Avenc de la Tica

At the Soleia del Sabater Vell. From the road from Castellar del Vallès to Sant Llorenç Savall, a few metres after km. 12 there is the pont del Sot de la Carda, where the track that leads to the turó del Muronell begins. Follow along the right bank of the torrent, cross it once and, when it is crossed a second time, on our right a path leaves that climbs up to a track; we will follow it up until we pass another torrent; before crossing it, on our left a path can be seen among the brambles that climbs along the side of the torrent, a few metres from the path and under some holm oaks is the pit.
