Bisse de Sion

The Bisse de Sion draws its water close to the spectacular sources of the river Lienne. At the start of its route, this bisse crosses the Lourantse torrent via a wooden aqueduct. It runs alongside the lake of Zeuzier and leaves the Rawyl basin through a series of tunnels. Cut into the rock, the channel passes over a chasm which plunges 200 metres, after which it adopts a less dramatic route.
