Cova del Sust

We will leave the vehicle at the hostal del Bac and walk to the house of la Coromina; following the same path we will go up to the next farmhouse, Can Biel, at the first very sharp bend, where there is a pole of the power line, we will turn off to the left (W-NW), and follow the path until we reach a point from which we can see on the other side of the valley the roof of the Molí de la Coromina. Then we will have to leave the path and climb without a trail through the middle of the mountain, heading for the cliffs that remain on our right (E). Following the cliffs along their base we will find the cova del Sust.
