The Madu River and its surrounding mangrove ecosystem form one of Sri Lanka’s most ecologically extraordinary and visually beautiful coastal environments. Boat safaris wind through channels of ancient mangrove forest, past tiny temple islands, feeding kingfishers, monitor lizards, and water monitors, creating a completely unexpected and deeply rewarding experience just inland from the busy south coast highway. The Bentota River offers its own distinct character – wider, calmer, and framed by coconut groves – making the combined river experience one of the region’s most memorable activities.
