Hike Bisse de ChervéDepuis le sommet du télésiège de Combatseline, rejoignez le tracé du bisse de Chervé, en direction de Cleuson. Le bisse de Chervé est le plus haut et le plus alpin des bisses de la région avec un tracé entièrement au-dessus de 2'200 mètres d'altitude. Il n'est aujourd'hui plus en eau et comprend quelques passages vertigineux ou escarpés.
Après environ 45 minutes de marche effectuées le long de ce bisse, vous pourrez admirer le barrage de Cleuson et son eau turquoise. Longez le barrage sur ce même petit sentier jusqu'au croisement avec un chemin plus large au lieu-dit «La Gouille».
Ici, les plus courageux continueront à gauche pour rejoindre la cabane St-Laurent. Les autres auront la possibilité de prendre à droite pour entamer la descente qui commence en suivant la route qui longe le barrage.
Traversez le mur, puis tournez à droite pour prendre le petit chemin escarpé qui descend en zigzag sous le barrage.
Une fois au pied du mur, suivez les panneaux indicateur direction «Siviez».Barrage de Cleuson été 2022 (Michael Meusburger)Randonnée bisse de Chervé été 2021 (Florian Bouvet-Fournier)Bisse de Chervé été 2021 (Florian Bouvet-Fournier)Bisse de Chervé passerelle bois été 2021 (Florian Bouvet-Fournier)Bisse de Chervé Nendaz (Florian Bouvet-Fournier)Balade bisse de Chervé maisonnette été 2018 (Florian Bouvet-Fournier)Barrage de Cleuson mur Yasime Gaudin 2015 (Yasmine Gaudin)2236.9970703125CombatselineIn both summer and winter, Combatseline can be reached by the chairlift from Siviez. Its restaurant, with delicious traditional dishes, is the perfect place to relax before hitting the slopes or setting off on a hike.
In the summer months, it is also possible to reach it on foot. From there, enjoy a hike towards the Cleuson dam on one side or Veysonnaz on the other by following the Bisse de Chervé, the highest of the bisses in Nendaz, winding along at an altitude of over 2,000 metres.
Once the snow has fallen, you can also reach Combatseline via a ski touring route. This is also a great way to reach the different slopes of the ski domain.Restaurant_Combatseline_2015 (Yasmine Gaudin)Restaurant de Combatseline terrasse 2017 (Florian Bouvet-Fournier)Ski restaurant Combatseline 2019 (Etienne Bornet)Restaurant Combatseline été vue 2017 (Florian Bouvet-Fournier)2242.1823730469Bisse de ChervéBuilt in 1862, the Bisse de Chervé is the highest and most alpine of the bisses in the region. It takes its source at 2,370 metres above sea level and runs at an altitude of more than 2,200 metres throughout its entire length, offering breathtaking panoramic views of the surrounding forests, the Rhone Valley and the turquoise waters of the Cleuson Dam lake.
Although the water no longer flows there, some evidence still bears witness to the titanic work carried out to dig this channel linking Cleuson to the mountain pastures of Thyon, the construction of which was intended to allow irrigation of these pastures. Some elders say that its use only lasted a few years, while others say that the water never flowed over the entire route... We'll never know the full story !
In any case, despite the fact that the Bisse de Chervé has been abandoned for many years, it is still possible to follow it thanks to its well-maintained hiking trail. What luck !
A BISSE, WHAT IS IT ?
The bisses were originally irrigation channels that diverted water from the rivers to water the farm land crops growing on the mountain slopes. They are true historical relics and bear witness to the Valaisans' relentless fight against drought. It is their construction that makes them so special. Indeed, these channels had to adapt to the different terrain and environments encountered along the way, giving rise to impressive workmanship, especially when we imagine what the means of construction were at the time. The bisses of our region take their source from the Printse, a river that flows along our valley. Of the eight bisses located in Nendaz, six still have water flowing within their banks and are still carrying out their original task of irrigation.Bisse de Chervé Nendaz (Florian Bouvet-Fournier)Bisse de Chervé été 2021 (Florian Bouvet-Fournier)Bisse de Chervé passerelle bois été 2021 (Florian Bouvet-Fournier)Bisse de Chervé 2020 (Florian Bouvet-Fournier)Bisse de Chervé 2018 (Florian Bouvet-Fournier)Bisse de Chervé barrage cleuson 2020 (Florian Bouvet-Fournier)Bisse de Chervé foret 2020 (Florian Bouvet-Fournier)2162.0810546875Cleuson DamBuilt between 1947 and 1950 and first commissioned in 1950 for hydroelectric purposes, the Cleuson dam was decided and built in an economic context of war. It is a dam with reinforced buttresses, the federal authorities having then required that the building be massive and resistant to bombardments.
Located at al altitude of 2’187m, it holds about 20 million m3 of water coming from the entire valley. Its imposing wall, 420m long and 87m high, stands in the middle of a breathtaking alpine landscape . This site bears witness to a perfect harmony between nature and human activity. What a sight to behold !
WHY IS IT WORTH THE DETOUR ?
In addition to its impressive wall and the magnificent landscape that surrounds it, a walk along the Cleuson dam lake unveils loads of interesting information. Indeed, if you are interested in this subject, in addition to the information posts located in the surroundings, guided visits of the dam wall are also proposed, in order to discover it from the inside. Not to be missed !
ADVICE FROM THE LOCALS
Have your camera or Smartphone ready to capture the turquoise blue water. In fact, the water of the lake is tinted with this exceptional colour, known as « bleu de Cleuson » which is due to the refraction of light on the sit. A ‘must’ for photo enthusiasts !Bisse de Chervé Cleuson automne 2021 (Suisse Tourisme - Dominik Baur)Randonnée barrage de Cleuson automne 2021 (Suisse Tourisme - Dominik Baur)Barrage Cleuson VTT Route Été 2017 (Florian Bouvet-Fournier)Barrage Cleuson VTT Été 2017 (Florian Bouvet-Fournier)Barrage Cleuson (Maude Gaudin)Barrage Cleuson (Florian Bouvet-Fournier)Barrage Cleuson (Florian Bouvet-Fournier)2238.86328125Restaurant de CombatselineA 10-minute chairlift ride from Siviez takes you to the Combatseline restaurant, nestled in the heart of a stunning setting.
