From the C17 road towards Puigcerdà we will enter the village of Sant Quirze de Besora at the traffic-light junction. We must cross over the bridge over the river Ter and at the end of the bridge, turn left onto the BV5227 road. We will cross the railway line and continue for about 7 kms., until we reach Santa Maria de Besora. Almost at the end of the straight stretch that crosses the village, we will find on the left the signposting indicating "to Ripoll via Llaés". We must take this narrow cemented track, which is in good enough condition to be driven with a car. You must be alert as the bends are very tight and we constantly find steep ups and downs. After travelling 3.5 kms. we will reach the coll de Beví; before reaching the coll we will find a track on the left, which we must follow, leaving on the left the turnings for the Beví Gros and further on that for the Beví Xic; further on the track turns towards the N, and on this stretch we will find markers that will lead us to the entrance of the great fissure where the bufadors are located.

The two entrances of the cavity are located at the upper part and to the right of the great fissure, between the TIM pit and the dels Tigres pit. Entrance no. 2 is closer to the former and entrance no. 1 to the latter.
