Going along the road from Alcover to Capafonts (TV 7041), before reaching Mont-ral and a few metres before reaching Km. 10, an initially asphalted track comes off, crossing the Pla de les Perdius. We will always continue straight ahead, ignoring the forks, until the track ends in a widening of it in the middle of the forest, on the ridge of the serra d'en Clarà. From this point and in a N direction a path comes off that leads us to the avenc del Cabirol. From here we must continue in a direction O25N along a path opened through the dense forest for a little more than a hundred metres, where we will find the entrances of the pits NR-6, NR5 and NR-4. From the latter we will follow the path in a direction N33Oest for 90 metres, where we will reach the upper part of a cliff of about 10 metres of drop; right in front we have a rock wall that makes the space occupied by the cliff look like a channel; at its base opens the avenc de l'Escletxa; we must descend by rappel to the entrance of the avenc de l'Escletxa; from here begins a ramp that descends the channel; at the end of it we find the avenc de la Dolina.
