Mount Leuser National Park – into the heart of Sumatra’s rainforest

Sprawling across more than 7,500 square kilometers in North Sumatra and Aceh, Mount Leuser National Park is one of Southeast Asia’s last great wildernesses. Part of the UNESCO-listed Tropical Rainforest Heritage of Sumatra, it protects a rich world of towering trees, winding rivers, and rare wildlife. Orangutans, elephants, hornbills, and even the elusive Sumatran tiger all find refuge in this untamed jungle.

The journey often begins in Bukit Lawang, a riverside village that opens the door to thrilling rainforest adventures. From short treks to multi-day expeditions, every path reveals something unforgettable—swinging gibbons in the canopy, hidden waterfalls, and the call of hornbills echoing through the valley. For many, floating down the Bohorok River after a day of trekking is the perfect way to soak in the park’s raw beauty.

Beyond its wildlife encounters, Leuser is about immersion in nature at its purest. Nights in jungle camps bring the symphony of cicadas and fireflies, while days are filled with the earthy scent of the forest. Every step into Leuser feels like stepping into a living, breathing treasure—one of the planet’s most important lungs, waiting to be explored.
