(5) The standard route continues straight on towards Tonny … but it seems that there is now (since 2025?) the option to turn right and follow the A7 walk, marked with Blue Rectangles, which crosses the Bois Cousin (private) to reach Bonnerue via the forest rather than via the cycle path (concrete) between Tonny (6) and Bonnerue (7).
Worth a try… feedback would be welcome if any ‘visorandonneur’ gives it a go!
(11) When we were there, the mapped path leading straight ahead was impassable. We had to take a detour by turning right onto the road and then taking the first path on the left. Its accessibility seems to vary with the seasons and/or from year to year. No big deal. To be checked.
