The gorge has no exit routes; once entered, you must reach the end. However, along the way, there are many points where you can take shelter in case of a flood. In summer, the water flow is low.

From S.P. della Valsesia, upon reaching Campertogno, on the left there is an uphill paved road leading to the hamlet of Orià. At the end of the road, leave the car.

From here, follow the old trail 286/86 to Colma di Campertogno, which becomes more evident in the forest after the small church of San Pantaleone. After a gentle start, the trail steepens to overcome a rocky section, then enters the Basaleto valley. Upon reaching the small tributary "Croso dell’Eva" (before the trail becomes steep again in a beech forest), descend along the Croso or through the forest for about 50 m until you reach the canyon. Total: 30 min.

Start by walking in a fairly wide streambed. After 10 minutes, you encounter the first MC10 right + C12 right, then a C20 right from a tree, leading to the large sloping waterfall. The large waterfall is divided into C30 left, which overcomes some drops, and the beautiful C40 left, ending in a very deep pool. Then C13 right, C17 left + C12 right.

Before the last non-equipped waterfall, exit to the right and ascend a few meters to reach the trail; 5 min back to the car.
