Kutai National Park, Protected rainforest reserve in East Kalimantan, Indonesia.

Kutai National Park is a rainforest reserve in East Kalimantan that covers a large tropical lowland area with rivers running through it. The terrain includes swampy zones and slightly higher ground, all filled with dense vegetation and varied wildlife.

The site was first protected as a game reserve in the 1970s to counter heavy logging activity. Conversion to national park status in the early 1980s marked a stronger commitment to forest preservation.

The park sits next to traditional Bugis settlements where local communities live by practices passed down through generations. These people maintain close ties with the forest and its resources.

The visitor station at Sangkima is reachable by car and offers accommodation along with walking trails through the forest. An alternative is arriving by boat along the Sangatta River, which provides a different way to experience the area.

The elevated boardwalk at Sangkima leads to what was one of the largest trees recorded in the park; the loop track passes old national park buildings. The park also counts 41 orchid species and 220 species of medicinal plants among its 958 flora species.
