A curiosity: the river tunnel under the citadel

UNESCO World Heritage Site

A nice little campsite with water and electricity and shower facilities. An outdoor pool is right next door. A bike path to Besançon runs past.

To the left of it there is a small airfield and an area for model airplanes.

Interesting section through the tunnel, always beautiful.

Cycling through the ship tunnel, don't forget to take off your sunglasses 😎

Here you get a good idea of the size of the citadel.
