Cova Gran del Grau de l'ós

The cave is located in the barranc del Grau de l'Ós, in Riu de Cerdanya. From the Túnel del Cadí area, take a track that leads behind the toll booth. Here you must leave the car and continue on foot along the torrent; through a lower tunnel you pass to the other side of the road. Within a few metres you enter the barranc del Grau de l'Ós, which must be ascended. In the most gorge-like area, also known as Estret de Canals, is the Xemeneia lateral on the right wall. Continuing upstream along the barranc, some steps must be overcome until reaching a characteristic point, where an enormous fallen block has become wedged between the walls of the gorge. It must be overcome on one side where a space remains to ascend and with the help of an iron ladder installed for this purpose. Back in the torrent bed, you must continue climbing and after a few more metres ahead is the Cova Gran, half hidden by the vegetation.
