Avenc de la Montse

Going along the N-340 road from Vallirana towards Vilafranca del Penedès, once past the coll d'Ordal we will find two ponts on the road; just when the second pont ends, on the left there is a small esplanade from which two tracks start. We must take the leftmost one, which descends towards the torrent; we will follow it for about a hundred metres and climb to the right about 5 metres up to some abandoned “sparry calcite” quarries. The pit is inside the quarry.
