We arrived at the monastery about half an hour after closing time so I can't comment about what's inside. We knew it closed quite early (unfortunately) but wanted to avoid walking in the afternoon heat. Nevertheless, we enjoyed finding our way in a map along the macadam road leading through the forests and then walking from the little improvised parking...
This place is mentiont in every guide as if it was something really special. I don't know, it's just a house in the middle of rocks. But my parents liked it.
You can't access it by car, so you have to walk for about 2 hours - the walk was more interesting than the old monastery.
