Forat Nº1 de la Llau Fonda

Three and a half kilometres after passing Sapeira in the direction of Espluga de Serra, and one kilometre six hundred metres before reaching the village of Castellet, the track is crossed by a very wide torrent that comes down from the serra de Lleràs. Going up this torrent about 100 metres, we find on the left a building like a shed; continue on until reaching a fork of ravines (the right-hand one goes towards the graller de Castellet or Espluga de la Fageda). Take the left-hand one until reaching the confluence of three torrents; here you must follow the right-hand one (Barranc de la Pedregor) and continue upstream to a long gorge section in which 4 or 5 cascades must be climbed. Further on the bed widens and on the right (left slope) there is a scree slope which, once climbed, leads to the large lower opening of the pit, visible from the bed of the ravine. Coordinates of very low reliability.
