Equipped rather quickly; it’s necessary to add missing anchors for handlines and some rappels. The water is icy all year round due to the altitude, exposure, and the high peaks from which the Vogna stream originates. Even in mid-summer, it’s possible to find a snow patch inside the canyon.

From Riva Valdobbia, drive up the Val Vogna road until you reach Ca’ di Janzo; park there.

Continue along the road, first paved and then unpaved, until you reach Peccia. From here, take trail 201, then at the Napoleonic Bridge, switch to trail 205 toward Passo del Maccagno (GTA route). Follow this trail to Alpe Buzzo Inferiore. A little further ahead, you’ll pass above the canyon to be descended (the narrow corridor is clearly visible). Continue for a few dozen meters and enter the stream as soon as possible.

The descent begins with some easy downclimbing until a marked left turn (where a large avalanche often deposits). Here you’ll find the first rappel, C5 (not equipped), immediately followed by C7 left (single anchor) — below this point, the canyon becomes very narrow. Two beautiful pools lead to C12 right (single anchor, possible jump into a magnificent pool below), followed by C7 (not equipped, precise jump possible) and C3 (not equipped, snow may persist here). You then reach the tallest waterfall, C25 left (single anchor; the approach is exposed — a handline would be useful). The pool below is spectacular and allows for several high jumps. Next comes C18 right, marking the end of the canyon. From here, walk about 10 minutes to reach an easy exit point on the right that leads back to the trail.
