Inside the dark cave, the ageless limestone formations that pops out from the floors, cave-walls and ceilings elegantly decorate the whole structure. These peculiar formations are really hard to believe whether manually sculptured or not! But they only add up the fact that nature is the ultimate artist. This cave also houses some wild species that are too rare to be seen. (As it is too pristine, special permission is needed to visit Dark caves).

What makes a major difference here from a manmade Cathedral may be the rush of macaque monkeys, a brigade of their own.

Besides the major shrine of Lord Subramaniya, few other shrines can also be seen here wonderfully complimenting the Dravidian temple architectural style something that can't be seen outside South India.
