The 2.2 km long trail gives you an insight into the history of the ancient water courses of Valais, known as "suonen" or "bisses". There are information boards all along the very interesting one-hour walk. The start of the footpath is about 45 minutes' walk from the church in Mase or you can drive by car along the "Route des Mayens" as far as the "Bisse de Tsa Crêta".
The careful planning of a tour will ensure that you also derive the maximum pleasure and enjoyment from it. Please take the time to contact the local information centre and enquire about route and weather conditions before setting off. Your intended trail may be fully or partially closed, depending on the time of year and weather conditions.
