In Nendaz, families can discover the diversity of the region on a treasure hunt along traditional irrigation channels.

Young treasure hunters should first go to the Nendaz tourist office with their parents to collect a small brochure and then they can head off on the trail. The route takes families along the Bisse du Milieu and Bisse Vieux water channels. Along the way, children will come across posts with puzzles to solve. If they answer all the questions correctly, children get a souvenir to take home.
