Located at the gates of the Haut-Jura regional natural park, Champagnole is also considered the “pearl of the Jura”. Perched at an altitude of 540 meters on the banks of the Ain, the town is located in a wonderful natural setting. There is also an archaeological museum due to the discovery of remains on Mont Rivel.

Several million years ago, the Ain was lost underground, in a labyrinth of cavities, an underground gallery called "losses". Over time, the work of water erosion has done its work, and has nibbled the limestone and destroyed the vault of the underground gallery. It remains today a unique natural site where water makes its way between rocky piles and stone remains.

The Pont de l'Épée bridge spans the Ain river. When the sun is at its zenith, the color of the water is magnificent. The view of the river and the weir located downstream deserves a short break.

The Vilain Castle was demolished in 1810 to make way for factories, a sad end for a castle designed in 1186.
