A pleasant little circuit that nevertheless includes a sharp climb at the start. The shade provided by the Forest of Planbois can be very welcome.
Direction of travel: clockwise
Landmarks and connections: Armoy (junction with Tour du Mont d'Hermone n°29 and Tour du Roc d'Enfer n°37); Draillant (junction with Tour du Mont d'Hermone n°29 and Circuit de la Vallée Verte n°28); Jouvernex (junction with Circuit du Bas Chablais n°31)
Description: Planbois is a hilly forest dotted with wet meadows at the foot of the Mont d'Hermone massif. Its ecological wealth is remarkable. More than 2,000 species of mushroom can be found here, as well as the rare Gladiolus marais and numerous orchids. The fauna is equally rich, with the reintroduced European beaver, the yellow-bellied toad, newts and salamanders.
Before crossing it, you'll have climbed to the foot of the massif, via the RD26 to Armoy, before starting the long descent to this famous forest. You'll probably only see its conifers, oaks and aspens, but you'll be reminded of all that's hidden inside!
At the end of the forest, in Jouvernex, you'll be on Circuit du Bas Chablais n°31, which takes you back to Thonon via Anthy and Corzent beach.
