On the left hydrographic slope of the riera d'Escales, raised about 50 m of drop above the streambed. About 160 m in a straight line to the WSW of the coll de la Veta.

Starting from Sadernes we will follow about 2 km along the track that goes up the riera de Sant Aniol until reaching a place set up for vehicle parking (Parking-3). Right here a path starts that crosses the riera to go up the other side until reaching the coll Roig, where we begin the descent along the other slope until reaching the streambed of the riera d'Escales. Now we must go upstream. Soon we will see on our right the cova de Coll Roig. We have ahead a long walk along the streambed of the riera, full of gravels, pebbles and large blocks that must be overcome. Thus we will reach a marked bend that the riera makes to the right. This bend is the southernmost point of the riera. About a hundred metres past the bend, the camí de la Veta, a narrow path, comes out on the right (hydrographic left). We will follow it, and when it begins to zigzag to go up to the coll de la Veta we will have to leave it towards the end of the second zigzag. We will leave it on the left to take a little-evident path that shortly brings us to a cliff that we will have to descend by a passage that allows doing so without difficulty. Then we must go downhill following the foot of the cliff. When the cliff turns left, we will follow it about 30 m more and we will reach the cavity.
