In reply to Inhambane:
I'd say you will get a lot more from the trip if you can get confident at 6a, easy crags (as your browse has suggested) are hard to come by. A couple of the 4+ lines at
La Creveta are fantastic, but some of the other easy stuff there is poorly bolted and there are not quite as many amenable climbs as it may appear - a half days worth at most.
S'estret might be worth a visit, a few good 4s and 5s there. Not been there, but
Puig de San Marti looks promising in the right grade range. You might find enough for a day at
Cala Magraner too, plus it is an idyllic seaside location well worth seeking out.
