An awe-inspiring descent, a deep and unsettling canyon, in our experience, one of the most beautiful.


Difficulty: Expert
Duration of the canyon: 3-4 h
Total Duration 4-5 h
Shuttle: 10 min

Approach Hike: 15 min
Return hike : 5 min
Highest Abseil: 35 m

Recommended age: from 16 yrs
Period : July – September

Recommended only for participants who already have some previous abseiling experience.


From the meeting point, we will drive to the lower parking site where we will leave at least one vehicle with towels and dry clothes. With another vehicle, we will drive to the upper parking site in the hamlet of Altoggio, a small, picturesque town where time seems to have come to a standstill. From here, 15 minutes along a path will take us to the canyon entry point. After the briefing on safety and descent techniques, off we go into the water. The canyon is spectacular, deep, with crystal clear water. A few jumps and breathtaking abseils. An experience that anyone who loves canyoning simply cannot afford to miss out on.

This experience is aimed at participants who have previous abseiling experience.
