The Vieux water channel runs alongside a stone staircase. This ingenious section of the water channel allowed the water to continue flowing down to the valley. Here you will find a hand-shaped sculpture, signed Raphaël Pache. This hand receives the water and lets it flow between its fingers to return it to the stream. The sculpture thus suggests that water is only borrowed from the mountain and that we must therefore respect it.

Not only is cycling prohibited here, but even carrying bicycles is prohibited. You are neither allowed to push nor carry your bike! Possibly even possessing a bicycle is a criminal offense. This isn't clearly indicated at the entrance; there's just a crossed-out biker on a bicycle. After pushing our bikes 2km and about 300 meters in elevation to the Col de Cou, we fell victim to state-sanctioned highway robbery and paid 50 CHF per person (July 30, 2025).

It's an anti-must, it's more of a bypass! August 2025 impossible to get to this level.

The Pichioc waterfall is a wonderful place. The waterfall itself is not too huge. The water is very cold and can be turbulent, so if you want to go into the river, cross with caution.

A beautiful and quiet riverside area, close to the towns of La Tzoumaz and Verbier. The wooded area around the river provides much needed shade during the summer months.
