Found lots of drilling, chipping, sika courtesy of the guy who ran the refugio when we were there, but saying that loads of good quality routes too. Quite a lot of pocket pulling but quite friendlly. Far from the best place I've been to in Spain though, but we found it good as you can get to most crags without needing a car.
We were there in march and it was baltic cold in the shade, but OK in the sun. crags face all directions. No idea on guides and route names, we just scribbled topos out of guide in refuge each day.
