Short but nice and narrow stream.

Short but nice and narrow stream.

From the A26 highway, take the exit for Villadossola and follow signs for Valle Antrona. Drive up the valley past the hamlet of Rivera. Cross a bridge over the Ovesca stream and, after about 500 m, park on the left near a festival/recreational area.

Behind the chapel in the festival area, hike up through the woods following a trail (which becomes clearer further up) until reaching the intake tunnel and the streambed.

No particular difficulty. Some unequipped rappels (abseils) to be downclimbed or descended using natural anchors.

Exit directly at the car.

Almost non-existent flow rate due to a water intake at the start. To be done as a fallback option when other streams are impassable.
