This is a strenuous tour (500 vertical meters elevation gain on the approach), but it will thrill you right from the start, with a series of abseils (max. 50m) dropping you right into the middle of the deepest part of the canyon. This is followed by sections of real splendour, together with varied terrain passages and impressive fissures. An airy 42m abseil takes you into the cavern-like final stretch, probably the most spectacular section of canyon in all of Ticino. Several interesting, technical jumps take you through to the end. The approach time is approximately 75 minutes, actual time in-canyon is about 4-5 hours.
