Lake Ranau is a freshwater lake on the island of Sumatra in Indonesia, located within a hilly island interior. The lake is used locally for fishing, irrigation and small-scale recreation.

Surrounding slopes and agricultural land support a mix of rural communities that rely on the lake for livelihoods. Visitor infrastructure is limited and travel typically involves regional roads from nearby towns.

The lake is a natural basin in Sumatra’s inland landscape and has been incorporated into local water management and rural economies over time.

It lies inland on Sumatra and is accessible from regional towns by local roads; the immediate landscape combines agricultural valley and wooded hills.
