From Cornudella de Montsant we will take the Cova Santa path (GR-174), which we will leave at the turn-off towards Sant Joan del Codolar and continue up to the Grau del Montsant. We will continue onwards and shortly before the right-hand bend that the path makes before reaching the Grau del Tomaset, we will look to our left on a steep slope of the terrain and between two conglomerate cliffs we will see the collapse where the cavity is located.
