Near Murillo de Gállego
ACCESS: From Murillo you will have access to the southern and western iron paths. Take the turn-off towards Agüero and keep on this road for two kilometres, where you turn off to the right. Continue on the earth track for a kilometre and a half. Then turn off to the right. After crossing the gorge, a few metres on, leave your car. From there, there are 20 minutes on foot on a sign-boarded path which will take you to the wall.
ITINERARY: Once at the foot of the Ruaba Crag, for the southern iron path, take a path off to the right sign-boarded with red and yellow triangles as far as the first section of chains.For the western iron pathway, the access is more complicated. You turn off to the left passing under the big ceiling of the Calva Cave and reaching the slope on the other side of the gorge. Cross over the Varella Portillo pass on the lower part and, with the spur and crest gap in view, walk towards a large stone quarry until you come to the first clamps and chains.
