Bisse de Sion and Bisse d’Ayent Walk, Valais, Switzerland

As I was about to set off to do this walk yesterday, Jude said to me “Be careful!” I replied saying that there was nothing to worry about as I wasn’t going anywhere precipitous or dangerous. Er… WRONG!!

My plan was to pick off another of the many bisses or watercourses in the Valais. This time it would be the Bisse de Sion but, to make it into a loop, I would return via the Bisse d’Ayent (previously posted here). As you can tell, I wasn’t expecting any difficulties (or any snow) as bisses are generally flat and the Bisse de Sion runs at a height of around 1,750m (5,740ft) on the south facing/sunny side of the Rhone valley. Put into context, my walk on Friday was at a height of 2,000m (6,560ft) and there was only a few inches of snow.

Everything was going as expected until I was about half to Lac de Tseuzier. OK, there had been a bit of snow in the very shaded areas, but nothing to indicate what was to come. Picture 11 shows where I first encountered some significant snow but this was quickly overcome. However, there were two much bigger challenges waiting around the corner (shown in pictures 17 to 21). Thankfully the snow was well packed and the air temperature sufficiently high to make it easy to stamp solid footholds in the top of the snow. Also my new cross-country trainers have a series of studs which added to my confidence in getting around and/or over these obstacles.

If you look closely at the centre of picture 21, you will see my ‘steps’ down in the snow. It looks dangerous, but I can assure you there were some very good hand-holds on that rock to the right, otherwise I would never have attempted it.

From then on, although there was some more snow, it was very easy going and at no point throughout the walk did my feet ever sink in above the level of my shoes, let alone my ankles. When I reached the ski parking area at Les Rousses, the signs indicated that the road and my route through the tunnel was closed. (See pic 24). So, having had enough challenges for one day, I turned about and walked over 2km (1.5 miles) down the road until I found a path which led me to the much lower and snow-free Bisse d’Ayent. This did at least allow me to get a sort of bird’s eye view of the Bisse d’Ayent. (See to the right of pic 27).

I should also have mentioned in my previous post on this subject that the Bisse d’Ayant is such an iconic example that the Swiss have decided to put a picture of it on their 100 Swiss franc note. That’s about 110 US dollars or 85 UK pounds. (I’d include a picture but I’m afraid I haven’t got one!)

    • Yes, I was very surprised to see THAT much snow. And you are right, mountains are dangerous places and we often read of people slipping to their deaths. I shall be taking it easy over the next few weeks and only going where I know there are no sheer drops!
