Kalutara boasts beaches not only along the seashore but also along the fresh waters of the Kalu Ganga river. The riverside beach offers pleasant hotel rates and provides a water sports experience that is only slightly less extensive than the primary tourist area by the seaside.
The most acclaimed beaches in Kalutara are situated along the seashore. This expansive coastal stretch, sometimes reaching widths of up to 25 meters, is adorned with lush tropical vegetation. The sand is coarse and consistently warm, but the shoreline has a steep slope into the water, making it advisable to swim only in calm weather.
