Following the paved track from Bagà to Gisclareny, on reaching coll d'Escriga, we will leave the vehicle and head perpendicularly to the right to some meadows that must be crossed. Passing beside a pool, we will go into the forest heading NW, where we will soon find the depression of the avenc G-1; the avenc G-3, according to its explorers, is on a small rocky promontory in the middle of the forest, less than 200 metres from the avenc G-1, but we do not know in which direction from it.

Coordinates without much reliability, they only indicate the area where it could hypothetically be.
