Terradets is a very impressive gorge in the Serra del Montsec 40km or so North of Balaguer. Amongst the many big walls is the single pitch sport crag, Paret de les Bruixes. A very steep overhanging wall of tightly knitted tufas, it gives superb, albeit hard climbing, that requires good stamina. Grade 7b upwards is the focus here. There a few "easier" 6b to 7a routes, but are now so polished as result of being used as a warm up, that they are not worth a visit in their own right. The crag gets the sun in the afternoon, how soon depends on the steepness of the route you are trying!
