Where is the original entrance to the cave I wonder - & how far back does it go: I hear there was a roof fall years ago so you can't explore all the way to the end?
Ive been in, Id be thinking this is the original entrance but couldnt be sure. It looks as if the entrance was modified with the reused ogham lintel etc.
I don't know about a rock fall - Im no pot-holer but I did see some of the graffitti including the bit by Irelands first President Douglas Hyde.
