Hiking around Sion
After my retirement, I had a lot of free time, but the feeling of loneliness also grew stronger. Friends were gone, and children were busy with their families. I stumbled upon the website https://www.flirtyon.com/ by chance and was eager to try it out. Adults and understanding people communicate here. I found a good conversation partner with whom I enjoyed drinking tea and having an open conversation.

The Col du Sanetsch is certainly one of Switzerland's classic mountain passes, even though it can only be approached by road bike from the south. There are two alternative routes: one starts in Sion, the other, this one, in Conthey. Above the village of Daillon, the two roads converge and the steeper part of the climb begins. While there is only a parking lot at the Col du Sanetsch, the highest point, you can continue on the paved road to the reservoir (Lake Sanetsch). There is an inn there. The cable car station, which offers a ride down to Gsteig bei Gstaad, is also located here. This makes the pass a perfect circular tour.

The elevation profile of this climb from Sion to the small holiday home settlement of Arolla is somewhat deceptive. While the gradient is modest, at almost 40 kilometers in length and over 1,600 meters in elevation, this climb is quite challenging! The scenery is rich, but the most famous highlight is probably the Pyramids of Euseigne. Whether it would have been possible to build the road directly beneath the rock formations is up to you to decide.

A rocky and austere pass, perched in the Bernese Alps, on the southern ridge of Mont Pucel and the Wildhorn. The pass is a spectacular hiking destination, with surreal geological features, as well as spectacular views of the surrounding lakes, valleys, peaks and glaciers. One side of the pass approach will require some climbing on ladders and cables, which may add a bit of complexity or adventure to the day.

A beautiful, weather-shaped mountain in the Bernese Alps. From the summit you can get an excellent view of the Wildhorn, which is located right next to this peak. The summit sits on a rolling ridge, meaning the route to the summit passes through exciting and somewhat exposed mountain terrain, giving a lovely airy atmosphere and adding to the adventure of the day!
