⚠ Exceptional closure: this activity is closed for the moment and until 1. Mar 2026.
An extraordinary moment at the Mont-Soleil Astronomical Observatory.
Who doesn't dream of discovering the secrets of the universe? The observatories, including the one at Mont-Soleil, allow us to get closer to the stars by observing the sun and the stars through a telescope specially designed for this purpose. And in case of bad weather, the planetarium even allows visitors to visit all the corners of the universe with their feet firmly planted on the ground.
The different visits can be found under ''Links & PDF'' or ''Details''.
