Fabulous track. We are in the “Biello Sobrarbe”; a historic area south of Ainsa is noted for his insubordination to Muslim control.
Visit Morcat it’s a must to enjoy a beautiful view and eat your sandwich there. It is inhabited town, but only by people.
This route is technical in general. You’ll enjoy if you control in trialeras (50% path).
Take a lot of water with you. Only source in the beginning of a path in Morcat.

Variant “Las Pozas of San Martín”: being in good shape do this track by descending the ravine of Sieste in area of natural pools carved in the limestone.
