This pic was taken on the Greek island of Kalymnos (the island in the background is Talindos) - I was there on a climbing trip just over two years ago. The shot looks like it was taken from the back of the Grande Grotta cave and I think the route is D.N.A, or one of routes adjacent to it. It really looks like this - not a photo merge, and because of the cave formation it's possible to take this kind of shot without having to climb yourself and suspend from the rope.

Great share Rich!!
