146 steps, a few steps and narrow passages, an old wooden door, and here you are on the highest terrace in Luxeuil!
The view has to be earned, but once you're at the top, you'll love it. The orientation table will guide you through the 360° landscape: See the 3 little bumps over there? That's the Planche des Belles Filles!
On a clear day, keep your eyes peeled for a glimpse of the Alps!
