Gunung Leuser National Park (GLNP) is one of the largest and most important conservation areas in Indonesia. Located in the provinces of Aceh and North Sumatra, this national park spans over 1 million hectares. As part of the UNESCO World Heritage site in the category of Tropical Rainforest Heritage of Sumatra, GLNP is home to a wide variety of endemic flora and fauna, making it a top destination for nature lovers and researchers.
GLNP stretches across two provinces, with the most well-known entrance located in Bukit Lawang, North Sumatra. This location can be accessed from Medan, the capital of North Sumatra, by a 3-4 hour drive. Another entrance is Ketambe in Southeast Aceh, which offers a quieter experience and is ideal for long trekking trips.
Gunung Leuser National Park is renowned for its rich biodiversity. The area serves as a critical habitat for several rare and endangered species, including:

Sumatran Orangutan (Pongo abelii). GLNP is one of the best places in the world to see Sumatran orangutans in their natural habitat. They are often spotted around Bukit Lawang, making it a major attraction for visitors.
