It was very beautiful with some ice like formations above it and the Fossils of marine animals, sea shells can be found inside the caves and it believed is millions of year old, estimated about 30 million year of old sea fossils. There are lots of interconnected caves; some going up, some branching out.
The Arwah Cave is dark and is advisable to carry strong torch with you. The Arwah Cave is relatively new and less touristy so it is a best offbeat destination in India.
Guides are available outside the entry of the cave and Guide charges are also nominal. It is difficult to locate the fossils on your own, so guidance is needed.
