Avenc de l'Ivan

It can be reached from the old Coll d'Ordal road via the track heading to the quarry, now converted into a landfill; after 300 metres we turn right and follow the main track for 1.67Qm where we will find a junction, we continue left for 170 metres until reaching the electricity pylon where we will park. The cavity is on the right of the track heading E, 73 metres in a straight line from the electricity pylon, but with no path, it is all covered in undergrowth. The cavity is right next to a young pine tree that has a metal danger sign hanging on it.

It can also be reached from Corbera de Llobregat following the BV-2425 road towards Gelida; just after kilometre 2 we turn left until reaching a roundabout, we continue left along Carrer Cabernet to the end where the track continues towards the Puig d'Agulles passing through the Coll del Portell; right at the start of the climb to the Puig d'Agulles, we turn right onto the track heading to the Coll d'Ordal, we follow it ignoring any turn-off for 730 metres, ending up at the junction which, continuing right, after 170 metres will bring us to the electricity pylon where we will leave the vehicle.

It should be borne in mind that for either of the two approaches it is advisable to have a high vehicle; a 4x4 is not necessary.
