Grand Bisse de Lens
It takes its waters from the Lienne River, watering the pastures and vineyards of Icogne, Lens, Montana and Chermignon. Taking a vertigo-inducing path, it leaves the Lienne Gorge and crosses the village of Icogne in an underground conduit, skirts the Châtelard hill in corbelled structures which are either concreted or cut into the rock, and finishes at Diogne. A walkway made of wooden boards supported by metal pilons has been constructed above the sheer drops.
