Graller d'Espills

The pit is located in the Serra de Lleràs, in Tremp. In the old records for this cavity, access was recommended from Talarn and Montibarri, due to the absence of tracks passable by vehicles from the Esplugafreda side. At present this path can still be used, but it is more advisable to go via Esplugafreda and follow the path that leads to the Botet de Casa Rei, climbing up the right-hand slope of the barranc dels Botets, a tributary of the barranc d'Esplugafreda; at the height of the barranc del Graller, the path changes slope and climbs up the left side of the ravine to a col where we will leave the vehicle. The enormous entrance can be seen from some distance. Care must be taken to spot a cairn on the left and, once past it, we find a sign and a track that branches off to the right (it is about 7 kilometres from Esplugafreda). At this point we leave the cars and go back to the cairn that marks the start of the descent; we zigzag a little and follow the cairns that in a little over two minutes leave us at the entrance of the pit.
