An interesting detour from Empalme del Valle will take you past Vadillo Castril village to the Puente de las Herrerías bridge (7km) and then 11km on southward by unpaved road to the Guadalquivir’s source.
From here you can, if you like, continue a further 9km east then south (unpaved) to Cabañas, which, at 2027m, is one of the highest peaks in the park (it's a 3km round-trip walk of about 1½ hours from the road to the summit and back). Or you can head west then north back to Cazorla (26km) via the Puerto Lorente pass, on unpaved roads most of the way.
