In reply to jonhowson:
Montserrat looks like epic fun. Catalunya has all sorts of adventures but I suspect it will be too cold.
I'd probably just go el chorro if I wanted it nice and easy. I.e minimal driving, minimal fuss. Loads of single and multipitch.
There is costa blanca too, but lots more driving. Not done that much multipitch there, but if you do go, make sure you go south to leyva to climb the stunning 150m main wall. Its brilliant and really well bolted on most of the routes.
