castle Tourbillon and ruin Valère / Source: ©ottergraafjes

Tourbillon castle and Valère ruins

The castle of Tourbillon and the ruins of Valère both stand on a hill and are therefore clearly visible from all sides. Tourbillon dates from the 13th century and Valère was built somewhere between the 11th and 13th centuries. In 1788 there was a serious fire in Zion. As a result, Tourbillon was completely destroyed. Due to political unrest, it took a very long time before the castle was rebuilt. Since 1907 it has had the status of a historical monument.

Walks along suonen/bisses

It does not rain much in this region and yet the various crops need water. The farmers get this water from an artificial canal. Such a channel is called a suone (German) or bisse (French). These canals are very old and some are dilapidated. Some suons have been renovated especially for tourists, so that it is possible to take a walk along them. There are various walks along these water supplies throughout the canton of Valais. Some walks are easy to do, others are quite challenging. It is wise to wear good shoes for all walks.

Grande Dixence/Lac de Dix

The Lac de Dix reservoir is located in Val dHérens. That is a side valley of the Rhône Valley. To get here you have to drive in Vex towards Val d’Hérémence. This reservoir is the highest reservoir in the world. The wall of the dam (Grande Dixence) is approximately 285 meters high. Construction work took place between 1950 and 1961. The reservoir was put into use in 1961. This reservoir collects the meltwater from 35 glaciers. This amounts to a water capacity of 400 million cubic meters. This meltwater is supplied through tunnels with a total length of 100 kilometers. It is possible to take a paid tour inside the dam. There is a cable car to the dam. Even if you don’t want to visit the sheet pile wall itself, it is still worth going here. You have a beautiful view and for those who like walking, it is possible to walk along the lake or even further to the hut, Cabane de Dix.

Pyramids of Euseigne

A beautiful natural phenomenon can be seen in Val dHérens. Those are the Pyramids of Euseigne. These pyramids are earth pyramids and were created during the Würm Ice Age (80,000 to 10,000 years ago). They are 10 to 20 meters high and some pyramids have a boulder on them. If you follow the road to Euseigne you will see the pyramids appear automatically. The road to the village of Euseigne goes straight through the pyramids.


Not far from Sion, near Vétroz, a road goes towards Derboranche and Col du Sanetsch. At some point the road splits. You must keep left to drive towards Derboranche. You will then eventually arrive in the Derboranche valley. Anyone who finds it scary to drive on very narrow roads should not go to Derboranche. The road to it is quite narrow. In some places you can’t pass each other. The road there is beautiful. On the left you see a deep abyss. Every now and then you drive through tunnels and you may come across a Swiss post box. It is wise to sound the horn every now and then in the tunnels, so that any oncoming traffic knows that someone is approaching. The road to it is approximately 11 kilometers long. At the end of the road you cannot go any further. There is a parking lot and then you can continue on foot. It is nice to walk around Lake Derboranche. Somehow the lake is getting smaller every year.

A landslide occurred twice in the 18th century. Large amounts of rocks fell from the mountains of Diablerets. This created the lake. The mountains were even given the name Duivelsbergen, because at one point it was thought that the landslides were caused by something evil.

Col du Sanetsch

This pass is located at an altitude of 2,044 meters. One side is in the canton of Valais, while the other side falls under the Bernese Oberland. A cable car goes up from that side. The road to it is beautiful, but it comes to a dead end at the end. Here you also pass through a number of tunnels. The higher you go, the fewer trees. At a certain point you end up above the tree line. The road is not open all year round. The winter closure applies from October to May. Here you will find unspoilt nature and with a bit of luck you will see murmeltiere (mountain marmots).

So ideal for a winter sports holiday. In addition to skiing, you can take beautiful snow walks in winter. There are several ski areas in the area.

Originally they were two different villages, namely Crans and Montana. In the end it became Crans-Montana. It is a fairly fashionable winter sports resort and is located at an altitude of 1,500 meters. The ski area goes up to an altitude of 3,000 meters. There are 140 kilometers of ski slopes. These slopes are divided into blue, red and black slopes. In addition to skiing, you can also go cross-country skiing, hiking (with or without snowshoes) and even bobsledding.
