Overview
The Kalu Ganga (Black River) flows from the Ratnapura highlands through the Sabaragamuwa Province before emptying into the Indian Ocean near Kalutara, creating one of the most productive river estuaries on the western coast. The river mouth and its flanking mangrove system are a haven for waterbirds, and the traditional fishing communities that use both the river and the lagoon create an authentic maritime cultural landscape. The combination of the river’s highland connection (it passes near the Sinharaja rainforest’s water catchment) with its coastal estuary ecology creates a biological richness that extends far beyond what a coastal observer might expect. The Kalutara Bodhi Temple on the river bank and the sweeping river mouth view make this a site combining natural, cultural, and spiritual heritage.
