By the L-401 road (from Coll de Nargó to Sant Llorenç de Morunys), once past the small village of Cambrils and about 200 metres after km. 21, a group of farmhouses (Cal Roca, Ca l'Espunyes and Cal Sala) is found on the right.

Level with them and on the left of the road a track begins. At the first left-hand bend a path must be followed that comes in flat and reaches the Cal Sala spring. Above it there is a conduit that acts as an overflow in times of heavy rain. Following the crag upwards and to the left of the spring, a small fissure is found that works as a trop-plein of the spring. A little higher up is the upper cave of Cal Sala.
