Roque de Taborno, Anaga, Tenerife 

It's an outstanding area on the island. Unfortunately I didn't climb all the way to the top, but at least I've tried partially - we were quite late and had to move on to return to the car before it got too dark to wander around. Anyhow, It seem to be quite challenging to climb up there. I've seen some crazy older guy climbing down frontally from the top, like it's nothing, hehe :D fortunately he was okay
