Pulau Bakut

Pulau Bakut is a small Nature Tourism Park (Taman Wisata Alam) of about 0.18 km² (roughly 18 hectares) on a river island in the Barito River of South Kalimantan, Indonesia, in Barito Kuala Regency about 15 km from Banjarmasin, situated beneath the landmark Barito Bridge. ^[1] Designated a tourism park in 2003 under Ministry of Forestry Decree No. 140/Kpts-II/2003, it is known as a refuge for the endangered proboscis monkey and protects mangrove and riverine forest. Despite its tiny size, it is a popular and accessible wildlife site managed by BKSDA South Kalimantan, offering a close-up look at Borneo's distinctive estuarine primates.

Pulau Bakut is best known for hosting proboscis monkeys, the long-nosed primate endemic to Borneo, which feed and rest in its riverside trees. Long-tailed macaques, silvered langurs, monitor lizards, and various birds such as kingfishers and herons also inhabit the island and surrounding waters. ^[1] The small island serves as a concentrated and easily reached place to observe proboscis monkeys, complementing nearby Barito sanctuaries in conserving the species.

The island is covered by mangrove and freshwater swamp forest, including rambai (Sonneratia), jingah, putat, and other tidal-tolerant trees that provide essential food for proboscis monkeys, along with nipa palm and riverine shrubs. ^[1] The vegetation is adapted to regular tidal flooding from the Barito. This mangrove-dominated forest forms the habitat backbone that sustains the island's primates and birdlife.

Pulau Bakut is a low, flat alluvial island formed from sediments carried by the Barito River in its tidal reaches, with soft, waterlogged soils lying just above water level. The Barito Bridge spans the river above the island, linking the city to the western bank. Daily tides and seasonal floods shape the island's shores within the dynamic lower-Barito environment.

The island has a hot, humid tropical climate with average temperatures around 27–28°C and average annual rainfall of about 2,185 mm, with the heaviest rainfall during the northwest monsoon from roughly November to April. ^[1] Tidal cycles influence water levels and boat access. Consistent high humidity characterizes the riverine mangrove setting throughout the year.

Lying on the Barito within the Banjar riverine cultural region, Pulau Bakut sits in a landscape long shaped by fishing, river trade, and tidal agriculture around Banjarmasin and Barito Kuala. The construction of the Barito Bridge brought the area into greater prominence, and the island's protection as a tourism park reflects efforts to conserve proboscis monkeys near a busy transport corridor. Local communities along the river have historically depended on the delta's resources.

Pulau Bakut was designated a Nature Tourism Park in 2003 under Ministry of Forestry Decree No. 140/Kpts-II/2003, and its role as a monitoring site for the proboscis monkey was affirmed in 2012 under BKSDA Decree No. SK. 1653/IV-K.23/KKH/2012. ^[1] It is managed by BKSDA South Kalimantan. The taman wisata alam status reflects growing attention to conserving accessible proboscis monkey habitat in the Barito and developing responsible wildlife tourism beneath the iconic bridge.

The main draw is observing proboscis monkeys and other primates along short ironwood boardwalks and forest paths, often viewed in the early morning or late afternoon when the monkeys are active near the water. ^[1] The island also offers mangrove scenery and views of the Barito Bridge. Its compact size allows a short, rewarding visit focused on wildlife and the riverine environment.

Access is by kelotok (traditional boat) from Banjarmasin or nearby river landings, about 15 km from the city center and reachable near the Barito Bridge crossing. ^[1] Facilities include ironwood walkways and visitor areas designed to minimize disturbance to wildlife. Visits are typically arranged with local operators or coordinated through BKSDA South Kalimantan, taking advantage of the island's convenient location.

Conservation focuses on protecting the proboscis monkey and its mangrove habitat on a small island under pressure from nearby development, river traffic, and tourism. Maintaining the rambai mangrove food source, limiting disturbance, and managing visitor behavior are priorities. BKSDA South Kalimantan works to keep Pulau Bakut a secure refuge for the species while supporting low-impact tourism and public awareness about Borneo's threatened estuarine wildlife. ^[1]
