Tudugala Falls is one of the most popular waterfalls in Kalutara. In the reserve, Tudugala flows like a giant, lifting the biodiversity of Tudugala, pushing the great body of water to the edge of the river, breaking into three parts, sometimes innocently flooding the reserve.
This waterfall can be reached by taking the Kalutara - Matugama road towards Kalutara for about 3 km and turning right at the Tudugala junction for about 4 km. A small footpath runs in the middle of a rubber plantation near a dilapidated building now believed to belong to a white gentleman who lived in the past. If it's a crowded day, you can hear the sound of people playing bongos at the bottom of the waterfall in the middle of the footpath.
