The Soana Valley include a heart of rock which is the Forzo valley. Climbing developed on these difficult and imposing granite walls starting in the 80s, after the group of "Nuovo Mattino" led by Motti, exhausted the exploration on the Corporal and the Sergent walls. We propose a classic route on the Alpherian wall called "Allegro con Brio", a route of about 220 m with 10 pitches, graded 6a / 5c obbl; beautiful climbing in crack and bolted plate, to be integrated with some friends. Athletic and very aesthetic climbing that follows the cracks in the wall of the Alpherian. A route of pure enjoyment and satisfaction.
