Khao Yai is one of Thailand's largest tropical forests listed as a UNESCO World Heritage Site, about 2 hours from Bangkok on the M6 motorway. This is a nature trek, not a cultural tour or a van excursion. Les Collines Khao Yai has worked here since 2005 and is the only French and English-speaking operator based on site year-round.
Where do you sleep, and at what pace? We stay in Pak Chong, in 7 villas and dormitories, 35 minutes from the park. The pace is a holiday pace: breakfast at 7 am with pastries, walks start around 8 to 8:30 am. Tours with overnight stays include full board.

A permanent team, employed year-round, with you from arrival to the last meal. No passing freelancers.
We don't tick off a species list: the guides explain what you see and what its presence says about the forest. Children, seniors or seasoned hikers, everyone gets something out of it.
"Just a PERFECT, UNIQUE and EXCEPTIONAL trek. The team is caring, professional and attentive. We (a family with a child and a teenager) discovered a host of incredible animals over a full day. Everything taken care of from A to Z, a day full of discoveries, good mood and laughter. A must, and one to do again without hesitation!" (translated from French)
"Authenticity, warmth, a magnificent trek... what more can I say... Go for it with your eyes closed! Absolutely magnificent! The contact with the guides was truly extraordinary, for adults and for young people aged 18-20 alike. The jungle trek was great and you keep learning about the jungle the whole time. It is much more than a walk looking for wildlife. We also loved the friendly evening meals with the other guests. On the second evening we even ate a meal cooked by a couple who had taken the cooking class option (from market shopping to cooking)." (translated from French)
Our prices are per private group, not per person : the more of you there are, the lower the price per person. Here is the group price, the same as in the detailed table below, and what it works out to per person for 2 or 4 travellers (2026-2027 rates, euros indicative at ≈ 37 ฿).

🌳 "The Khao Yai jungle is open to everyone!" 😄🦋
A real immersion, with a team that makes no compromise on safety or respect for wildlife. Twenty years in the field, a permanent team employed year-round : it shows in every detail of your stay.
At nightfall, porcupines, civets, deer and fish owls start to become active. We go out during this short window and do not extend it: night-time tracking disturbs wildlife for uncertain results. Less time, more encounters, zero disturbance.
We did not design this trek to please everyone. It is for those who prefer twenty years of field experience to an improvised service.

👨👩👧👦 Program adapted to your children's ages and your fitness: gentle or sporty walking, we decide together, in strict compliance with park rules.
Yes, from age 5. The Observation and Adventure tours are ideal for families. The pace is adapted and our guides are used to accompanying children. Babies can join in a baby carrier backpack (provided by the parents).
All our treks remain accessible. Observation : gentle walking on authorised trails. Adventure : flexible full day. Explorer : a more intense immersion for active travellers.
Khao Yai is home to over 400 wild Asian elephants roaming completely free. Sightings are possible but not guaranteed: it depends on their natural movements. Gibbons, hornbills, deer, reptiles and birds of prey are seen far more regularly.
Yes. Every outing is led by an English or French-speaking tour leader, together with a licensed park guide or a sworn park ranger; on deeper treks both are mandatory. Routes are 100% authorised, declared and monitored.
The cool season (November to February) is ideal: very active wildlife, passable trails, pleasant nights. The rainy season (May to October) brings a lush jungle and spectacular waterfalls. See the table above and our month-by-month guide.
Khao Yai is a UNESCO primary forest with large wildlife (400+ elephants, gibbons, hornbills). Chiang Mai offers cultural treks in secondary mountain forest, with hill-tribe villages. They are two complementary experiences, not substitutes. Full comparison →
Closed shoes, light covering clothes, a rain jacket, a hat, insect repellent and sunscreen. For longer tours, we provide all the gear you need.
Treks still go ahead: the jungle is even more beautiful in the rain. If there is a real risk (storms, strong winds), we adjust the route or offer another slot.
Yes. Many travellers aged 55 to 80 join the Observation and Adventuretours. We adapt the speed, the distance and the length of breaks.
Prices are per private group, not per person, in Thai baht. The most affordable tour, Discovery Observation (1 day), starts at 13,000 ฿ for 2 people, about 6,500 ฿ per person. A 3-day, 2-night stay (Adventure tour) starts at 23,000 ฿ for 2, about 11,500 ฿ per person, and the price per person drops from 3 travellers. There is no child rate. See the budget by tour →
Not for the Observation, Adventure, Explorer and Safari Premium tours: the Bangkok - Pak Chong journey is not included and we welcome you in Pak Chong (hotel, bus station or train station). A private transfer from Bangkok can be arranged on request. It is included in the From Red to Greentour, in Wild Expedition and in the Adventure Plus.
Payment by Stripe, bank transfer or cash in THB only. A deposit confirms your date, and the balance is due 7 days before arrival.
Up to 7 days before arrival, changes are free. In case of the unexpected (illness, delayed flight), we offer a flexible solution wherever possible.
