Klias Wetlands

Klias Wetlands is a large mangrove and nipa palm wetland system along the Klias River in Beaufort District, Sabah, on the Klias Peninsula in western Sabah. It is notable as a protected wetland ecosystem known for river cruises that offer sightings of proboscis monkeys, long-tailed macaques, diverse birdlife and evening firefly displays. The area features tidal river channels, mangrove forests and traditional riverside villages, making it a key nature-based attraction near Kota Kinabalu.

Visitors can expect a guided river cruise through tidal mangrove and nipa palm channels of the Klias River. The setting is a lowland wetland with dense mangrove forest, riverbanks and small fishing villages. Cruises typically depart in the late afternoon for wildlife viewing, including proboscis monkeys, long-tailed macaques, monitor lizards and birds, followed by an evening firefly watching experience after sunset. Facilities are centered at the river jetty with boats and a visitor area.

Klias Wetlands forms part of the Klias Peninsula, one of the largest remaining mangrove and peat swamp areas in Sabah. The wetlands have long supported traditional fishing and riverside communities and have been recognized for conservation due to their importance as habitat for proboscis monkeys and as a representative mangrove wetland ecosystem in western Sabah.

The wetlands are associated with local Bisaya and Brunei Malay riverside communities who traditionally depend on fishing and nipa palm harvesting. The river landscape and firefly displays hold local cultural value and are presented to visitors as part of community-based nature tourism in Beaufort District.
