Prevab Mentoko: A Hidden Treasure in the Heart of Kutai National Park

Imagine starting a journey into the depths of Borneo’s rainforest—where city noise fades, Wi-Fi disappears, and all that’s left is the symphony of birds, insects, and swaying trees. Welcome to Prevab Mentoko, a hidden gem in East Kalimantan’s Kutai National Park, and one of the highlights of the Borneo Local Journey experience.
This isn’t your typical tourist trail. It’s the kind of place where you don’t just visit nature—you feel it, breathe it, and walk in rhythm with it. With giant trees lining your path and the possibility of spotting a wild orangutan overhead, this journey becomes more than just travel—it becomes connection.
Camp Kakap: The Heartbeat of the Forest

Facilities include:
- 10 basic rooms for researchers, students, and eco-minded guests
- A quiet prayer room (mushola)
- Two clean, functioning toilets
- A shared kitchen and forest-view dining area
Don’t expect five-star luxury. Expect something better: an authentic jungle journey.
A Journey Through Science and Discovery

A quick timeline of the journey so far:
- 1969–1970: Early fieldwork by American scientists from the University of Washington and UC
- 1980s: Japanese researchers joined the journey, expanding insights into orangutan behavior, diet, and social life
- Today: Local scientists, students, and conservationists carry on the legacy
Contributions that matter:
- Deep understanding of orangutan parenting, communication, and foraging
- Data that informs global conservation strategies
- Real-world training for young scientists and local leaders
This is a place where knowledge is grown, shared, and passed on—generation to generation. And many current park guides began their journey as student researchers here.
Not for Mass Tourism—And That’s the Point
Prevab is not about crowds or commercial tours. It’s a restricted conservation zone, managed by Kutai National Park Authority (Balai TNK), where only responsible, low-impact journeys are allowed.
Activities permitted:
- Scientific research
- Environmental education
- Small-group ecotourism (only with licensed guides)
Every visit must be pre-approved and guided—ensuring that the forest stays protected for future generations of both humans and wildlife.
