Top Orangutan Sanctuaries in Indonesia You Need to Visit
If you’re planning an unforgettable wildlife experience in 2025, here are the top orangutan sanctuaries in Indonesia you need to visit, with Bukit Lawang topping the list for its unrivaled access to the Gunung Leuser rainforest and authentic jungle experiences.
1. Bukit Lawang – North Sumatra (Gunung Leuser National Park)
The #1 Orangutan Sanctuary in Indonesia for 2025
Location: Gunung Leuser National Park, North Sumatra
Species: Sumatran Orangutan (Pongo abelii)
Best Time to Visit: May to September
Bukit Lawang is hands down the best orangutan sanctuary in Indonesia and a dream destination for eco-tourists in 2025. Nestled on the edge of Gunung Leuser National Park—a UNESCO Biosphere Reserve—Bukit Lawang offers travelers the rare opportunity to see critically endangered Sumatran orangutans in their natural habitat.
Once a rehabilitation center, Bukit Lawang is now a prime eco-tourism hub. Guided treks through the dense rainforest give visitors a front-row seat to orangutans swinging freely through the canopy, often accompanied by long-tailed macaques, hornbills, and the occasional Thomas Leaf monkey.

- Direct support to conservation efforts
- Unique chance to observe semi-wild and wild orangutans

2. Tanjung Puting National Park – Central Kalimantan, Borneo
The Original Orangutan River Safari
Location: Central Kalimantan, Borneo
Famous For: Houseboat river cruises through orangutan habitat
Species: Bornean Orangutan (Pongo pygmaeus)
Tanjung Puting National Park is perhaps the most iconic orangutan destination in Indonesia. It’s where legendary primatologist Dr. Biruté Galdikas conducted groundbreaking research and where visitors can float down the Sekonyer River on traditional klotok boats for a chance to encounter orangutans up close.
You’ll visit feeding stations at camps like Camp Leakey, one of the most important orangutan research and rehabilitation centers in the world.

3. Sebangau National Park – Central Kalimantan
The Hidden Gem of Kalimantan’s Peat Swamp Forests
Location: Palangkaraya, Central Kalimantan
Species: Bornean Orangutan
Highlight: Wild orangutans in a remote, untouristed area
Unlike the more touristy Tanjung Puting, Sebangau National Park offers a chance to witness fully wild orangutans in their untouched habitat. This massive peat swamp forest is a vital carbon sink and home to one of the largest populations of Bornean orangutans.
Because it’s less developed for tourism, wildlife sightings here feel raw and rewarding. Guided treks or canoe rides through blackwater rivers provide the chance to spot orangutans along with gibbons, sun bears, and over 150 species of birds.
Why Visit Sebangau in 2025?
- One of the best off-the-beaten-track wildlife sanctuaries
- Supports grassroots conservation and indigenous communities

- Less tourist traffic = more intimate jungle experience
If you’re a serious wildlife enthusiast or conservationist, Sebangau will capture your heart.
4. Kutai National Park – East Kalimantan, Borneo
A Remote Haven for Wild Orangutans
Location: East Kalimantan, near Bontang
Experience: Jungle hikes and orangutan tracking
Species: Bornean Orangutan
Kutai National Park is a lesser-known but critically important conservation area. Home to over 600 wild orangutans, the park’s swamp forests and dry lowlands offer some of the most natural orangutan sightings in Indonesia.
The visitor experience is more rugged compared to Tanjung Puting or Bukit Lawang, but that’s part of the appeal for adventurous travelers.
Why Visit Kutai in 2025?
- Chance to spot fully wild orangutans (no feeding stations)
- Far fewer tourists for a rawer wildlife experience
- Supports important reforestation and anti-logging efforts
- Accessible from Samarinda or Balikpapan
If you’re craving an orangutan encounter far away from crowds, Kutai should be on your radar for 2025.
5. Jantho Forest – Aceh, Northern Sumatra
A Remote Sumatran Conservation Stronghold

Managed By: Sumatran Orangutan Conservation Programme (SOCP)
Jantho Forest is one of the newest release sites for orangutans rescued from captivity or conflict. Managed by SOCP, the sanctuary operates as a soft-release site, where orangutans are slowly reintroduced into the wild under close monitoring.
