The GR 8.1 to Pitarque leaves by the old road from the road crossing. Cut the track from the Monte Santo tower and go up the old pass to this farmhouse. Past the tower, it takes an alley between walls and comes out briefly onto a road before continuing along a path that crosses the Cerrallosa hill. Descend to a watercourse and take advantage of a stretch of trail that allows you to ascend to the pass on the adjacent hill. From here, the path begins a frank descent, along the terraced margin of a wide lateral watercourse, until it ends at a farmhouse on the side of a track that leads to cross the Pitarque River and then climb up to the town.
