By the C-1413b road, from Hostalets de Balenyà to Centelles, shortly before kilometre 18, we will turn right towards Fontderola and el Puigsagordi. Once at the Pla de Castellar, we will head N, towards the antennas located at el Castellar. From the SE part of the buildings, a path sets off skirting the cliff in a S direction; we will follow it for about 500 metres until reaching the coordinates (ED50- X:433517; Y:4629755). At this point a trail begins that descends through a pass allowing the cliff to be overcome, and where on the right are the coves PG-3 and PG-4. We will continue along the base of the cliff in a N direction, for 60 metres, where we will find the cova PG-8 4 metres above the path and the cova PG-9, 5 metres further N.

Very approximate coordinates.
