As I mentioned earlier, the place is very humid and warm. There are places in the caves, which are very narrow and you have to squeeze through. There is also a place where you see a small natural waterfall inside the cave which called "Patala Ganga". Its amazing to see how much work AP tourism has done on the caves to make it easy for tourists to come and visit with safety in place. There was a warning sign in the entrance that said "In case of power failure, don’t move and try to stay under one of the exhaust opening". However there is generator backup. When we were inside, the power did go, but in less than 10 seconds the generators came up.
