A humid evening settles over Sabah as the minivan leaves Kota Kinabalu’s harbor lights behind and the road narrows toward the Klias wetlands. You board a shallow-draft river boat where the river’s slow current nudges the hull and the mangrove roots lean in like curious spectators. As darkness deepens, trunks and twigs begin to spark—thousands of fireflies flashing in sync along the riverbank, turning the mangrove corridor into a living string of lanterns.
Verified experiences and guided adventures in the surrounding area.

A humid evening settles over Sabah as the minivan leaves Kota Kinabalu’s harbor lights behind and the road narrows toward the Klias wetlands. You board a shallow-draft river boat where the river’s slow current nudges the hull and the mangrove roots lean in like curious spectators. As darkness deepens, trunks and twigs begin to spark—thousands of fireflies flashing in sync along the riverbank, turning the mangrove corridor into a living string of lanterns.
The area sits on low coastal plains carved by sediment from inland rivers; these mangroves are young in geological terms but centuries-deep in cultural ties. Local Bajau and Dusun communities have relied on the river for fish, transport and seasonal salt production. The tour pairs a daytime sweep of Kota Kinabalu—floating mosque views, market stalls, and post-colonial architecture—with an evening wildlife focus, offering context on local ecology from guides who know the river rhythms.
Expect slow, quiet cruising in search of firefly clusters and optional sightings of proboscis monkeys, kingfishers, and egrets. Photography requires a steady hand and long exposure settings; the guides manage close approaches so boats don’t disturb colonies.
Practical notes: the round trip from Kota Kinabalu takes most of the day into night, with transfers in air-conditioned vehicles and a buffet dinner after the first cruise. Bring insect repellent, a compact rain jacket, and a charged camera battery; reduce white light on the river to protect the insects. The experience is low-impact but dependent on weather and river levels—book in advance and arrive ready to sit quietly and listen.
easy.

Common sightings include proboscis monkeys, long-tailed macaques, egrets, kingfishers and occasionally otters near the mangrove edge.
Yes, but use a tripod, long exposure settings and avoid flash or powerful torches; the guides can position boats for better framing while minimizing disturbance.
The Klias wetlands have long supported local Bajau and Dusun fishing communities; the river was historically a transport link between interior settlements and coastal markets.
Firefly populations are sensitive to light pollution and habitat loss—operators typically avoid bright lights and follow quiet-boat protocols to minimize disturbance.
