Jungle trek and wildlife safari at Khao Yai with Les Collines – Wild elephants and gibbons in their natural habitat

See All-Inclusive Packages →

You begin at Les Collines Khao Yai, our private eco-lodge at the park's edge, guided by a naturalist team — Cédric, Whisky, Rung, and Noey — with more than twenty years on this exact terrain. No script, no fixed itinerary.

Note: We deliberately cap departures during peak season — for the wildlife, for our team, and for you. A limited number of slots remain on certain dates.

The Best Jungle Trek in Thailand — Why Khao Yai Stands Apart

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

Close Enough to Reach. Wild Enough to Matter.

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.

Plan an Accessible Trek

The Dusk Safari — Not a Sleepless Night, a Respected Window

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.

An Experience Built for the Few

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.

Frequently Asked Questions — Trekking at Khao Yai

Is the trek suitable for children?

Yes, absolutely from age 4–5. The Discovery and Adventure packages are ideal for families. The pace is adapted, and our guides are experienced at trekking with children.

What fitness level do I need?

All our treks are accessible. Discovery = easy walk on approved trails. Adventure = full day but fully modular. Explorer = more intense immersion for active travelers.

Will we actually see wildlife?

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.

Is it safe to go into the jungle?

Yes. Every outing includes an English-speaking tour leader, a local park guide, and a sworn forest ranger. All routes are 100% authorized, declared, and monitored.

What should I pack?

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

What if there's rain or bad weather?

Treks still run — the jungle is even more alive in the rain. If there's a genuine risk (storms, high winds), we adjust the route or offer an alternative time slot.

Are the treks suitable for seniors?

Yes. Many guests aged 55–80 join the Discovery and Adventure packages. We adapt pace, distance, and break frequency.

Can we bring a very young child?

Yes, from age 4–5 for the gentler packages. Infants can join if carried in a backpack carrier (provided by parents).

How do I pay?

Payment by Stripe, bank transfer, or cash in THB only. A deposit secures your date; the balance is due 7 days before arrival.

Can I modify or cancel a booking?

Up to 7 days before: changes at no charge. In case of unexpected events (illness, delayed flight), we offer flexible alternatives where possible.
