Avenc del Querol

From the road closed to traffic that goes to the Campgràs doline, we must take the path that passes by the avenc de la Silvia, Asensio, Lluís Sola and Llambrics and that comes back out onto the road at the height of the Campgràs doline. On reaching the flat area where the avenc de la Sílvia is found, a small path heading south will lead us to the beginning of a ridge where we will find the avenc B-3; from here, to the left and heading east, we will see a collapse, and in its lowest part the cavity opens.
