From la Riba along the TV-7044 road towards Farena, after km 3, a small parking area appears on the left below the youth camp. From this point, a path crosses the Brugent river, leaving the Moli de la Font Gran on the right; we leave a path towards la Riba on the right (signpost) and, following the main path, we come to another junction, which we follow to the right, passing by the avenc dels Tres Grans and del Xalau. Then we come to a new junction which we follow along the left-hand path towards the Penya Roja (signpost Penya Roja-Cingle dels Pins Alts). We find a rope on a small rise; a few metres past this, we turn right in a N direction for some 30 mts through the weeds, where the mouth of the pit appears beneath a large block.
