Most of this hike follows the Chemin des Bisses trail. On maps, particularly OpenStreetMap, it is marked as "Chemin des Bisses n°58" or "Col des Planches Vercorin". At each major junction, you will find signposts with the number 58 on a green background. View this image
(S) From the centre of La Tzoumaz (Hôtel de la Poste), go to the cable car station.
(1) Passing under the cable car departure point, take the path that initially runs alongside the ski lift and then heads west to rejoin a track.
(2) At the signpost, follow the track south to rejoin the Saxon bisse trail you left the day before. (Signpost No. 58).
(3) Follow the bisse on a gentle uphill slope of about 3%. You will reach a picnic area in Taillay with a water wheel and a hammer powered by the bisse.
(4) Continue following the signs for path no. 58. The trail climbs northwards, passing under the summit of Le Fou (2,610 m) and then under the Dent de Nendaz (2,463 m)
(5) Trail no. 58 finally crosses a track above Isérable. Leave this track on your right and continue along the bisse (the trail branches off to the right, climbing slightly). Continue for about 300m along the old Saxon bisse until you reach a crossroads.
(6) Leave the Saxon bisse. Trail no. 58 turns left and is still called "Col des Planches Vercorin". Descend for about 100 metres, and trail no. 58 joins a new track.
(7) Begin the descent towards Nendaz, pass a dry gully and continue until you cross the Pracondu road.
(8) Cross this road and continue north-east on No. 58 "Col des Planches Vercorin" until you reach the entrance to Nendaz (Route de la Péroua).
(9) On this road heading east, head towards the cable car station.
(10) At the cable car station, turn right to reach your evening accommodation: Hôtel Les Étagnes (E).
