Lake Kutubu, Protected wetland lake in Southern Highlands Province, Papua New Guinea.
Lake Kutubu is a protected wetland covering more than 4,900 hectares in the Southern Highlands of Papua New Guinea. The water body sits at roughly 800 meters elevation and is surrounded by limestone formations that shape its distinctive geology.
The region remained isolated for many decades, accessible only by light aircraft and foot travel before infrastructure development. Recent projects created new roads and regular flights, fundamentally changing how people reach this remote location.
The Foe and Fasu people live in villages around the lake and continue using traditional farming methods passed down through generations. Visitors encounter communities whose daily lives remain closely tied to the water and surrounding forests.
The lake is best visited during drier months when travel conditions are more stable across the region. Visitors should prepare for basic accommodations and limited services, as the area remains remote despite recent access improvements.
The lake is home to ten fish species that exist nowhere else on Earth, found only in its waters. The protected area also contains roughly 1,000 hectares of swamp forest that forms a critical part of this ecosystem.
