Best Trekking Routes in Gunung Leuser National Park

Top Trekking Routes in the Leuser Ecosystem

The Gunung Leuser National Park is one of the world's most biodiverse rainforests, spanning two provinces across North Sumatra and Aceh. Within this vast wilderness, a network of trekking trails awaits adventurous visitors of all fitness levels.

Beginner Trails (1–3 Hours)

Riverbank Nature Walk: The most accessible trail, following the Buluh River through lowland rainforest. Ideal for families and first-time jungle trekkers. Guided tours are available and highly recommended.

Forest Edge Loop: A circular trail that skirts the boundary of primary forest, offering excellent birdwatching opportunities and a chance to spot monitor lizards and macaques.

Intermediate Trails (4–6 Hours)

Hidden Waterfall Trek: A moderately challenging route leading to a series of cascading waterfalls deep in the jungle. The trail crosses streams and traverses root-tangled terrain — proper hiking shoes are essential.

Wildlife Spotting Trail: Venture deeper into primary forest where orangutans, Thomas leaf monkeys, and sun bears have been sighted. Patience is rewarded on this trail.

Advanced Routes (Full Day / Multi-Day)

Leuser Summit Approach: For experienced trekkers, a challenging ascent through montane forest offers panoramic views above the cloud layer. This requires advance booking and permits.
