History & Background

The Leuser Ecosystem boasts a rich and complex history, rooted deep in time long before modern humans inhabited this region. Geologically, it's part of Sumatra's active volcanic belt, shaping its dramatic mountainous landscapes and fertile valleys that provide habitat for extraordinary biodiversity. For thousands of years, this area has been home to various indigenous ethnic groups of Sumatra, including the Gayo, Alas, Kluet, and Batak peoples, each with their unique stories, languages, and customs. They lived in harmony with nature, relying on the forest for food, medicine, and building materials, and developed a profound traditional knowledge system about this ecosystem.

In the 20th century, the remarkable conservation value of the Leuser forests began to attract international attention. In 1980, Gunung Leuser National Park (TNGNL) was officially established, covering an area of approximately 7,927 square kilometers. The park's creation was a response to the increasing threats of deforestation due to illegal logging, land conversion for plantations, and poaching. Since then, Leuser has become a focal point of global conservation efforts, recognized as one of the most important lowland and montane tropical rainforest ecosystems in the world.

Conservation efforts in Leuser have gone through various phases, including scientific research, species protection programs, local community empowerment, and policy advocacy. Environmental scientists and activists from various national and international organizations have dedicated themselves to preserving Leuser's integrity. Leuser's recognition as a UNESCO World Heritage Site in 2011 (as part of the Tropical Rainforest Heritage of Sumatra) further solidified its status as a global conservation priority area. However, the struggle to protect Leuser continues, facing challenges such as climate change, development pressures, and the need to balance nature conservation with the well-being of the communities dependent on forest resources. The history of Leuser is a story of a tenacious fight to preserve invaluable nature and cherish the living cultural heritage that coexists with it.

Main Attractions

Leuser offers an unparalleled combination of wild natural beauty and untouched cultural richness, making it a paradise for true explorers.

Extraordinary Biodiversity

The heart of Leuser's allure lies within the vast Leuser Ecosystem, one of the last remaining habitats for some of the world's most iconic and endangered species.

Sumatran Orangutan (Pongo abelii): Witnessing orangutans swinging freely in their natural habitat is an incredibly moving experience. Areas like Ketambe and Bukit Lawang (though technically bordering the park but ecologically integrated) are popular starting points for trekking and orangutan observation. Orangutan reintroduction programs at rehabilitation centers also offer opportunities to learn about their conservation efforts.
Sumatran Elephant (Elephas maximus sumatranus): Although harder to spot due to their nomadic nature, the presence of Sumatran elephants in Leuser signifies a healthy ecosystem. Guided tours that respect their living space can provide rare chances to see their tracks or even herds in the distance.

Trekking in remote areas with experienced guides can increase the chances of finding footprints or hearing their calls.
