Dehena waterfalls on the road to Wewalwaththe from Rathnapura, Sri Lanka.

The Dehena waterfall is by the side of the main road from Rathnapura to Wewalwaththe. During heavy downpours it occassionally makes the road impassable. There is a pool built at the base of the waterfall for bathers. The water from the Adam's Peak wilderness, feeds this waterfall.
