But tell me, this Saint-Guérin lake doesn't look like a small mountain lake… Why is there so much water here? How did she get there? Come as a family to find the answers to all these questions and many more, in a grandiose landscape.

Do you feel more like a drop of water rushing in the current or rather an engineer in charge of the titanic construction site of a dam?

When you have chosen your destiny (for the day), equip yourself accordingly and set off on the journey of adventure!

If you opt to follow Guérinette the droplet, with your game bag, you will have to rack your brains a bit and show some imagination along the way.

But what are these barbaric things such as: hydroelectricity, a penstock, an impoundment? You will learn it while walking along the water reservoir.

Sensation guaranteed by crossing the Himalayan footbridge which spans the lake! it rocks a little… but it's so cool to walk above the water.

If you choose to take on the engineering challenge using your tablet or smartphone, then you'll have to rack your brains in order to erect the dam.

It's fun to see how the valley was before being covered by these millions of cubic meters of water.

A little further on, a torrent rushing down the slope will bring you some freshness. And here you are back, unbeatable on arch dams!




Take part in the construction of the Saint-Guérin dam, in the shoes of an EDF engineer, with whom you will discover all the specificities of this profession and the steps to arrive at this wonder of Beaufortain (from 12 years old).

The game kit is on sale at the tourist offices of Arêches and Beaufort
