Gunung Leuser National Park is one of the world’s most important conservation areas. Spanning the provinces of Aceh and North Sumatra, this national park covers more than one million hectares and is part of the Tropical Rainforest Heritage of Sumatra, a UNESCO World Heritage Site.
For nature lovers and adventure seekers, Gunung Leuser is more than just a place for trekking. The area offers the experience of exploring pristine tropical rainforests, observing wildlife in their natural habitats, and enjoying natural beauty largely untouched by humans.
Home to the Sumatran Orangutan
One of Gunung Leuser’s main attractions is the presence of the Sumatran orangutan (Pongo abelii). This primate is classified as Critically Endangered, with its wild population continuing to decline due to habitat loss.
In Bukit Lawang, visitors have the opportunity to see orangutans living freely in the wild. Unlike in zoos, here orangutans forage for food, build nests, and live their natural lives in the heart of the forest.
However, encounters with orangutans can never be guaranteed. It is precisely this uncertainty that makes every moment feel more precious and authentic.
Extraordinary Biodiversity
In addition to orangutans, Gunung Leuser is also home to hundreds of other animal species.
During your trek, you may encounter:
- Thomas’s Leaf Monkey
- Long-tailed Macaque
- Pig-tailed Macaque
- Siamang
- Hornbill
- Monitor Lizard
- Giant Squirrel
On expeditions deeper into the interior, there’s a chance to spot traces of Sumatran Elephants, Sun Bears, and even Sumatran Tigers.
Since all wildlife roams freely, every journey offers a unique experience.
