Seeing orangutans in the wild is a dream for many, but not all jungle treks are created equal. Without realizing it, well-meaning travelers can end up harming the very animals they set out to admire. That’s why choosing an ethical orangutan trekking experience in Bukit Lawang is critical.
I’m obsessed with wildlife—but only where they belong: wild and free. The last thing I want is for my presence to harm them. I learned this firsthand while working in an ethical animal sanctuary in Bolivia with spider monkeys. It taught me that while some places uphold the highest ethical standards, others use the word “sanctuary” without actually putting animal welfare first—the same goes for jungle treks.
So, when planning my trip to Gunung Leuser National Park, I knew I had to dig deep to find a truly responsible trekking company. That’s when I found Green Hill.
Ethical Orangutan Trekking in Bukit Lawang: What You Need to Know
Bukit Lawang is the gateway to Gunung Leuser National Park, one of only two places left on Earth where Sumatran orangutans live in the wild. This UNESCO World Heritage site spans thousands of square kilometers of dense rainforest, rivers, and mountains—a last stronghold for critically endangered species.
Many of the orangutans here are semi-wild—a legacy of a past rehabilitation program. While they roam freely, their interactions with humans have made them more accustomed to people than fully wild populations. This makes responsible trekking even more important—how we behave affects their survival.

The Dark Side of Ethical Orangutan Trekking in Bukit Lawang: What to Avoid
Not all trekking experiences in Bukit Lawang respect the animals and the environment. Some guides prioritize tourist satisfaction over wildlife welfare, leading to harmful practices.
1. Feeding Orangutans
Feeding may seem harmless—even kind—but it’s one of the worst things humans can do. It teaches orangutans to rely on people instead of foraging, increasing their risk of starvation and deadly disease transmission. Since orangutans share 97% of their DNA with humans, illnesses like the flu can be fatal.
2. Encouraging Close Encounters for Photos
Guides often lure orangutans down from trees to please tourists looking for a close-up shot. But orangutans belong in the canopy, not on the ground. Encouraging unnatural behavior disrupts their instincts and makes them vulnerable to stress and predators.
3. Leaving Food Scraps
Food scraps left behind from tourist lunches attract not just orangutans but also macaques and other wildlife. On my trek, I saw monkeys scavenging through food scraps left by previous groups—a direct violation of park rules. This increases dependency on humans and spreads disease among species.
4. Over-tourism and Habitat Destruction
More tourists mean more impact: trampled vegetation, erosion, and habitat degradation. If we truly want to see orangutans in the wild, we need to protect their home.

Why I Chose Green Hill: A Trekking Company That Walks the Talk
Finding an ethical trekking company was non-negotiable for me. During my research, I reached out to Andrea the co-founder of Green Hill Bukit Lawang. When I asked about vegan food options, she immediately said: “Yes—100% no issue to cater for you. I am also vegan”
That’s when I knew I’d found my place.
But the more I looked into Green Hill, the more I realized how much of a difference they were making:
- Andrea worked with local authorities to create stricter guidelines for protecting orangutans.
- They rewilded palm oil plantations and turned them back into forest—including where their eco-lodge now stands.
- They retrain former hunters as trekking guides, providing alternative, sustainable incomes.
- They offer vegan food throughout the trek on request – and with a vegan owner they really know what this means!
- Their restaurant at the Green Hill lodge in Bukit Lawang is vegetarian (mostly vegan!), making them a great choice for plant-based travelers.
- They offer treks beyond the main tourist trails, allowing travelers to explore quieter, untouched parts of the jungle. This not only provides a more natural, less disruptive experience but also helps minimize human impact on orangutans and their habitat.
Green Hill isn’t just ethical—it’s actively making the world a better place for orangutans and local communities.

My Experience: Trekking With Green Hill
I chose Green Hill’s 2-Day Discovery Trek (Luxury Option) because I wanted to experience both the well-known and untouched parts of Gunung Leuser National Park—without contributing to the problem. My trek combined two different routes:
- A well-known trail where I saw orangutans from a safe distance.
- A quieter, off-the-beaten-path route, offering a more immersive jungle experience.
My guides, Ando and Roy, were strict on ethical rules, ensuring we left no trace and always kept a safe distance from wildlife.
What I Saw Firsthand on My Ethical Orangutan Trek in Bukit Lawang
Trekking deep into the rainforest was equal parts breathtaking and humbling. Towering trees, the buzz of insects, and the sheer vastness of it all made me feel like a guest in a world that belongs to the wildlife.
On the more well-traveled trail, I saw a juvenile male orangutan swinging through the canopy like an overexcited toddler, while mothers rested in their nests above, carefully watching over their babies. A true privilege to witness.
But there were stark reminders of unethical trekking. Food scraps littered the trails, attracting long-tailed macaques who had clearly learned to follow humans for leftovers. And just before we reached a viewpoint, we heard another guide had coaxed an orangutan down from the trees—exactly what responsible trekking aims to prevent.
How Green Hill Ensures Ethical Orangutan Trekking in Bukit Lawang
Unlike other groups, Green Hill actively works to protect the rainforest—not just by following the rules but by spreading awareness and educating visitors.
✔️ No feeding or luring wildlife—orangutans stay in the trees, where they belong.
✔️ A firm 10-meter distance rule—no close encounters, no exceptions.
✔️ Leave no trace—every bit of food waste was packed out, no excuses.
✔️ Supporting conservation efforts—by training ethical guides, rewilding former palm oil plantations, and educating travelers on why these rules matter.
And beyond that? It was an unforgettable trek. I got to experience the raw beauty of the rainforest, witness incredible wildlife (including those little suckers, the leeches), and cool off in a jungle waterfall before white-water rafting back to Bukit Lawang.
Of course, the rafting wasn’t without drama. Roy, our guide, fell overboard mid-rapids. He made it back into the raft, but let’s just say it was an entertaining end to the trip.

How to Choose an Ethical Orangutan Trekking Company in Bukit Lawang
If you’re planning your own ethical orangutan trekking experience in Bukit Lawang, here are must-ask questions for tour operators:
- Do you enforce the 10-meter rule for orangutans?
- What do you do if an orangutan comes too close? (Answer should be: move away.)
- How do you handle food waste on the trek?
- Do you allow feeding or touching of wildlife? (Correct answer: Absolutely not!)
If a guide hesitates or dodges these questions, walk away.
The Impact of Choosing an Ethical Trek
Booking with an ethical company isn’t just about seeing orangutans responsibly—it’s about creating real change. The more travelers demand responsible treks, the more companies will follow suit. Your choices matter.
For me, choosing Green Hill was the best decision I could have made. If you’re serious about protecting orangutans while having an unforgettable experience, they are the clear choice.
