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.
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).
