Built before 1430, the bisse of Torrent-Neuf (also called bisse of Savièse) was once the most daring irrigation project of its kind. It was sourced from the river Morge, leaving its gorge by a very precipitous and undulating route, and it provided an abundant supply of water. Our suggested walk covers an elevated path which has been newly restored. The purpose of this type of refurbishment work is to remind us of the scope of the task undertaken by our ancestors.

A part of this fairly challenging circular hike follows the bisse Mont d’Orge. First you climb up the mountain Mont d’Orge where the ruins of Mont d’Orge Castle and the statue of Notre Dame are located. On the way to the glittering lake of Mont d’Orge, you will experience great views over the Rhône Valley and the city of Sion.
