Col des Planches - La Tzoumaz

During this first stage, you will discover part of the Old Saxon Bisse (the longest of the bisse: 26 km from its water source in Siviez to La Boveresse). The bisse starts at the point (6). Built in the 1850s, the pipes no longer exist, so you will have to wait until you reach La Tzoumaz to finally see water flowing along the path. The bisse is currently being restored in sections.

This walk is part of a multi-day hike: From Col des Planches to Grimentz via the bisses trail

Description of the walk

Most of this hike follows the Chemin des Bisses trail. On maps, including OpenStreetMap, it is marked as "Chemin des Bisses N°58" or "Col des Planches Vercorin". At each major intersection, you will see signposts with the number 58 on a green background. View this image

(S) From the small car park at Col des Planches, head towards the Col du Lein road. Follow this small road until you reach a small farm (several buildings).

(1) Go around the farm on the left and continue towards Col des Planches Vercorin. You will reach a crossroads.

(2) Continue eastwards. Pass the Col du Lein car park

(3) Head north, following the sign for "58". Pass a building at the end of the Col de Lein. Continue along this road until you reach a junction with a track.

(4) Take the path that descends to the left (signposted 58). Continue on the "Col des Planches Vercorin" and cross another small road.

(5) Continue along this road until you reach a hairpin bend.

(6) At this point, the trail enters the woods and is also called "Ancien bisse de Saxon". Signpost (58). Continue along this trail, which climbs steeply at times. The trail levels out a little and crosses a path coming from the top of the ski lifts, which is used by mountain bikes.

(7) Continue north-east on trail 58 "Col des Planches Vercorin".

(8) Leave the descending track on your left and you will finally see the restored Saxon bisse with its irrigation channel. From points 6 to 8, only the path along the irrigation channel remained. The channel had disappeared at the beginning of the 20th century. It is only as you approach La Tzoumaz that the bisse has been restored in sections.

(9) Leave the bisse on your right (you will come back to it in the next stage) and start the descent towards La Tzoumaz by turning left (north-west).

(10) Leave the track and follow the path on the right that leads to the cable car station.

(11) Opposite the cable car station, take the small path down to the centre of La Tzoumaz (Hôtel de la Poste) (E).

It is possible to reach the Col des Planches by "le Bus Postal".
Please note that for most timetables you need to request a reservation 48 hours in advance at the following email address: valais@carpostal.ch

That's enough, I think

Hello Nathalie,
I don't know how to include it in the practical information, let me explain:
When I prepared and carried out this 6-day hike, my concern was precisely how to get from the starting point to the finishing point.
The day before, I arrived in Martigny and went looking for the bus to the Col des Planches. I spoke to the bus driver, who explained the booking option, but not for all timetables, as the line is not very busy up to the terminus. I decided to park my car at the Col des Planches and come back to pick it up a week later. As a result, I didn't have to be at the Col des Planches at any particular time, and what's more I was able to meet the 48-hour booking deadline.
To come back to the information and what to remember:

  • To insist that you prepare the journey to the departure point well in advance.
  • I can't guarantee the telephone number in the long term, as it was true last year.
  • Only the e-mail address is probably still valid.

In short, the only reliable information I could provide would be:

It is possible to reach the Col des Planches by the "Postal Bus".
Please note that for most timetables you need to request a reservation 48 hours in advance at the following e-mail address: valais@carpostal.ch

As for the rest, transport in Switzerland works very well.
I was able to get to Martigny from Grimentz by the Grimentz-Vissoie and Vissoie-Sierre buses, and by the Sierre-Martigny train.

Another point: Parking your car at the Col des Planches is a good idea, as parking for a week in Martigny is prohibitively expensive.
All the best,
Dominique

Hello Dominique,

Thank you for that clarification. In any case, the post bus remains a very practical option for a hike with no return at the start. Having had to interrupt the route because the weather was too bad, we had no trouble getting back to Martigny.
(More next year)
Sincerely
Catherine

Hello Catherine,

Having chosen to take the postal bus to the Col des Planches, it's worth noting that at this time of year, the bus stops at Chemin dessus,

It's not just in this season: in summer too, there are very few buses that go as far as the Col des Planches.
I did this route in July 2019 and chose to park my car at the Col des Planches. Only on the way back from Grimentz did I have the same problem getting my car back. When I spoke to a post bus driver, I learned that at certain times you could get a lift up to the Col des Planches, but you had to book in advance. You need to plan ahead and check which timetables are subject to booking, call 058 386 95 00 or contact valais@carpostal.ch 48 hours in advance.
All the best,
Dominique

First of all, thank you for suggesting this hike. We only had difficulty arriving at La Tzsoumaz, where we probably left the track too early.
Having chosen to take the postal bus to the Col des Planches, it's worth noting that at this time of year, the bus stops at Chemin dessus, so the hike is 3 km longer, which we covered on a very lightly used road.
