Yeah, they are very neat. The vertical walls on the west side have lots of cracks too and look climbable. But I could find no info about any technical climbing so I think either a) the limestone is too fragile to hold protection or b) it's not allowed as they want to keep it pristine. (I'll submit more photos of the big walls there soon! :- ) )
