Difficulty: easy, even there are a few sections of the path, that are very narrow and pass parallel to the precipice without guardrails.
Time: 1 hour only one way
How to get there: we take the A 138 national road in the direction of Barbastro. After 18 km you arrive in Mesón de Ligüerre, where you have to take the detour to the left towards La Fueva. After 3 km you cross the bridge over the reservoir of El Grado. Behind the bridge there is a small parking zone, where you can leave the car. There are signs that mark the route (Gorge of the Entremon). This route is part of the GR-1. There are also posters on the ornithological wealth of the route along the way.
