In reply to timmyhobby:
Cala barques is really, really excellent, even just to spectate! You only need two pairs of shoes and a tiny bit of chalk. Diablo is something else, its best left to calm days in september as you will be spending a lot of time in the water, which is when the sea is at its warmest. The traverse into where the routes start at diablo is a feat in its own right, 150m of climbing up to f6b at points. If you do go to diablo try to bring a dingy. Cala marcal is also good but not worth a big detour.
