Via Ferrata Barrage de Moiry
The Via Ferrata Barrage de Moiry is one of the most scenic alpine routes in Valais, positioned directly above the turquoise reservoir of the Moiry Dam near Grimentz. Known for its dramatic atmosphere and exposed passages, this route offers a rewarding mix of challenge, height, and outstanding glacier views. It is a modern, well-equipped via ferrata built for adventure seekers who want an immersive vertical experience in a truly iconic alpine setting.
Trail Overview
Duration:
Approximately 2 to 3 hours for the via ferrata itself, depending on experience and pace. Additional time may be needed for approach and return.
Difficulty:
Grade: K3 to K4 (moderate to difficult).
The route includes steep vertical sections, traverses above significant exposure, and short but demanding overhanging moves.
Best for:
Intermediate and advanced via ferrata climbers with good physical condition, comfort with exposure, and solid upper-body endurance.
Exposure:
High. Multiple sections run directly above the reservoir on steep rock faces and airy traverses. Those sensitive to heights may find the route intimidating.
Required Gear:
Certified via ferrata set (Y-lanyard with energy absorber), climbing helmet, harness, gloves, and sturdy mountain shoes. A light windproof layer is recommended due to the altitude and dam winds.
Route Description
The route begins near the foot of the Moiry Dam, with a short approach leading to the first anchored cables. The initial section consists of solid vertical steps that help climbers gain elevation quickly, providing immediate exposure above the deep-blue waters below. The line then traverses horizontally across slabs and walls, offering a mix of natural holds and metal rungs.
As the climb progresses, the terrain becomes steeper and more technical. Several sections require careful foot placement and controlled movement while clipping along the cable. Short overhanging passages test upper-body strength but are well protected. The final part features an airy crossing before ascending toward the exit point, where the view opens dramatically toward the Moiry Glacier and surrounding peaks. A short descent path leads back toward the dam.
Highlights
Striking aerial views over the Moiry reservoir and its vivid turquoise color.
Close proximity to the high alpine scenery of the Moiry Glacier.
A well-built, modern route with safe, high-quality equipment.
Varied movement, including vertical walls, traverses, and short overhangs.
Photogenic setting with unique contrasts between rock, ice, and water.
Difficulty and Required Skills
This via ferrata is best suited for climbers with prior experience. The moderate-to-difficult K3–K4 grade demands:
Good upper-body strength for overhanging steps.
Comfort moving on steep, exposed rock faces.
Efficient clipping technique and awareness of rope management.
Stable footwork on rock and metal rungs.
Basic alpine safety knowledge, especially in changing mountain weather.
Beginners may find the exposure challenging, and it is not recommended for those unfamiliar with via ferrata equipment.
When to Go
The ideal season spans June to October, depending on snow conditions. Early summer may involve remaining snow patches on the approach, while late autumn can bring icy sections and cold winds. Mid-season offers the most stable conditions and the most vibrant color in the reservoir below.
Access and Logistics
The starting point is the Moiry Dam, located above Grimentz in the Val d’Anniviers, Valais. From the dam’s parking area, follow the marked trail toward the base of the via ferrata. The approach is short and well-signposted.
The route exits higher on the slope, and a clear descent trail leads back to the dam. Weather can change rapidly at altitude, so monitoring conditions before departure is essential. Public transport to Grimentz is available, but reaching the dam typically requires a car or local shuttle during peak summer months.
Why It Belongs on Every Adventurer’s List
The Via Ferrata Barrage de Moiry stands out for its rare combination of accessible location, bold exposure, and jaw-dropping alpine atmosphere. It delivers a true vertical adventure without requiring a full mountaineering approach, making it an unforgettable experience for those seeking a balance of challenge and scenery. Few via ferratas offer such dramatic contrasts between rugged cliffs, glacial ice, and crystal-blue waters—all within a compact and well-protected route.
