Valdevacas de Montejo is a moorland town, it has a mountain atmosphere, it is between hills and valleys populated by junipers and holm oaks far from the Riaza River but it has always been linked to the river and the natural wonders of the beautiful limestone canyon. And also with its secrets, myths and hiding places. In the square there is a panel of local trails and another of the routes of the La Serrezuela MTB Center. And there is also the source. The trail leaves the square along Calle Mayor to a crossroads on the outskirts where the posts of PR-SG 7 Senda de la Ermita del Casuar appear, one of the hiking itineraries of the natural park. The route continues to the left and soon a detour appears to the right. You can also take a shortcut directly from the square without passing through the beginning of the trail. At the crossroads there is a small enclosed area with a restored traditional still. The road leads away from the urban complex along an agricultural lane between crop fields. The beginning is very comfortable down some rural slopes, to a meadow of orchards in the Pozos stream and the landscape changes completely. The track climbs through a mountain of juniper trees to the Los Picachos moorland and begins the descent towards the gorges of the Riaza River. The road is well signposted with the PR-SG 7 milestones on the detours.
