Balma de Sant Martí dels Castells

The rock shelter is visible from the Puigcerdà to la Seu d'Urgell road, just as you pass Sant Martí dels Castells, on a stretch of the old road before the tunnel.

Following the abandoned stretch of road, when it turns 90º to the left we climb up a very steep torrent for about 30m and on reaching some rocky spurs, we will skirt along the right until we reach some marly and reddish limestones where we will find the cavity.
