About Us

At Orangutan Sumatra Tour and Trek, we believe that exploring the rainforest is more than just an adventure — it’s a chance to connect with one of the world’s most precious ecosystems and make a positive impact. Our mission is simple: to provide unforgettable Orangutan Jungle Trekking experiences that are authentic, responsible, and deeply rooted in respect for both nature and the local community.

We are based in Bukit Lawang, the gateway to Gunung Leuser National Park — a UNESCO World Heritage Site and one of the last remaining habitats of the critically endangered Sumatran orangutan. When you trek with us, you’re not only stepping into a lush, vibrant jungle filled with wildlife, but also joining a movement to protect it.

Our Way of Trekking

We believe that the way you walk through the rainforest matters just as much as the path you take. Our Orangutan Jungle Trekking philosophy is built on moving gently, learning deeply, and leaving the forest just as wild as we found it.

When you join us, your journey will follow three guiding principles:

1. Wildlife First – We watch orangutans and other animals in their natural behavior, without disturbing them. No feeding, no touching — just quiet observation and patience, allowing you to witness moments that feel truly wild.

2. Nature Left Untouched – We follow established trails, carry out all our waste, and avoid anything that could damage the delicate balance of the rainforest.

3. Stories and Knowledge – Our local guides share not only the wonders of the jungle, but also the traditions, plants, and legends that connect people to this forest. Your trek becomes a living classroom, full of insight and wonder.

This approach creates an experience that is richer, calmer, and far more rewarding than simply “ticking off” a sighting.

Led by Locals, Powered by Purpose

Our guides aren’t just professionals — they are guardians of the jungle. All of them grew up in Bukit Lawang and have been exploring these trails since childhood. They know where the hornbills like to perch at sunrise, where medicinal plants grow, and how to track the sound of gibbons calling through the canopy.

By hiring only local guides and porters, we ensure that your trekking fees stay within the community, directly supporting families and preserving local traditions. In addition, every trek contributes to education programs for village children and provides financial assistance to single mothers, helping create opportunities where they are needed most.

Sustainable by Nature

We take sustainability seriously — not as an optional extra, but as a core part of our identity. Our Orangutan Jungle Trekking experiences are designed to have as little impact on the environment as possible. This includes:

• Using reusable water bottles and eco-friendly food containers

• Avoiding single-use plastics entirely

• Limiting group sizes to minimize disturbance to wildlife

• Properly disposing of all waste or carrying it back out of the forest

• Choosing natural materials and local produce whenever possible

By keeping our treks small-scale and low-impact, we create a more intimate experience for you while protecting the very environment you’ve come to see.

When You Trek With Us, You Make a Difference

Your journey has a ripple effect. We donate 10% of our profits directly to local education projects and women’s empowerment initiatives in Bukit Lawang. This means that every step you take in the jungle also supports the people who live alongside it.

Conservation is not just about protecting wildlife — it’s about creating harmony between people and nature. By choosing us, you help ensure that both the forest and the community can thrive together.

Join the Movement — Trek with Purpose

Travel is powerful. It has the ability to inspire change, to break down barriers, and to open hearts. At Orangutan Sumatra Tour and Trek, we believe that travel should give back more than it takes.

When you choose our Orangutan Jungle Trekking tours, you become part of a bigger story — one that values conservation over exploitation, respect over convenience, and meaningful experiences over rushed checklists.

The rainforest is calling. Let’s explore it the right way — together.
