History & Background

The story of Gunung Leuser National Park (GLNP) is a long narrative of conservation and the struggle to protect one of the most vital ecosystems on the planet. Its history is rooted in the Dutch colonial era, when the area began to be recognized as an important habitat for various rare species. In 1934, the Dutch East Indies government designated a significant portion of this region as a protected area, later known as the Leuser Nature Reserve. However, more structured conservation efforts only emerged after Indonesia's independence.

A significant milestone occurred in 1980 when the Leuser Nature Reserve was officially designated as Gunung Leuser National Park under the Decree of the Minister of Agriculture No. 440/Kpts/Um/10/1980. This designation was a crucial step in protecting the habitat of the Sumatran orangutan (Pongo abelii), Sumatran tiger (Panthera tigris sumatrae), Sumatran elephant (Elephas maximus sumatranus), Sumatran rhinoceros (Dicerorhinus sumatrensis), and a host of other endemic species. Spanning 7,927 square kilometers, GLNP is the largest national park in Indonesia and one of the most important in Southeast Asia.

Over the subsequent decades, GLNP faced numerous challenges, including forest encroachment for oil palm plantations, illegal logging, wildlife poaching, and human-wildlife conflict. However, thanks to the persistent efforts of the government, international and local conservation organizations, and growing public awareness, GLNP continues to fight for its survival. In 2011, GLNP became part of the UNESCO World Heritage Site "Tropical Rainforest Heritage of Sumatra," alongside Kerinci Seblat National Park and Bukit Barisan Selatan National Park, a global recognition of its extraordinary conservation value.

This area is not only ecologically significant but also holds deep cultural value for the indigenous communities who inhabit it, such as the Gayo, Alas, and Batak Karo tribes. Their lives have long been intertwined with the forest, depending on its resources for their survival and cultural richness. Their traditional knowledge of the forest and its wildlife often plays a key role in conservation efforts.

Today, GLNP remains a focal point for scientific research, responsible ecotourism activities, and conservation programs to ensure the preservation of this invaluable natural heritage for future generations. Exploring Leuser means stepping into the living history of conservation and witnessing the ongoing marvels of evolution.

Main Attractions

Gunung Leuser National Park (GLNP) is a breathtaking mosaic of natural beauty, offering a diverse range of unforgettable experiences for every visitor. Its extraordinary biodiversity is the main draw, making it one of the most important ecotourism destinations in the world.

1. Sumatran Orangutan (Pongo abelii)

Without a doubt, the Sumatran orangutan is the icon of Leuser. GLNP is one of the last two remaining habitats for this rare primate. The most thrilling experience is seeing them in their natural habitat. The orangutan rehabilitation and conservation centers in Bukit Lawang and Ketambe offer incredible opportunities to observe them, especially during feeding times. Trekking through the dense jungle and suddenly spotting a mother orangutan swinging from tree to tree, or a playful baby orangutan, is a moment that will be etched in your memory forever.

2. Mount Leuser Peak

For true mountaineers, conquering the peak of Mount Leuser (3,404 masl) is the ultimate challenge. This ascent typically takes several days, passing through dense tropical rainforest, rushing rivers, and dramatic natural landscapes. The view from the mist-shrouded summit offers an incredible sense of achievement. Keep in mind that this climb requires good physical preparation, adequate gear, and an experienced local guide.

3. Rich Tropical Rainforest Ecosystem

Leuser is home to an astonishing array of biodiversity. Besides orangutans, you might have the chance to see other wildlife such as:

• Sumatran Tiger (Panthera tigris sumatrae): Extremely rare and difficult to spot, but its presence adds an aura of mystery to the forest.
• Sumatran Elephant (Elephas maximus sumatranus): Elephant herds are often seen in certain areas, especially near rivers.
• Sumatran Rhinoceros (Dicerorhinus sumatrensis): The most endangered species, rarely sighted.
• Long-tailed Macaques (Macaca fascicularis), Siamangs (Symphalangus syndactylus), Langurs (Trachypithecus spp.): Other commonly encountered primates.
• Various exotic bird species: Including Hornbills, Birds of Paradise (though rarer in Leuser than Papua), and numerous songbirds.
• Reptiles and amphibians: Various types of snakes, lizards, and frogs.

The floral beauty is equally captivating, with giant trees, wild orchids, and abundant medicinal plants.

4. Alas River & Wampu River

These rivers are not only lifelines for the ecosystem but also offer exciting activities. White Water Rafting on the Alas River, particularly from Kedah to Gelombang, provides a thrilling adventure with stunning jungle scenery on both sides. The Wampu River also offers equally challenging rafting routes.

5. Tourist Villages & Local Culture

The areas surrounding GLNP are inhabited by various ethnic groups, such as the Gayo and Alas. Visiting villages like Bukit Lawang, Ketambe, Kuta Cane, or Singkil provides an opportunity to interact with local communities, learn about their traditions, taste local cuisine, and understand how they live in harmony with nature. The renowned Gayo coffee culture is also a significant attraction.

6. Caves & Waterfalls

Within and around the GLNP area, there are mysterious caves and refreshing waterfalls. Waterfalls like Lawe Gerudung Waterfall or Sikulikap Waterfall offer beautiful spots to relax after trekking or simply enjoy the natural beauty.

Every corner of Leuser holds a story and a wonder. Whether you are a wildlife observer, a mountain climber, a river explorer, or a cultural enthusiast, GLNP has something special to offer.
