Why Choose Gunung Leuser National Park for Jungle Trekking?
Biodiversity at Its Best
Gunung Leuser is renowned for its incredible wildlife. The park is home to the critically endangered Sumatran orangutans, along with other rare species such as tigers, rhinos, elephants, and a wide variety of birds and primates. It’s one of the few places where you can trek through the jungle and spot these magnificent creatures in their natural habitat.
Diverse Trekking Routes
The park offers a range of trekking trails for different fitness levels and adventure preferences. Some trails are shorter and easy to navigate, while others, like multi-day treks to the summit of Gunung Leuser, are more challenging and take you deep into the heart of the jungle. No matter which trail you choose, you’re bound to encounter spectacular views, dense forests, and possibly, wildlife sightings.
Local Guides and Safety
Hiring a local guide is highly recommended for jungle trekking in Gunung Leuser. Not only do the guides know the best spots to view wildlife, but they are also experts in navigating the park’s complex trails. They’ll ensure your safety while sharing their knowledge of the jungle’s flora and fauna. Most guides also take you on treks to remote areas where wildlife sightings are more likely. It is also a perfect way to start your interaction with the locals!

The trek also takes you through areas that are less visited, providing a more secluded and immersive experience.

What to Expect Trekking in Gunung Leuser
Wildlife Encounters
One of the main attractions of trekking in Gunung Leuser is the opportunity to see orangutans in the wild. While sightings aren’t guaranteed, the park has one of the highest populations of orangutans in Sumatra. Keep an eye out for gibbons, long-tailed macaques, and other jungle creatures like hornbills and sun bears. The wildlife experience is truly one of a kind, and with the help of a knowledgeable guide, you’re likely to encounter several species along the way.
Stunning Landscapes, Caves and Rivers
As you trek through the park, you’ll pass through lush forests, towering trees, and clear streams. Gunung Leuser is home to several impressive waterfalls that make for perfect spots to relax or swim after a long day’s trek. The Bohorok River, which runs through Bukit Lawang, offers a serene and scenic view as you hike along its banks.
Rich Flora
The park’s diverse flora is equally as captivating as its fauna. Expect to see a wide variety of tropical plants, from medicinal herbs to giant trees and vibrantly colored orchids. The dense jungle is teeming with life, and every step you take will reveal something new and beautiful. Most importantly (at least for me), Sumatra is home to two of the most fascinating flowers: the corpse flowers Amorphophallus titanum or Rafflesia arnoldii.
Best Time to Visit Gunung Leuser National Park
The ideal time for trekking in Gunung Leuser is during the dry season, from May to September. During this period, the trails are more accessible, and the weather is more conducive to outdoor activities. While the wet season (October to April) brings heavy rains, it’s still possible to trek during this time, though the trails can become muddy and challenging.
