Karst area and rugged terrain. Few indications of the path to the top. Some milestone of stones and scattered orange signs. It is essential to carry a GPS to navigate.

Beautiful path through the Oak Grove of the Remendón Forest, mostly a dirt path, but there are also areas of stones, streams that cross or go down the path... and all next to the old Mongarrido canal and practically in its entirety in the shade, so it is ideal to do it in summer when the sun shines.
