The road that borders the Arlanzón reservoir has an incredible perspective of the mountains as a backdrop. The clouds are reflected in the water and the views in general give meaning to cycling in these remote places.

It is a route along a marked path (for hiking or biking) that was the layout of an old mining train. Most of the road is covered by woods and trees, passes by the side of the beautiful Arlanzón reservoir and reaches the pretty town of Pineda de la Sierra. The Greenway continues to Monterrubio, but this section marked as a favorite is the one from Arlanzón to Pineda.
