There is very popular folklore attached to this cave which goes something like this. When a cow grazing on the top of the caves fell through a hole in the roof, the herdsman while searching for the cow came across the caves. On finding a stone resembling Shiva Lingam in the caves, a small temple devoted to Lord Shiva was built outside it. These caves are currently home to animals like golden geckos and bats.
