In reply to Bob Loblaw:
The Rockfax guide is really out of date, the info is nearly 10 yrs old and there has been loads of development since then. Re the David Murilla guide (Desnivel Andalucia), the maps are poor but if you use a bit of sense then it is fine, plus it covers other nearby places too (Turon, Abdulajis, Desplomilandia, Archidona, Loja + loads more). If you are just climbing in El Chorro then get the local spiral bound one from the shop in the village.
Cheers,
