Where to See Orangutans: A Guide to Ethical Encounters

Orangutans are among the most intelligent and endangered great apes on Earth. If “seeing orangutans in the wild” is on your travel dream list, few places are as rewarding and accessible as Bukit Lawang, a riverside village on the edge of Gunung Leuser National Park (GLNP) in North Sumatra, Indonesia. This guide gives you everything you need to know for an ethical encounter—from understanding the orangutans’ status, to choosing responsible guides, and to ensuring your trip supports conservation rather than harms it.

Why Orangutans Here (and Why Ethics Matter)

• Species & status. In Bukit Lawang you’ll encounter the Sumatran orangutan (Pongo abelii), which is classified as Critically Endangered. Fewer than 15,000 are thought to survive in the wild, and their numbers continue to decline due to habitat loss, poaching, and human-wildlife conflict.
• A unique local history. Bukit Lawang once hosted the Bohorok Orangutan Rehabilitation Centre (1970s–2002). Tourism eventually made the site unsuitable for rehabilitation work, so it was closed and moved elsewhere. In 2003, a devastating flash flood destroyed much of the village, reshaping how tourism is managed today.
• Ex-captive vs wild behavior. Some orangutans here are descended from ex-captive individuals and may be more habituated to humans than truly wild orangutans. This is why strict rules exist: feeding or getting too close puts both humans and orangutans at risk of disease and conflict.

Bukit Lawang & Gunung Leuser National Park

Bukit Lawang lies about 90 km northwest of Medan, Sumatra’s capital city. Travel takes around 3–5 hours depending on traffic and weather. Private cars are fastest and most comfortable; local buses or minivans are cheaper but slower.

The village sits at the gateway of Gunung Leuser National Park, part of the UNESCO-listed Leuser Ecosystem—one of the last refuges for Sumatran orangutans, Sumatran tigers, elephants, rhinos, and countless other species. When you step into the forest from Bukit Lawang, you’re entering this vast protected area.

Ethical Orangutan-Watching Rules

These rules are non-negotiable if you want to be a responsible traveler:

1. Never feed orangutans. Feeding alters their natural behavior, causes aggression, and spreads disease.
2. Keep at least 10 meters distance. This protects both you and the orangutans. If an orangutan approaches, step back.
3. Small groups only. Ideally no more than 6–8 people, to reduce stress on wildlife.
4. Limit time with one orangutan. Maximum about one hour when observing the same animal.
5. Do not lure or block their paths. Orangutans must move freely. Never get between a mother and infant.
6. Stay away if you’re sick. Even a mild human flu can be deadly for orangutans. Some guides may recommend wearing a mask in close quarters.
7. Leave no trace. Carry out all rubbish, including fruit peels, and stick to designated trails.

By following these rules, you ensure that your presence doesn’t put pressure on an already vulnerable species.

Choosing a Responsible Trekking Operator

Not all treks are the same. To make sure your money supports ethical tourism:

• Check licensing. Certified guides who follow official park standards are a must.
• Look for rule transparency. Good guides explain the rules clearly before trekking.
• Small group policy. Six or fewer people per group is ideal.
• No “guarantees.” Ethical operators never promise orangutan sightings or offer staged encounters.
• Fair pricing. Costs should be transparent, with separate charges for park entry, guiding, and porters.

Permits, Fees, and What to Expect

• Park entry and camera fees. Gunung Leuser National Park charges entrance fees. Your operator usually arranges these.
• Trek options:
  • Day treks: Accessible and ideal for first-time visitors.
  • Overnight treks (2–3 days): Allow deeper exploration into the rainforest and camping experiences.
• Trail conditions. Expect steep, muddy, and humid terrain. Leeches are common in the rainy season, and you may cross rivers or scramble over roots.
• Return options. Many tours end with rafting or tubing down the Bohorok River back to the village.

Best Time to Visit

Bukit Lawang is equatorial—hot and humid all year.

• May to September: Drier season, easier trekking, and higher tourist numbers.
• October to April: Wetter, with muddier trails and more leeches, but the forest is lush and less crowded.

What an Ethical Trek Looks Like

• Briefing first. Guides explain safety and behavior rules.
• Quiet trekking. Small groups move calmly without shouting or calling to animals.
• Observation at distance. If an orangutan is spotted, you stop at least 10 meters away, observe briefly, then continue.
• Focus on the forest. Ethical guides highlight other species—Thomas’s leaf monkeys, gibbons, hornbills, giant trees, and medicinal plants—making it about the ecosystem, not just orangutans.

Photography Tips

• Use long zoom lenses so you don’t need to get too close.
• Never use flash, which can disturb animals.
• Avoid posting photos online that show people feeding or touching orangutans—this normalizes harmful behavior.

What to Pack

• Clothing: Lightweight long sleeves and trousers, quick-dry fabrics, rain jacket, spare socks.
• Shoes: Sturdy trail shoes with good grip; sandals for camp.
• Health: Insect repellent, personal medications, first-aid kit, sanitizer, optional mask.
• Essentials: Reusable water bottle, dry bags, headlamp, small towel, biodegradable toiletries, trash bag.
• Photography: Waterproof protection for gear, microfiber cloth.

How to Travel Responsibly

• Choose eco-conscious operators. Some donate to local schools, reforestation, or waste management.
• Spend locally. Stay in guesthouses, eat in village warungs, and buy crafts from local artisans.
• Reward good behavior. Tip guides who respect the rules and speak up about conservation.
• Write honest reviews. Share positive experiences with ethical operators and warn about harmful practices.

Frequently Asked Questions

Will I definitely see orangutans?
No. It’s a rainforest, not a zoo. Many visitors do see them, but it’s never guaranteed.

Is tubing down the river safe?
Usually yes, but it depends on recent rainfall. Always check conditions and equipment.

Are there alternatives to Bukit Lawang?
Yes—Ketambe, in Aceh, offers wilder and less touristy trekking. But Bukit Lawang remains the most accessible for first-time visitors.

Why do some orangutans come close?
Some are descendants of ex-captive orangutans or were fed in the past, making them more habituated. This is why distance and no-feeding rules are critical.
