Let's get one thing out of the way. Cappadocia is everything they say it is and more. There is enough here to keep one occupied for a week, but unfortunately I only had two days, so everything got a bit compressed. I did, however, have a car, so that was a major convenience factor - highly recommended for anyone short on time in this place.
It's probably easiest to introduce Cappadocia with photos, because it's impossible to do justice to the surreal scenes here with mere words. Short note on how the cone-like "fairy chimneys" i.e. unique rock formations were formed: Volcanic activity millions of years ago deposited layers of ash (of varying hardness and density) all over the region here. The weathering effects of wind and water over the next million-over years chiseled away at the softer layers, leaving behind the "columns" which we see today.
Some photos from my walkabouts and drive-abouts:
See how caves are carved directly into the rock face?
