Avenc del Mig

The easiest access is by ascending the Fondo de Vallbona from the Rat Penat urbanisation. This begins at the roundabout of the urbanisation (plaça de l'Alcalde Güell, where we will follow the street located furthest to the right, arriving practically at the bed of the Fondo de Vallbona. In this sector it is wide and stony and can be crossed through the middle; in some stretches we find a very faint path that passes a few metres above the fondo. Further on we find the confluence with a stream that comes down from the cucona la Sibina, and past this one must look for a path that ascends along the hydrographic left and some 20 metres above the fondo and that presents some retaining walls in the middle of its route. This path leads again to the bed of the stream, near the confluence of another stream that collects all the tributaries of the area of the Bassot de l'Arbre. From here one must follow a little more than a hundred metres along the main torrent, much narrower and choked with undergrowth, until reaching the confluence of two gullies that come down from the Campgràs. From the point where both join, one must ascend in a straight line some 10 metres and the entrance of the avenc Vell is found, and a little to the right the avenc dels Bessons, and still between the two we find the avenc del mig. This itinerary is done in approximately 1 hour.
