Green-powered adventures await on the National Cycle Network ( Take National Cycle Route 4, and pedal from London to Bath before returning by train. Much of the section beyond Reading is via the beautiful and historic Kennet & Avon Canal.

Africa’s toughest climb (5895m) is tightly controlled to benefit Kilimanjaro’s environment and provide local employment. The National Park insists that all rubbish is carried off Kili, gas-stoves are used to preserve
trees from cooking fires, and fair rates of pay and good welfare standards exist for porters. Less-travelled ascents such as Kilimanjaro’s Rongai Route have little human impact.
