In 1865, work began on the longest bisse (alpine irrigation canal) in Valais. Stretching over more than 32 kilometres, the Saxon Bisse took its source from the Printse River in Nendaz, flowing to Saxon to irrigate the numerous orchards and crops.
Starting from Siviez, crossing the upper reaches of the communes of Nendaz, Isérables and Riddes, you can discover the mountain pastures of Tortin as well as the larch forest of the Dzora mayens. At the end of the route, after some 26 kilometres of walking, you will arrive at La Boveresse, situated above the Saxon plain.
The bisse is in water from the end of May to mid-October.
No particular difficulty
