As Cappadocia sits in the middle of what was once a very active volcano region it is a visually magical place with unique geological features which the tour guide will be sure to point out throughout the day. Locals carved out homes and churches hollowed out of volcanic ash all throughout Cappadocia. Even more unbelievable is the day’s second stop – the Underground city of Kaymakli. The underground city constructed of nearly 100 underground passages and tunnels has the first four floors open to tourists.
