Park at Puerto de Piqueras, a mountain pass on the N-111A. There is plenty of space.
(S/E) Set off along a grassy path between some trees, heading north-west.
(1) You’ll soon come to a more clearly marked path; follow it to the left. Continue for a few hundred metres until you reach a larger, flat grassy area, then cross the fence. Follow this fence to the summit. The path occasionally passes through very low, fairly dense vegetation. The highest point is marked by a clearly visible, cemented geodetic marker.
(2) Take the same path as on the way up, but in the opposite direction, to return to the starting pass (S/E).
