Expert level, Difficult

Recommended period: MARCH-OCTOBER

The WALSERFALL Via Ferrata runs along the rocky wall that skirts the Agàro waterfall, downstream of the lake by the same name. It reaches Piodacalva, where a handful of barns and huts stand on a wide and panoramic rocky terrace. This is the Walser region, and as a tribute to these ancient and wise mountain people, the via Ferrata has been named WALSERFALL, combining the terms “Walser” and “Wasserfall” (waterfall).

The access trail (code H00 up to Osso) starts behind the old dairy farm and is marked by specific signs. From the road bridge in Osso, follow a small trail along the river until reaching the Via Ferrata base.

From Piodacalva, the Via Ferrata’s arrival point, head back to Croveo in about 50 minutes following the H06 trail. Alternatively, from Mollio a trail descends to Ecchio and then to the village. These trails have some exposed, unprotected sections that require attention.

Wonderful views along the beautiful waterfall of the Rio di Agaro are awaiting you.

The most difficult sections are on the wall known as “dei tetti”. This wall has a long and aerial traverse. On the final wall that leads to Piodacalva there is a very exposed overhanging passage that requires significant fitness and expertise.


The Via Ferrata is a mostly artificial route that leads the mountaineer on steep walls provided with safety steel ropes and steps anchored to the rock.

It is fundamental to be experienced climbers, physically fit, and technically well trained with full awareness of how to handle void and climbing.  Those who have never approached the Vie Ferrate’s climbs are recommended to hire a professional UIAGM Alpine Guide.

It is mandatory to be equipped with specific personal protection equipment suitable for the activity and to be familiar with its correct use:

  • Climbing helmet
  • Climbing harness fully latched and well-tight in the flanks and thighs plus self-belaying set with energy absorbers
  • gloves
  • rock climbing shoes
  • A double safety longe already fastened to the harness is recommended

Keep in mind that the shocks caused by a fall from the Via Ferrata are extreme. No material can withstand such shocks, and thus the use of energy absorbers is mandatory
