Ruhunukanda Forest Reserve is located in the Kalutara district and has a high level of biodiversity.

The forest is home to a variety of birds, reptiles, insect species, toad species, mammals and very rare species of butterflies. The Maguru River flows through the forest of the Ruhunu Hills, adding to its appeal. This is called an evergreen rain forest. Ruhunukanda forest is home to 52 different bird species. The period from December to March has been identified as the best time to visit the Ruhunu Kanda ecosystem. The reason is the decrease in rainfall during that period.
