The Best Jungle Trek in Thailand. Why Khao Yai Stands Apart
Khao Yai is one of Thailand's largest tropical forests designated a UNESCO World Heritage Site, about 2 hours from Bangkok on the M6 motorway. It is a nature trek, not 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.
🌿 UNESCO primary forestDong Phayayen–Khao Yai, 615,000 unbroken hectares.
Where do we sleep, and at what pace? We sleep in Pak Chong, in 7 villas and dormitories, 35 minutes from the park. The pace stays that of a holiday: breakfast at 7:00 AM with pastries, walks leaving around 8:00-8:30. Packages that include nights are full board.
A permanent, salaried team you meet from the welcome to the last dinner. No passing contractors.

Close Enough to Reach. Wild Enough to Matter.
Our treks aren't guided tours with a species checklist: your guides explain what you see and what its presence says about the forest. Children, seniors or seasoned trekkers, everyone finds their place.
"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."

Genuine immersion, with a team that compromises neither on safety nor on respect for wildlife. Twenty years in the field, a permanent, salaried team: it shows in every detail of the stay.
🌿 EthicalWildlife is never disturbed for a photograph, group sizes are deliberately limited, sworn rangers accompany every outing.
🤝 CandidWe state plainly what we cannot guarantee. No promise of elephants "guaranteed": that is the truth of the terrain.
❤️ CommittedA local team, salaried year-round, continually trained and invested in the trek's outcome.
⭐ ExactingFully private groups, a high guide-to-guest ratio, equipment and logistics designed to leave nothing to chance.
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, never an extended night hunt that disturbs the wildlife for an uncertain payoff. Less time, more encounters, zero disturbance.
🔦 Quiet observation: no harsh floodlights, no staging for a photograph
🌿 Sworn ranger on every outing; wildlife is never compelled to appear
🏕️ Overnight in a park bungalow for full immersion, with no forced night excursion (Explorer & Safari Premium packages)
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.
Day 2. Early Departure, Primary Forest Trek, Overnight in the Park
🥐 Breakfast with homemade pastries, then drive to the park with guide and rangers
🚶 Trek calibrated to your fitness level (5–15 km): gibbons, hornbills, elephant tracks, viewpoints and waterfalls

🗓️ Detailed Program
Day 1. Bangkok → Ayutthaya → Khao Yai: Pickup in Bangkok in the morning (single meeting point).

Isan extension (on request, instead of Bangkok return)
Yes, from age 5. The Discovery and Adventure packages are ideal for families. The pace is adapted and our guides are experienced at trekking with children. Infants can join if carried in a backpack carrier (provided by parents).
What fitness level do I need for a trek at Khao Yai?
All our treks are accessible. Discovery = easy walk on approved trails. Adventure = full day, fully modular. Explorer = more intense immersion for active travelers.
Will we actually see wild elephants at Khao Yai?
Khao Yai is home to over 400 wild Asian elephants roaming freely. Sightings are possible but never guaranteed, their presence depends on their natural movements. Gibbons, hornbills, deer, reptiles and raptors are seen far more regularly.
Is it safe to trek in the Khao Yai jungle?
Yes. Every outing is supervised by an English-speaking tour leader, a local park guide, and a sworn forest ranger. All routes are 100% authorized, declared and monitored.
What is the best season for a jungle trek at Khao Yai?
The cool season (November–February) is ideal: very active wildlife, walkable trails, pleasant nights. The wet season (May–October) offers lush jungle and spectacular waterfalls. See the table above and our month-by-month guide.
What is the difference between a trek at Khao Yai and one at Chiang Mai?
Khao Yai is a UNESCO primary forest with large wildlife (400+ elephants, gibbons, hornbills). Chiang Mai offers cultural treks through mountain secondary forest with hill-tribe villages. They are two complementary experiences, not interchangeable. Full comparison →
What should I pack for a trek at Khao Yai?
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 is 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 to 80 join the Discovery and Adventure packages. We adapt pace, distance and break frequency.
How much should I budget for a trek at Khao Yai?
Rates are for the private group, not per person, in Thai baht. The most accessible package, the Discovery Trek (1 day), starts at 13,000 THB for 2 people, about 6,500 THB per person. A 3-day, 2-night stay (Adventure Package) starts at 23,000 THB for 2, about 11,500 THB per person, and the price per person drops from 3 travelers. There is no child rate. See the budget by package →
Is transport from Bangkok included?
Not for the Discovery, Adventure, Explorer and Safari Premium packages: the Bangkok - Pak Chong trip is not included, and we meet you in Pak Chong (hotel, bus station or train station). A private transfer from Bangkok can be arranged on request. It is included in From Red to Green, in Wild Expedition and in the Adventure Plus option.
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 arrival, changes are free of charge. In case of unexpected events (illness, delayed flight), we offer flexible alternatives where possible.
