The most advisable approach is from la Morera de Montsant, going up through the grau de la Grallera until reaching the Serra Major; from there we will look for the path that leads to the Comellar de l'Os, we will continue along the ridge leaving on the right the path that descends to the Comellar, continuing until reaching the channels where we will find some cavities, following a very faint trail we will arrive at the pla de l'Escoter, in the very middle of which an important depression can be seen, following it all the way we will find quite a few entrances formed by boulder collapses, with no further story. On one edge of the depression, the entrance opens in the form of a fissure structured in a fallen rocky area. Approximate coordinates without much reliability.
