Caratteristiche

Località

From the barri de l'Hospital in Olesa de Bonesvalls you must go to the municipal sewage treatment plant; the track continues along the side of the riera de Begues and very often crosses it. After a little more than 2 kilometres, the riera makes a turn of almost 360º, forming a narrow section of the surrounding massif (coll Estret). On the S slope of this coll, some 20 metres above the riera, is the small entrance of the pit.
