In a high mountain environment, this stream has carved beautiful formations in solid rock.

The best place to park is at the parking lot near the stream (46°05'38.6"N 10°25'48.4"E), just before Fabrezza coming from Saviore. Alternatively, it is possible to park where the access road to Alpe Maè begins (46°05'27.1"N 10°25'17"E), or use a shuttle between the two parking spots (1 km).

From the parking lot near the stream, go back along the paved road for about 1 km. Just before crossing the Valle di Os, a dirt road branches off to the right leading to Alpe Maè. At the alpe, keep to the right and enter the forest, ascending straight on trail traces until reaching a grassy area and then a flat trail. Follow the trail to the right, crossing several small valleys. At a fork near a charcoal kiln, take the lower trace, which will soon lead to the pine forest felled by Storm Vaia in 2018. Armed with a saw and patience, find a way through the maze of logs, continuing on flat ground until reaching the stream. Once in the streambed, follow the stream until the first rappel, equipped with a ring on the right (46°05'49.6"N 10°25'49.1"E). About 1 h 30 min for 300 m ascent.

From the last vertical drops, the road and parking lot are already visible; it is enough to descend a couple of artificial steps to reach them (1 minute).

Flow assessment: from the parking lot, the last three rappels are very clearly visible.
