The excursions include the descent of narrow gorges deeply carved into the rock not far from Bagni di Lucca and the Garfagnana. The gorges, hidden and uncontaminated, are crossed by small streams with a steep slope and the participants proceed on foot with a pack, climbing harness, rope and protective helmet. These paths will put you in front of some obstacles such as waterfalls, rock climbs, slides, flooded corridors, small lakes.
