WARNING! Artificial dam over the canyon.

Access: from Biasca head South and go beyond the village of Osogna. 700 meters before the railway station of Osogna-Cresciano (50 m before a Honda garage) take the underpass on the left, then turn right and follow the road flanking the railway, heading South, for 250 meters more. Parking is on the left, just before a building.

Approach: follow the steep path leaving from the bottom right corner of the parking, going into the wood; go beyond a bunker and reach the river bed. From here walk for about one hundred meters along the bed, walking under the beautiful triple fall with a little lake at its bottom, and then take the path going on the right bank, fording again the water just before the top of the fall. Just after the ford there is a junction: turn right and reach a little house in the half of a grass. Then follow a track leaving from the right of the building, overhanged by a big rock, rising until it joins a wider path which has to be followed walking towards the water, until you reach for the third and last time the bed.
