Bukit Lawang
One of the last places on Earth to trek among genuinely wild Sumatran orangutans

A small riverside village on the edge of Gunung Leuser National Park, Bukit Lawang built its economy around jungle trekking to see Sumatran orangutans — critically endangered and found nowhere else on Earth outside this corner of Sumatra — in habitat that's still real rainforest, not a fenced reserve.
Quick facts
The trek
Guided treks run from a few hours to multi-day jungle camping trips, climbing steep, muddy trails through genuine rainforest — this is a real hike, not a boardwalk, and orangutan sightings (while common) depend on the animals' own movements, not a feeding schedule.
Semi-wild vs wild orangutans
Bukit Lawang's population includes both fully wild orangutans and some descended from a former rehabilitation program that ended decades ago — the animals here are genuinely wild-living now, though a handful of older individuals are more habituated to humans than truly wild ones would be, which guides can explain on the trail.
The river tubing finish
Many treks end with a float back down the Bohorok River on inflated tire tubes — a fun, low-effort way to finish a physically demanding trek and a Bukit Lawang tradition in its own right.
Practical tips
- —Book through a licensed guide association in the village rather than an unofficial freelance tout — guiding standards and safety practices vary a lot.
- —Multi-day treks (2–3 days, jungle camping) go deeper into the park and offer better odds of extended sightings than a half-day trip.
- —Wear real hiking shoes — the trails are steep, muddy, and genuinely challenging, not a casual walk.
- —Never feed or touch an orangutan, no matter how close one gets — this is for their health and safety as much as yours.
