Some info on Rodellar here http://ukbouldering.com/board/index.php/topic,4236.0.html . I went there for two months last year and for me it is easily my favourite sport climbing area. There are some pics from that trip here http://www.facebook.com/album.php?aid=27746&id=722433792This is one of the main sectors - The Gran Boveda, it varies from 20-35m and has loads of super classic steep tufa routes, mostly in the 7b-8b+ range.If you like really long, really steep routes, on mostly big holds sector Surgencia is unsurpassable. Here's a pic of the classic 40m 8a El Corridor De La Muerta: Rodellar may well be in great nick at the end of Feb, but it probably more prone to seepage than the other crags mentioned and the best sectors are more shady. If the worst comes to the worst there are still a couple of weeks worth of routes which never get wet. For non-tent accomodation the El Puente campsite just outside the village has chalets and apartments and does off season discounts for climbers. Terradets has a good cheap refugio very near the crag and a mid priced hotel a little further north. Montgrony has a refugio in a very beautiful old monastic sanctuary building, right beneath the crag. There is a downloadable topo for Montgrony on Rockfax.comHere's a pic of a 7a+ at Montgrony:
