We will leave the village of Vallfogona de Ripollès, heading towards the castle of Milany along a track that starts beside the cemetery. When we reach the first junction we will take the path on the right that leads to the font de la Tosca, we will pass right by it and continue until the track crosses the torrent del Tornall. Here we will leave the car to take a path that follows the stream upstream on the hydrographic left, we will cross a small bridge and continue along the torrent bed, we will pass beside small cascades that form a very bucolic landscape, until we find the Llastanosa waterfall, a very well signposted waterfall with important deposits of limestone tufa; right below we will find the rock shelters.
