This cavity opens to the west of the roca Senyús, right in the middle of the Plan de Calama, which is a hanging basin at 1800 metres of altitude.

To reach it, take the track that from near Bóixols heads towards the Obaga Negra and the coll de Llívia; from there we will continue along the track in the direction of Hortoneda. Shortly after we will find a first track on the right that heads towards Cal Magí; we will continue along the one on the left and after a little more than 3 kilometres we will find another track on the right where the circulation of vehicles is prohibited. Following this track, after a few hundred metres we will reach a metal water basin where there is a spring and a watering trough; we will climb parallel to the torrent that comes to us from the left until we find some wire fences, which we will jump over to go into the Plan de Calama, where at the bottom we will see how the roca Senyús rises; continuing in the direction of it through the middle of the plain we will find the cavity.
