It is a canyon with a constant water flow, though reduced during the summer months. Despite the long and steep approach (about 1 hour 30 minutes), this is a nice, wild, alpine Canyon. The most interesting section starts at around 1200 m elevation and continues down to the valley floor; above that, there are other rappels of limited interest.

Park in the village of Fervento (VC) in Val Sermenza (it's not easy to find a parking).

Walk along the provincial road toward Rimasco, pass the hydroelectric plant on the Sermenza river, and after a few minutes, take the iron bridge on the left to cross the river. From there, follow trail 381 toward Alpe Chignolo. After about 1 hour of hiking, cross a small iron bridge reinforced with supports over a minor stream, then continue the final 3 minutes uphill in the forest along the CAI trail. Here starts the little path to the alternative Start (see later description). Normal Start: Walk further to the next waycross at 1330müM, take the right way until you reach the canyon. This start is 50m higher and 270m longer than the alternative start. Path to the alternative Start (slippery, exposed, 40m abseil from a tree into the canyon): At a junction, trail 381 continues left toward Alpe Chignolo; for the canyon, keep right (sign Canyoning) following stone cairns. Continue contouring just below trail 381 without losing elevation for about 5 minutes through the forest, until you must climb slightly — keep right here (a short exposed section). From there, traverse gently left and start descending toward the stream through rough, steep terrain (about 40 m elevation loss).

A alpine canyon featuring 12 rappels, the highest being 50 m, with several linked rappels, handlines, and a couple of deviations. It is well equipped, mostly with chain anchors and rappel rings on the more complex pitches. The section leading to the 50 m rappel is the highlight — aesthetically striking and engaging. After the final 27 m rappel (with a high left-hand deviation and a difficult rope retrieval), continue along the streambed among boulders and slippery sections that should not be underestimated, until reaching a small bridge. Exit to the right here and walk about 5 minutes to return to the starting point. Warnings: > Rope friction inside the small grotto at the end of the third rappel (C32). > Rope retrieval issues on the fifth rappel (C28) due to vegetation that can snag the rope. > Friction at the very start of the sixth rappel (C30). > Jump immediately after the C50: shallow water, not recommended.

The canyon carries a consistent water flow all year round.
