Avenc del Solà de la Mariana

Leaving Tortellà in the direction of Montagut, we soon find on the right the turn-off towards Sales de Llierca. From the aforementioned turn-off we will follow the road in the direction of the farmhouses of Monteià and Orri; the road ends up becoming a track. 325 metres before reaching the turn-off that leads to the Masia de l'Orri we will find on the left of the track the font de la Borada (as it appears on the sign at the spring). About 80 metres before reaching the spring, from the left of the track a branch track leaves in the opposite direction to the one we were following and which we will follow until it ends. From this point we will access the clot de la Mariana, which we will go up for about 50 metres, where we will find the entrance of the pit about 4 metres above the thalweg, and on the right of the torrent.
