This beautiful and symmetric prototype of shield volcanoes is very prominent from the Parliamentary Plains and also the southern part of the Kaldidalur Route. This 1060 m high volcano was created at the end of or shortly after the end of the last cold epoch of the ice age.

Its lava fields and the whole surrounding landscapes have been scarred with faults and fissures by the tectonic movements of the area. The crater on top of the mountain is about 500 m wide.
