Access to the place
Hiking to the start 5'
Descend to the level of the last houses of Cantina Ferraris and cross the riu (it is hidden by vegetation but close by). You'll soon come across an old, broken bridge and, opposite, cairns and the trekking trail.
Follow the cairns on the path leading into the valley on the left. After about 15′, we leave a path that climbs to the left. Instead, always follow the bed of the riu Orrida, sometimes passing in the bed, sometimes to the right or left. In all, there are 3 cascades to be climbed, each one bigger than the last.
Cascade 1 is easy to climb with a rope, while cascade 2 is a climb, but it's in the IV+ category, so will be difficult if there's water. This cascade can be bypassed by the top left. Cascade 3 is 45m vertical and is the famous Cascata Piscina Irgas, unfortunately dry when we passed through. You have to go around it to the right on a steep path and exit onto the ridge to admire the canyon from above. End of the canyon.
Continue up the ridge to find a path marked with blue dots. Following it eastwards, you can again enjoy a bird's-eye view of the entire route before descending into the next valley, through the woods and then along the Riu Cannissoni to the parking lot.
