On the TV-7044 road going from La Riba to el Pinetell, at the height of the Molí de la Font Gran and just below the Campament Juvenil, we find a designated parking area. On the right-hand side of the road there is a path that descends to the Brugent river, at this point almost always dry; you must cross it and follow the path towards the cliff. Soon we will find a junction: the one on the right leads to the cova Cartanyà and to the Penya Roja, you must follow the one on the left. Shortly after we will find a new junction, we will follow the one on the right. The path runs along the base of the Cingle dels Pins Alts where there are more than sixty climbing routes. After passing a fairly steep section the path becomes flat and descends a little; at this point the mouth of the cave is found. Just above the cave there is a metal plaque with the name of the route Ploms, although this is not visible until you have passed the cave and the path climbs again.
