Park in the car park along the D121 (Montécheroux-Saint-Hippolyte) just after the junction with the D147 coming from Chamsol.
Note: The entire hike follows the yellow and blue markings.
(S/E) Join theGR®5coming from the D147 via Chamesol and begin the descent. You will soon reach a crossroads of paths.
(1) Take the path on the right, walking along the top of the cliffs
Along the cliff there are numerous spots offering panoramic views of the Dessoubre valley and Saint-Hippolyte; feel free to stray from the path, taking care to avoid the cliff.
You’ll reach a natural arch.
(2) Continue along the path, passing under the power line where the height of the cliffs is particularly striking. Carry on until you reach a fence; follow it, keeping it on your right. You’ll emerge at the Grotte du Bisontin.
(3) Descend to a wide path and turn left. Then follow the path through the woods, which is still marked in yellow and blue. You will reach the junction with a forest road that forms part of theGR®5.
(4) Turn left here, then quickly veer right. You will then come back to the original junction further on.
(1) Continue to the right along the path taken on the way out to return to the starting car park (S/E).
