Avenc dels Pelagons

Going along the BV-2111 road from Sant Pere de Ribes to Olivella, on reaching kilometre 13.8, just after crossing the bridge over the riera dels Pelagons, on the left-hand side of the road a track begins that is closed to vehicle traffic; it must be followed for 2.36 kilometres and along the route we will cross the riera dels Pelagons up to six times. Almost reaching the end of the route we will leave the masia dels Pelagons de Baix (in ruins) on the right. Once past it we still cross the riera twice more; after crossing the last one, 43 metres along and on the right-hand side of the track (ETRS89 398474 – 4575669) a path marked with cairns starts that in about fifty metres leads us to the cavity; this is located 20 metres above the track.
