On the "Chemin des Bisses" in the Val d'Anniviers

Monday Sept.7th -- Whereas the rest of Switzerland wasn't having great weather on Monday, in Canton Valais the run of good weather had already started, so we decided to head down that way for three days. The main plan was a 2-day round hike to the Moiry Glacier with an overnight in a hostel perched high next to the glacier.

But getting to the Moiry Lake at the end of the Val d'Anniviers is five hours travel for us, and after five hours in public transport I don't like to start a long hike. So we booked a hotel in Grimentz, a popular vacation town at the back of Val d'Anniviers and just 20 minutes by bus from the lake (so we would start our Moiry Lake Hike on Day 2), and for Day 1 we would start in the Rhône Valley at Vercorin, and walk INTO the Val d'Anniviers.

The fastest way to get to Vercorin is by cable car, and from there we followed a section of the "Chemin des Bisses" (a 100-km regional trail which follows several of the historical irrigation channels along the Rhône Valley) for about 12 km to the village of Mayoux, from where it was going to be a short 20-minute bus ride to our hotel in Grimentz, instead of the 70 minutes it requires for the full bus ride from Sierre. (As it turned out, they had started construction on the road that day, and we had to walk an additional 30 minutes to Vissoie to catch the bus that runs the detour to Grimentz).

In any case, a very interesting hike high above the valley, along the ancient irrigation channel called "Bisse des Sarrasins" (abandoned in the mid 1800's probably due to the loss of too many lives during its upkeep). Since 2004, the Association of the Bisse des Sarrasins has been working on the resurrection of this irrigation channel by restoring its original route based on the findings of various iron pegs and wooden structures used for the channel at the time of its estimated construction in the 14th Century. The source of the irrigation channel has been pinpointed to just below the village of Pinsec (a cute little village requiring a 200m climb to get to), and the 10-km channel brought precious water from the Anniviers Valley to the Briey Plateau on the side of the Rhône Valley just below Vercorin.

Always some interesting things to discover!

Heading down to the start of our trail, toward the Val d'Anniviers

Our trail along the Bisse des Sarrasins first goes into the Crouja Ravine, then via Pinsec to Mayoux. (Definitely more like 4 hours to Mayoux). From there we would have had a 20-minute bus ride to our hotel in Grimentz, but they had started construction on the road, exactly on this day! So we had to walk an additional 30 minutes to Vissoie across the valley to catch the "detour" bus.

4 hours to Mayoux, then another 30 minutes to Vissoie, where an extra bus takes the detour route to Grimentz. It was supposed to be a short hike! 13 km. Trail no.58 is the "Chemin des Bisses" and follows the various side valleys of the Rhone Valley.

Heading into the Crouja Ravine. Behind me is the road into the Val d'Anniviers. It is a long bus ride from Sierre to the back of this valley.

On the South side of the Crouja Ravine is the abandoned part of the irrigation channel which first had to be discovered before the trail could be restored.

We ran into a sign that offered an "Easy Way", but we of course chose the "Hard Way"

Along the "Easy Way", we would have missed this view across to the North side of the Ravine, where you can see how the Bisse des Sarrasins was originally hewn out of the vertical cliff to transport the water out of the Anniviers Valley.

Very close-up view of the planks that the residents of the valley had to walk, to keep the irrigation channels clean. This section of the "Bisse" is privately owned, and you can pay for a guided walk along the planks, with climbing gear to attach to the cables.

shows how once can walk along the planks on the opposite side of the ravine!

On the other side of the Val d'Anniviers is the road that goes to the back of the valley.

As we exit the Crouja Ravine, a wonderful view to the back of the Val d'Anniviers. The fantastic peaks at the back (including Zinal Rothorn) are unfortunately covered by clouds on this day.

The start of the fun part of the hike. For the next 3 km or so, the trail consisted of these beautiful bridges along the steep cliffs (lots of rocky debris on the planks from crumbling rock walls)

Walking along the interesting bridges which replace where the original irrigation channel would have passed through (it is estimated the channels followed this path, by remains of the original constructions that they have discovered along here).

Following where the original irrigation channel would have been built

Across the valley is a small hamlet perched on the steep mountain flank. It is called FANG, and you can get to it by descending to the river below (or from the main road above)

This sign is interesting. Besides the horrendous translation from French (especially to German), it warns that the trail becomes technical from here, and that "corpulent" people should take the detour..... especially because of Part 3: "Passage à quatre pattes" or "Way on all fours"

"Section 3" according to the map, "Way on all fours": Now we know why "corpulent" people were advised to take the detour!

Wildlife of the day

From information placards along the way, we learned that this "damage" on the trees is caused by woodpeckers.

Way up high on the other side of the Val d'Anniviers is the relatively large town of Chandolin, one of the highest villages in Europe occupied year round.

Near this point, before a humid and exhausting ascent to the hamlet of Pinsec, is where they believe the water for the irrigation channel had its source, from the Pinsec stream which descends from the peaks along which we are walking.

Glad to arrive in Pinsec. We had only a few minutes to admire the historical buildings, as we were hoping to catch the 16:20 bus in Mayoux, next town to the South (30 minutes)

Very pretty, hamlet of Pinsec. The irrigation channel (Bisse des Sarrasins) was built approx. 200m below the village.

As we rushed down the trail toward Mayoux, this is a photo of Vissoie on the other side of the Valley. We had 20 minutes to cover the 30 minutes to the bus stop in Mayoux!

We just made it on to the bus in Mayoux, the one headed to Grimentz. But the bus driver told us the road was closed, and she wasn't going that far, we had to cross the river to Vissoie for the detour bus. There is no information in the bus schedules that this detour is taking place!!!!

After a 12-km walk from Vercorin to Mayoux, we had to cross the valley to Vissoie to catch the detour bus to Grimentz. An additional 25 minutes, but it gave us a chance to look around the village of Vissoie.

Main square in Vissoie. Here is where we catch the bus (in and out of the Val d'Anniviers). As Urs waits below, I took a quick look around the main part of the town.
