Route Description
The adventure begins near the Berneuse cable car area, followed by a short approach that quickly reveals the imposing limestone face of the Tour d’Aï. The route starts gently, leading into a series of cables and metal rungs that gradually increase in difficulty. Climbers soon face the first major vertical section: a sustained ladder-assisted wall offering both physical effort and spectacular exposure. After this, the route transitions into a traverse across a steep cliff, secured by steel cables and punctuated by small ledges.
The second half includes more technical climbing, with narrow ledges, short overhanging sections and several ladders fixed directly into the rock. The higher you climb, the more expansive the views become—Lake Geneva, the Vaud Alps, and the jagged peaks above Leysin. The final push leads to the grassy ridge just below the Tour d’Aï summit, where a short walk brings you to the panoramic viewpoint.

Difficulty and Required Skills
The Via Ferrata Tour d’Aï requires good physical fitness and confidence on exposed terrain. Although technically straightforward, the verticality and length of the route demand endurance, stable footwork and an ability to remain calm on steep sections. Climbers should be familiar with using a via ferrata lanyard system and comfortable with heights. Beginners can complete the route with guidance from an experienced companion or professional instructor.
When to Go
The ideal season runs from June to October, depending on snow conditions. Summer offers stable weather and dry rock, while early autumn provides clear visibility and cooler temperatures. The route should be avoided during rain, storms or after recent snowfall, as the limestone becomes slippery and dangerous.
Access and Logistics
The route begins above Leysin, accessible by road or train. Most climbers choose to take the cable car to the Berneuse area to reduce the approach time. From the cable car station, a marked trail leads to the start of the via ferrata in approximately 20–30 minutes. Descent options include the standard hiking path returning to the cable car or a longer loop towards Leysin on foot. Parking is available in Leysin, and public transport connections are frequent.
