Semayang Lake

Semayang Lake (Danau Semayang) is a large natural freshwater lake in Kota Bangun District, Kutai Kartanegara Regency, East Kalimantan, Indonesia. Part of the Mahakam River lake system alongside Melintang and Jempang lakes, it covers approximately 13,000 hectares. The lake is notable for its floating fishing villages, peat swamp surroundings, and as a habitat for the endangered Irrawaddy dolphin (Pesut Mahakam) and diverse freshwater fish and birdlife.

Visitors can expect a vast, calm freshwater lake surrounded by peat swamp forest and traditional stilt and floating houses of fishing communities. The setting is rural and tranquil, with wooden boats moored along the shore, fishing platforms, and open water views. Visitors can explore the lakeshore, take boat trips across the lake, observe local fishing activities, watch for freshwater dolphins and waterbirds, and experience sunset views over the water.
