A short distance north of the centre of Petrer/Elda is 'the tower of the raven', set high above the valley, with a difficult-to-spot black metal cross on its summit. This west-facing cliff is home to twenty worthwhile climbs, several of which are in the lower grades. The routes are up to 30m in length, often of two pitches, and are well bolted. The rock is generally less than vertical and many of the routes finish on a true summit. The place is well worth a day if you are in the area and climb at the appropriate grade. The cliff is also known as Espolón de la Sierra del Caballo. The climbing here was first developed in the early 1960s.
