From Castellterçol we will follow the BV-1245 road towards Granera; after kilometre 2 we will turn left onto the paved track towards Coll d'Ases and Gallifa. After about 7 kilometres we will reach Coll d'Ases; on the right-hand side and right next to the traffic signs a path starts, which we will follow until we find an iron pole where the path splits; we will keep left, which will take us to the base of the cliff where we will find some cairns. We will soon find the first of the caves a little more than 250 metres from Coll d'Ases; a few metres further on we will find the rock shelter and, just past the rock shelter, there is the first of the entrances of cave no. 2, with a fig tree at the entrance.
