This rustic eco-tourism village offers a rare opportunity for adventurous travelers to trek into the jungle and witness orangutans swinging freely through the treetops.

Whether you’re a wildlife lover, trekking enthusiast, or a curious backpacker, Bukit Lawang promises a soul-stirring encounter with nature. Here’s your full guide to planning the ultimate Bukit Lawang trekking to see orangutans in 2025.

Introduction to Bukit Lawang

Bukit Lawang is located in North Sumatra, approximately 86 kilometers northwest of Medan, Indonesia’s fourth-largest city. The village sits along the Bohorok River, at the gateway to Gunung Leuser National Park—one of the richest tropical rainforests in Southeast Asia.

Bukit Lawang is world-renowned for its orangutan sanctuary and jungle trekking tours. Since the 1970s, it has served as a rehabilitation center for orangutans rescued from captivity. While the center has since closed, the village now thrives on sustainable tourism and guided treks to view these gentle giants in their natural environment.

The Fascinating World of Sumatran Orangutans

• Endangered Yet Enchanting

Sumatran orangutans are among the most intelligent and rare primates on Earth. As of 2025, fewer than 14,000 individuals are estimated to exist in the wild, all within the forests of Sumatra. These arboreal creatures are known for their long orange fur, solitary nature, and incredible nesting abilities.

• Wild vs Semi-Wild Orangutans

While many orangutans spotted during treks are born in the wild, you may also encounter semi-wild ones—those previously rehabilitated. Spotting either is a profound experience, made even more meaningful by the conservation story behind it.

Planning Your Orangutan Trekking Adventure

The ideal time to visit Bukit Lawang is every season. All treks inside Gunung Leuser National Park require a permit. Reputable tour operators will handle this for you, usually included in the trek package. Make sure your guide is officially licensed. Explore Sumatra’s Wonder will help you to plan your Orangutan trekking adventure. You can enjoy your trekking adventure in Bukit Lawang.
