It’s the time of year to enjoy the ‘bisses’ once again
News
Four of our eight bisses are already accessible, offering many easy walks in magnificent landscapes.
The eight bisses of Nendaz form a network which is unique in the world. Remarkable fact, six of these historical irrigation canals are still in operation and so are water-filled in summer. The paths which run alongside them offer innumerable possibilities of hikes which are as accessible to children as they are to seniors. Altogether, in summer they represent 98 kilometres of walks.
BISSES WHICH ARE PRACTICABLE AT THE MOMENT
- Bisse d'en Bas
- Bisse du Milieu
- Bisse de Baar
- Bisse de Salins
FILLING WITH WATER
The bisse du Milieu is filled with water but interruptions can still occur at the start of the season. The other bisses have will have water flowing between their banks very soon. A section of the bisse de Saxon will also be filled with water before the beginning of the summer, as it is every year. The Bisse de Chervé, located at 2'370 m above sea level, is no longer used for irrigation purposes and therefore no longer filled with water. It is usually accessible from the end of June.
BISSE DE VEX CLOSED
The Bisse de Vex suffered significant damage in 2025 following heavy snowfall in April and a debris flow in June. Several sections of the canal were destroyed and footbridges swept away, making it impossible to supply water and forcing the closure of the hiking trail.
Major restoration works are underway and will span two to three years. In 2026, priority will be given to the rehabilitation of the Doussin torrent sector. If conditions allow, a partial reopening of the trail is planned between late 2026 and 2027, with water flow expected to be restored in spring 2028.
