Gunung Leuser National Park is one of the most important natural treasures in Indonesia. Located on the island of Sumatra, this vast protected area covers around 1 million hectares, making it the second-largest national park in Sumatra. Gunung Leuser National Park is widely known for its rich rainforest and rare wildlife.
Gunung Leuser National Park lies between the provinces of Aceh and North Sumatra and is surrounded by the Barisan Mountain Range. The park is part of Southeast Asia’s largest remaining wilderness area, known as the Leuser Ecosystem, which spans about 2.6 million hectares.
Gunung Leuser National Park was officially designated in 1980. In 2004, it became a UNESCO World Heritage Site as part of the Tropical Rainforest Heritage of Sumatra. Despite its status, the park was placed on the World Heritage Sites in Danger list in 2011 due to threats such as illegal logging and palm oil plantations.
Gunung Leuser National Park is one of the most biologically diverse conservation areas on Earth. The park is home to about 750 animal species and nearly 10,000 plant species. This includes more than 200 mammals, 380 bird species, and 190 species of reptiles and amphibians.
Gunung Leuser National Park is globally famous for its wild Sumatran orangutans. There are only about 13,000 Sumatran orangutans left in the world, and this park is one of the few places where they can still be seen in their natural habitat.
Gunung Leuser National Park is also the only place on Earth where orangutans, elephants, tigers, and rhinoceroses live together in the wild. Other wildlife includes sun bears, gibbons, Sunda clouded leopards, pigtail macaques, and Thomas leaf monkeys. The park’s birdlife is equally impressive, especially its iconic hornbills.
Gunung Leuser National Park has a tropical rainforest climate. The dry season runs from late April to October, with temperatures often above 30°C. The wet season lasts from October to March, with November and December being the rainiest months. The wet season is considered the best time to spot orangutans because fruit trees are more abundant.
Gunung Leuser National Park has two main access points, Bukit Lawang and Ketambe. Bukit Lawang is about 85 kilometers from Medan, while Ketambe is around 226 kilometers away. Both villages offer a true wilderness experience due to their remote locations.
Gunung Leuser National Park is easier to access from Bukit Lawang, which is located along the Bohorok River. The village has more tourist facilities such as hostels, restaurants, and shops. Ketambe, located along the Alas River, is deeper inside the park and offers a more remote and wild experience.
Gunung Leuser National Park requires all visitors to enter with a licensed guide. A daily entrance fee of 150,000 IDR applies to foreign visitors. Jungle trekking prices vary, and visitors are advised to choose ethical guides who prioritize animal welfare.
Gunung Leuser National Park is best explored through jungle trekking, which is the park’s main activity. Treks can last from several hours to multiple days. Multi-day treks offer better chances to see rare animals such as elephants and tigers.
Gunung Leuser National Park also offers river tubing, especially in Bukit Lawang. Visitors float down the river for about 15 kilometers over three hours, enjoying jungle views and wildlife along the banks.
Gunung Leuser National Park allows overnight jungle camping on guided tours ranging from 2 to 9 days. These trips increase wildlife sightings but require good physical fitness and higher costs.
Gunung Leuser National Park is named after Mount Leuser, one of the highest mountains in Sumatra at 3,466 meters. Climbing Mount Leuser is a demanding 14-day trek covering 102 kilometers round trip and is considered one of the toughest adventures in Indonesia.
Gunung Leuser National Park typically requires a stay of at least 2 to 3 days for a meaningful visit. Average travel costs range from £65 to £75 per person per day, mainly due to guide fees and entrance costs, despite very cheap accommodation and food.
Gunung Leuser National Park remains a must-visit destination in Sumatra. With its vast rainforest, rare wildlife, and global conservation value, it stands as one of the most unique and important natural sites in the world.
