How the day runs
Jahoo collects you in Sen Monorom in the dark and drives back down National Road 76 to Keo Seima Wildlife Sanctuary. Bunong guides lead the way to where the habituated gibbon family slept, so you are there when the dawn duet begins. You then follow the family at a respectful distance as it feeds and moves, before a forest walk with breakfast and lunch, looking for black-shanked douc langurs, birds and other wildlife. You are back in town in the afternoon.
The two-day option adds a night at Jahoo’s bamboo camp with a night walk for nocturnal wildlife; the three-day option goes further into the forest.
Who it suits
Fit travelers aged 10 and over who are happy with an early start, heat and steep, uneven paths. It is the stronger choice for wildlife photographers and anyone who wants wild animals rather than a sanctuary. Families with younger children are better served by a half day at the Elephant Valley Project.
Planning around it
Stay in Sen Monorom the night before; the trek cannot be reached from Phnom Penh on the same morning. In the wet season the last stretch to the camp can be too muddy for vehicles, so you may walk the final part.
What to bring
- Closed walking shoes with grip and long trousers
- A light layer for the early start; rain jacket in the wet season
- Camera with a zoom lens if you want photographs of the canopy
What we confirm before you book
- Availability on your date (one tour per day for up to six guests)
- Current price, payment method and Jahoo’s cancellation terms
- Pickup time and wet-season access to the camp
- Children’s ages (minimum age 10)

Questions travelers ask
How likely am I to see gibbons?
Likely but not guaranteed. The family is habituated to people and the guides start at dawn when gibbons call, which gives good odds. Views can be brief because gibbons live high in the canopy.
Is the one-day trek enough?
For most visitors, yes. The two-day option adds a night walk and a second dawn in the forest, which improves both your chances and your photographs.
