Avenc del Mas de l'espluga

Located in the Serra de l'Obac. To get there from la Pola, take the path that leads to the balma de l'Espluga; once past the Quarto de Reixa, just before descending directly toward the turó de l'Espluga, leave the worn path and follow the ridge in a S direction until reaching the old mas de l'Espluga; once there, descend a little down the ridge toward the side of the torrent de l'Espluga, about 50 metres more or less, and continue in the opposite direction, as if retracing the path, but paying attention to the abandoned terraces that we will come across half covered by vegetation. The pit is located just as we cross a small torrent and begin to climb a gentle ridge. The dimensions of the entrance help to find it.
