Taking the road from Alcover to Capafonts (TV 7041), before reaching Mont-ral and a few metres before reaching Km. 10, a track emerges, asphalted at first, which crosses 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 emerges that leads us to the avenc del Cabirol. From here it is necessary to 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 seem like a channel, at the base of this the avenc de l'Escletxa opens, it is necessary to descend by rappel to the entrance of the avenc de l'Escletxa, from here a ramp begins that descends the channel, at the end of this we find the avenc de la Dolina. We pass over this and head towards the E through a kind of valley, at 35 metres of distance and on the left at the foot of a wall we will find the two entrances of the avenc de la Sala, we will continue towards the E and 35 metres further on we will find in the very middle of this valley the entrance of the avenc de la Formació, we will continue ascending this valley in a direction E13S for 175 metres, arriving at the point where the rocky wall begins to close it, then one must go towards the left, the avenc dels Blocs (M-8) is located 14 metres to the N of the avenc de la Sílvia (M-7).
