Park at the side of the road just past the Puente del Entremon on the right when coming from the A-138 (Meson de Liguerre).
(S/E) Walk up the road for a few metres, then cross to the left to find a path that climbs towards the gorge to the north. Follow this steep path, which has a few sections requiring you to use your hands or a handrail. As you approach the cliffs, the path, which follows the course of the Cinca upstream, veers to the right.
(1) Here is a tricky section. The path is carved into the cliff face. It is narrow and vertiginous, but you can get through without difficulty by keeping well to the right and holding onto the handrail. Shortly afterwards, a short section fitted with rungs may require you to use your hands. The path then continues gently through the woodland. Towards the end, a somewhat steep climb with worn steps leads to a wide track.
(2) Follow it straight on, then take the road on the right which passes through a tunnel (a head torch isn’t essential; there’s a rather temperamental motion sensor, but in any case this section isn’t long). At the tunnel exit, continue along this road, pass through a second tunnel and descend via a flight of steps to reach the crest of the dam. A lovely view over Lake Mediano and the iconic bell tower of the village of the same name.
(3) Retrace your steps along the same route as on the way out to return to the car park (S/E).
