Covarrubias-Mamblas-Puentedura-Covarrubias

Leave Covarrubias and climb towards the hermitage of Mamblas. Before reaching it, take the path that circles around the Castillejo. Along the high Sierra de Mamblas, parallel to the road to Soria, continue until you take a left descent to reach the Mecerreyes-Cuevas road between juniper bushes. Cross the road and continue on a very wide track, passing a small abandoned village and then a pig farm. Descend on a wide, though quite gravelly, track towards Puentedura. Cross the road and the Arlanza River, and on the left take a track that leads to the hermitage of Redonda, finally accessing Covarrubias through the El Arrabal neighborhood.
