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 don the mountain for irrigation of the lands. The traces of the ancient bisse are still good visible in the landscape. The bisse is hewn out of the rocks of the mountain and gives you extraordinary views over the valley, ravine and mountains. This is certainly not a trail for persons afraid of heights. After we leave the Bisse du Ro we 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 we head back to Crans, we take the lower path beneath the Bisse de Ro in the direction of Bisse de Lens. From this trail you get an other whole look of the valley and mountains. We end with a steap climb towards Crans-Sur-Sierre
