if you look at spain you surely do not find much literature about multipitch climbing in southeast spain between Alicante and Almeria city.
BUT THERE IS - so I like to introduce just one of serveral places there.
I went there a few times and had the luck to climb with a "local legend" on a shady wall called Barranco del Fuerte. 21 routes wait there for you. most of them nicely bolted (plaisir bolted 6a to 7a), but still a bit alpine.
most routes can be rapelled ...
here is just one video (8 videos on the playlist and 1 how to get there)

for easier routes (5a - 6a) look my playlists for other areas in spain southeast (> "escalada xxx")
