Avenc de Can Rial

If we start from the village of Navès, we will follow the road towards Solsona for about 3 km, at which point an asphalted track comes out on the right (signposted as “camí de Busa”). After a few kilometres we will reach the coll d'Arques and we will continue along the track for close to a kilometre more to leave the car at a bend to the left from where we will already see the summit of the serrat de la Guàrdia. A few metres further on, a path comes out on the left, an old abandoned track, which we will follow for a little more than 5 minutes to leave it when we take a faintly marked trail that comes out on the right-hand side. The trail heads for the grau de la Guàrdia (or de l'Areny, according to maps) which climbs over the cliff located on the western slope of the serrat de la Guàrdia. On one of the bends of the grau we will find the entrance of the cavity right beside the path. There is a flimsy fence to prevent people from falling in.
