Park in the gravel car park 200 metres to the right after the hamlet of Chiprey (D139). Information point.
(S) Start on the gravel path and, after crossing a small wooden bridge, turn left towards Les Chandeliers (blue and yellow signposts). Leave a path on your left and continue to the Source de Brue, a spring in the middle of the forest with a long basin and two large pools (picnic area and information point).
(1) After the spring or Fontaine de Brue, follow the small tarmac road straight ahead. Leave a road on your right and continue to the crossroads at the entrance to the village of Eternoz, where there is a sign for a plastics factory.
Then turn right towards Nans-sous-Sainte-Anne. Leave the factory buildings on your right and take the path opposite that descends towards Nans-sous-Sainte-Anne (blue and yellow markings). After the second bend, you will come to the Ruisseau de la Vau.
(2) Take the hairpin bend to the right and follow the stream to where it joins the Lison.
(3) When you reach this confluence, take the path on the right that runs alongside the Lison until you reach the small wooden bridge just before the car park where you started.
