Built in the last decade of the eighteenth century, this bisse was constructed on an old railway line used to transport ice from the Trient Glacier to the Forclaz Pass. This ice was then exported as far afield as Paris. There are explanatory educational panels explaining the social organisation and the irrigation rules along the trail.

Departure & Itinerary

The trail starts opposite the restaurant at the Forclaz Pass. Follow the marked path south towards the Trient Glacier. For the return trip you can retrace your steps or pass by the village of Trient. This is a shady and unfrequented trail. There is a little café where the bisse takes water. It is also possible to continue as far as the glacier tongue.

In good weather, the stretch where the bisse takes water is idyllic for a picnic.

Most of the trail is suitable for push-chairs and those with reduced mobility.
