Khao Yai is Thailand's only primary tropical rainforest designated a UNESCO World Heritage Site, just 2.5 hours from Bangkok — distinct from a cultural tour or a van circuit. Les Collines Khao Yai has operated here since 2005, the only resident English-speaking naturalist agency in the region.
What makes a jungle trek authentic? · Khao Yai vs Chiang Mai — full comparison
Our treks aren't "guided tours with a species checklist." Each one is built so you leave understanding what you saw — why that animal was there, how it moves, what its presence says about the forest. Children, seniors, seasoned trekkers: the difference is evident within the first hour.
"An unforgettable custom trek. Passionate guides, wonderful team, warm welcome from Cédric and Potjana. You come back changed."
"Outstanding experience. Flawless organization, deep respect for the wildlife, the park, and the local team. Exactly what we were looking for."
"Perfect stay. Charming accommodations, a trek that worked perfectly for our kids, and that rare feeling of being part of something — not just passing through."

🌳 "Khao Yai's jungle is open to everyone!" 😄🦋
As light fades, porcupines, civets, deer, and buffy fish-owls emerge into the forest's most active hours. This is the narrow window we work within — not an extended nighttime pursuit that exhausts both wildlife and guests for an uncertain payoff. Less time, more encounters, zero disturbance. This is the discipline that separates a genuine naturalist practice from an operator selling "a night in the jungle" as a marketing line.
We do not design this trek to be accessible to everyone. We design it for those who recognize, in the field, the difference between an improvised outing and twenty years of discipline — and who refuse to trade one for the other.
This trek is not designed for everyone. It is designed for those who know precisely what they are seeking — genuine immersion, a team that compromises neither safety nor respect for wildlife, and the time it takes to do this properly. Twenty years in the field, a permanent, salaried team — this is what shows up in every detail of the stay.

Khao Yai is one of Asia's top parks for wildlife observation: gibbons, hornbills, deer, reptiles, raptors… Elephants are present, but sightings depend on their natural movements.

Closed-toe shoes, lightweight cover-up clothing, rain jacket, hat, insect repellent, and sunscreen. For multi-day packages, we provide all necessary equipment.
