The pyramids of Euseigne are a geological curiosity in the Val d’Hérens. They are located in Euseigne on the Sion-Evolène road at the intersection of the Val d’Hérémance which leads to the Grande Dixence dam. The road passes under the pyramids through a small tunnel.
Formation of pyramids
Pyramids were formed following the disappearance of the glacier that covered the Val d’Hérens during the last glaciation about 100,000 years ago. As the glacier retreated, it left a compact moraine with rocks. With erosion, the moraine has dug itself under large rocks that compress it and protect it, forming pyramids. These will eventually disappear over time due to the action of water.

Parking lots are available along the road below the pyramids
In 2016, the canton of Valais decided to create a new tunnel around the pyramids by 2021, which will protect the site and improve traffic flow. It is true that today the visit of the place is not easy with a ravine on one side and a dangerous road on the other.
Stroll around the pyramids
The pyramids path starting close to the tunnel and lasting 20 minutes provides a nice observation point.
