Incredible! Has to be seen to be believed. I am glad I toured Derinkuyu Underground Museum even though I consider myself somewhat claustrophobic. I was very relieved to have a private guide for the cave tour, as being stuck in a large group could have been uncomfortable. While coming up a long, narrow, low, tunnel, that was the only way in, and out; there were a couple of other visitors sweating profusely and breathing heavy and it occurred to me, if they collapsed on the stairs everyone deeper in the cave would be trapped.
