There are two waterfalls in the Ella area. The most popular being the waterfall at the Bandarawela – Wellawaya Road. This is popularly known by the name of Ravana Ella by the tourists as well as the villagers around. There is another waterfall above this falls which is not visible to the main road which is also called Ravana Falls. This is generally considered the real Ravana Falls due the close proximity of the cave which is considered a place there Sita (in Ramayana) has hidden by the Lankan King Ravana for a while.

The correct name of the waterfall by the road is said to be “Bambaragama Ella“.

This Ravana Fall (proper) is 25 meters high and flows from the Bandarawela Hill Oya Reservoir. During the dry season this almost dries up but during the rains flows at full force. Therefore the best time to visit this falls is during the rainy season or just after.
