Our treks
One forest. Six ways to lose yourself in it.
Most routes end the same way: a tube rafting return down the Bohorok river. What changes is how deep you go, and how many nights the jungle keeps you. The one exception is the 7-day expedition, which crosses the whole park and ends on the other side, at Kutacane in Aceh.

Good to know
A few honest answers
Will I really see orangutans?
These are wild animals, so sightings can never be guaranteed. However, our guides know the forest inside out. They read the signs: a rustle in the leaves, a distant call, or tracks on the ground. Bukit Lawang is one of the best spots in Sumatra for this. Some of the park's orangutans are former rehabilitation-centre residents: fully free today, they remain used to people.
Do I need to be fit?
The pace is set by the group, not a fixed schedule. Most treks suit a reasonable level of fitness; only the 7-day route is demanding.
What if it rains?
Treks go ahead as planned: this is a rainforest, after all. Rain often means a quieter trail and a more active jungle.
Can someone carry my bag?
Yes. A porter can join for an extra fee, and it also means an extra person from the village earning a day's work.
