In reply to chrismcd23:
A lot depends when you are going and whether you can tolerate the sun (July August).
The climbing near Motril (Los Vados) is good and you can climb out of the sun in places until late morning at Sector Canal. Most other cliffs are in the sun in the morning. To enjoy Motril you need to be climbing 6a+ to get much done. There are also some multi pitch routes.
Los Cahoros near Monachil is a gorge with a variety of grades and aspects, worth the extra drive if you have time.
If you want some easier climbs or somewhere different, there is plenty of stuff to be done near Orgiva. Also in a gorge so you can get shade. A few crags are listed on our website:
