Covarrubias-Puentedura-Lerma-Tordueles-Covarrubias

Starting from Covarrubias, cross the bridge over the Arlanza River towards Retuerta. Just after crossing the bridge, turn left into Arrabal and take the track leading to the Redonda Hermitage. Continue along a tree-lined path with a short climb and descent down to Puentedura. Cross the bridge and turn left onto the road to Lerma; after climbing, at 500 meters turn right onto a path. Continue with ups and downs until reaching Quintanilla del Agua. Join the road to Lerma, cross Quintanilla, and take the left turn onto the road to Tordueles. Just after crossing the bridge, take the dirt track on your right. Follow it, passing near the Bascones farm, and in the distance glimpse the Parador de Lerma on the hilltop. Proceed on flat terrain and finish with a short climb to the Parador de Lerma. Return by the same route, passing Bascones farm, reaching the junction with the road to Tordueles, turn right, and by road arrive at and cross Tordueles. Continue on the road to Puentedura, then turn right to cross the village and connect with the path leading back to Covarrubias via the Redonda Hermitage.

The route is flat and easy, but be careful with the wind — when it blows, it really blows!
