Des moulins aux centrales : les réseaux de l'eau eau dans la vallée de Chamonix

In days gone by, the Chamonix valley was alive with the sound of the many "mills" set up along the Arve. Today, hydroelectric power stations have replaced the old mills and continue to harness the energy of water. This is the story that will be told to you as you stroll along the little-traveled paths and streets of the valley floor. Reservations at the Valley Tourist Office by 5pm the day before.
