Mornings in Bukit Lawang begin with the river daring you to cross it — a soft, constant roar beneath a canopy that keeps daylight filtered and green. This four-day itinerary moves from the village to the heart of Gunung Leuser National Park: two days of guided trekking, one night in a simple jungle camp and nights in local guesthouses beside the Landak River.

Wildlife
History

Conservation
Deforestation and habitat loss threaten local species; choose operators that support community programs and participate in park monitoring to minimize tourism impact.

Pack river-ready footwear
Bring sturdy sandals or quick-dry shoes for multiple shallow river crossings; hiking boots can be worn uphill but will get wet during river sections.
Carry a waterproof pack cover
Rain and stream spray are common; keep electronics and spare clothes dry with a reliable rain cover or drybag.
Bring insect protection
High humidity and standing water mean mosquitoes are active; use DEET or picaridin repellent and a headnet for camp if you’re sensitive.
Follow guide instructions around wildlife
Do not attempt to touch or feed orangutans; keep voices low and distances to avoid stressing animals and disrupting conservation work.
River sandals or water shoes
Protects feet during repeated shallow river crossings and provides traction on wet rock.
Lightweight waterproof jacket
Quick rain showers are frequent; a breathable rain shell keeps you dry and cool.
Drybag or waterproof pack cover
Keeps clothing, electronics and documents safe from rain and river spray.
Headlamp with extra batteries
Needed for night-time camp tasks, early-morning river walks and dim jungle paths.
