In the Montsec de Rúbies (Camarasa). Going up the canal de Migjorn, which is located immediately to the E of the Portella Blanca, and at the height of the cingle del Montsec, this is split in two by a projection of the cingle. Going up the right-hand canal and on its W wall, right at the start, is found cave A, a small rock shelter of no interest; opposite it and higher up, at the foot of the old path, today covered by vegetation, is located cave B; further up and also at the foot of the path, is found the mouth of cave C, opposite which and hanging on the W wall of the canal can be seen the mouth of the so-called cave D, which is nothing other than a hole that crosses the rock projection, also opening onto the E wall of the left-hand canal.
