Another Cappadocian Valley, filled with fairy chimneys and cave dwellings, with a nice inactive volcano lording over.
There was a huge multi-level cathedral carved out of the rock in the 13th century called Selime, the largest in the area. There was a whole monastery complex around it.
It was a pretty steep and gravely hike up to the top of the village with some tight squeezes and tunnels to push past, so the crowds were a bit thinner up there. That didn't stop a clever local child from attempting to extort tourist for use of the open-pit and open air turkish toilets on sight. Awkward!
