Attention, "relative" cyclability. Yes or yes you will have to push the bike in many sections, but the landscape is worth it. Framed by huge walls, in which griffon vultures nest, the place is of singular beauty, due to the capricious shapes that form the rocks. It has areas where depending on the season there may be problems because brambles and / or thorns have eaten the road.
