Once past km 20 of the road from Isona to Coll de Nargó, we will follow the track on the left in the direction of l'Obaga Negra, and once past it we will again follow the left in the direction of coll de Llívia. From this col, we will follow a path on the left that runs along the ridge of the col to continue on a steep climb in the direction of l'obaga de Plan-de-riba and el Grau de Queralt. Halfway up the climb we find that the path divides; if we leave both paths and continue climbing through the middle of the forest in a SW direction we will reach the upper flats where the entrance of the cavity opens. Another option, though it is a longer detour, is to continue along the path on the left until reaching el Grau de Queralt, where a small trail passes in the direction of el Cap de Carreu and passes very close to the cavity.
