Go back in time along the trail of Bisse du Ro to the magnificent artificial lake of Tseuzier. This hike leads you along the old Bisse du Ro to the Rawyl Dam and back in the direction of Bisse du Lens to Crans. The Bisse du Ro is an old irrigation waterway build in the 15th century for bringing water down the mountain for land irrigation. The traces of the ancient bisse are still visible in the landscape. The bisse is created out of the rocks of the mountain and gives extraordinary views over the valley, ravine and mountains. This is certainly not a trail for visitors who are afraid of heights. After leaving the Bisse du Ro head to the Rawyl Dam where the big lake "Lac de Tseuzier" is situated. It collects the melting water of the snow and generates electricity. The dam was build between two mountain walls with an amazing rock structure. When heading back to Crans, take the lower path beneath the Bisse de Ro in the direction of Bisse de Lens. From this trail you get a new view of the valley and mountains. End with a steep climb towards Crans-Sur-Sierre.

Fantastic hike - one of the most stunning paths I've ever put my feet on. be aware the trail is closed at the moment a few kilometers in, but those first few are worth doing anyways!
