Kutai National Park

Kutai National Park (Taman Nasional Kutai) is a 1,986 km² protected area in East Kalimantan, straddling the districts of Kutai Kartanegara and East Kutai. Originally established as a game reserve in 1936, it was declared a national park in 1982. The park protects lowland dipterocarp rainforest, freshwater swamp forest, and heath forest — some of the most threatened ecosystems in Borneo. The park lies adjacent to the Mahakam River, the lifeblood of East Kalimantan.

Kutai National Park is renowned for its wild orangutan population — an estimated 600–750 individuals live within its boundaries. It also hosts proboscis monkeys, gibbons, sun bears, sambar deer, and over 300 bird species. The park's proximity to the industrial areas of Bontang and Sangatta has created significant conservation challenges from logging, mining, and palm oil expansion, but the core area remains well-protected.

The climate is wet tropical with average temperatures of 25–33°C year-round. The rainy season runs November–April, with the driest months being June–September. The park is accessible throughout the year, though some trails become muddy and difficult during the heaviest rains.

By Plane

The closest major airport is Sultan Aji Muhammad Sulaiman International Airport (BPN) in Balikpapan, about 150 km south of the park. From there, a 3–4 hour drive via Bontang brings you to the park entrance. Bontang Airport (BXT) serves small aircraft from Balikpapan, reducing road travel to about 30 minutes.

By Car / Road

From Balikpapan, the route to the park's main gate near Bontang is along a well-paved road (about 3 hours). Public minibuses from Balikpapan's Batu Ampar terminal to Bontang (Rp 80,000–100,000) run regularly. From Bontang, an ojek or taxi to the park entrance costs about Rp 50,000–100,000.

The main trails in Kutai National Park are accessible on foot from the Sangkima area, the primary visitor access point. River transport on the Mahakam River is also common for reaching the park's southern sections. A guide can be arranged through the park office at Sangkima.

Small warung at the Sangkima entrance serve simple Indonesian meals — nasi goreng, mie goreng, and gado-gado — for around Rp 20,000–40,000. Bontang has a wider selection of restaurants serving Indonesian and seafood dishes. Bring your own drinking water and snacks.
