Although it has always been cited at Toloriu, now grouped into the municipality of el Pont de Bar, in reality, and by very few metres, the entrance is located within the municipal area of Cava, although we had mistakenly placed it in that of Arsèguel.

You must leave Toloriu by the paved road and before reaching the junction (Quer-Bar) turn right onto a wide forest track; you can follow the signs of the BTT circuit. You will soon reach the small font del Bon Arbre, then you will find a junction where you continue to the left; soon you will be in the woods, then there is another junction, this time you continue to the right, until you reach a beautiful meadow where the path makes a double S, with a new junction that you follow to the right, climbing, you reach a hairpin bend where on the right a small path branches off along which the BTT route goes; therefore from then on you will no longer find any other bicycle signs.

Continue along the main path and pass a hairpin bend in the middle of the torrent; further on you will find another hairpin bend, where you continue to the left, which is the more worn path; continue through the woods now on a fairly long straight to reach the Collet de Moscalló, where a large meadow begins on the left side of our path.

From here, a path branches off to the right, barely visible at the beginning, which gradually gains slope, passes beside the ruins of the Era del Fuster and in a couple of bends you reach a flat area within the woods where the path fades until you reach the slope of the torrent d'Arsèguel; now we are at about 1520 in altitude; up to here from Toloriu it can take about 90 minutes over a distance of 4.8 kilometres.

Sometimes we find cairns that lead us to the hidden entrance of the cave facing west; a small trail will leave us above the entrance.
