In reply to jackdimples1: not many crags in Costa you can rig from the top. So you lead and rig. Lots of people climbing so I always try and move my group about, it means I have to climb the route to rig it and then climb it again to derig it, but it works fine as some venues the easy routes are very short.
Loads of easy single pitch stuff. Get the Rockfax guide to Costa blanca and you will be able to see how to get to the crags and the spread of grades.
Toix, Ganda, alcalali, echo 1.5, sella, some good crags to the north beyond Ganda as well the Aventador and one by it, plus another by a castle. Plus some nice stuff in Guadalest.
I have to say th ar more and more groups heading out there now, which I think is a good thing. But I would hate for the issues of places like stanage popular end to happen on the easy crags out there where they are almost over run by groups top roping. See my intro about moving about.
