Göreme Open Air Museum. The museum has a collection of caves and fairy chimneys. Be sure to visit the church in a cave across the highway outside the museum entrance, whıch is included in museum admission (save your ticket). The museum is very small and repetitive (church next to church next to church). Some have nice frescos, but other have geometric motifs that can be seen for free in the chimneys across the street (easy hike). 15 YTL, 8 YTL extra for the Dark Church.
