Avenc de Sant Martí

At a bend in the L-511 road (Coll de Nargó to Isona) and at km 31, a track begins that leads to the hermitage of Sant Martí de la Plana. Here the vehicle must be left and the route continued on foot, descending a few metres to the south-east where we will find traces of an old path, (in June 2024 it was still marked with old faded plastics tied to the branches of some trees and with some fairly old yellow paint marks) we first follow along the sunny slope below the 1003m contour and shortly afterwards we climb to a small col and pass into the shady area of the Bosc de Sallent heading predominantly E until gradually gaining the nearby ridge. One must always continue towards the E until reaching a point (X: 356090; Y: 4668890) located between the start of two gullies that descend towards the Sallent river. On reaching this point we leave the path and must continue towards the N, descending between the divide of the two torrents until finding the pit.
