Lake Towuti is the largest lake in Sulawesi and the second-largest lake in Indonesia, located in Towuti District, East Luwu Regency, South Sulawesi. Part of the ancient Malili lake system, it covers about 561 square kilometers and is known as a tectonic lake estimated to be millions of years old. The lake is notable for its clear freshwater, surrounding forested hills, endemic aquatic species, and islands such as Pulau Loeha.

Visitors can view expansive open water, islands within the lake including Pulau Loeha, and calm bays used for boating and fishing. The area is relatively remote and natural, with simple visitor facilities and opportunities for sightseeing, photography, and boat trips on the lake.

Lake Towuti is part of the Malili lake system, an ancient tectonic lake system estimated to be 1 to 4 million years old, making it one of the oldest lake systems in Indonesia. Its long geological isolation has made it significant for scientific research on evolution, geology and limnology.

The lake supports lakeside communities in Towuti District whose livelihoods depend on fishing, small-scale agriculture and boat transport. It is an important local resource for daily life, fishing traditions and community activities for villages around its shores.
