This trail follows the municipal boundaries between the villages of Chalèze, Montfaucon and Gennes. You will arrive at the Fort des Epesses, a military building constructed in 1883 to prevent the enemy from passing through from any direction and from bombarding the central square by keeping it out of cannon range. When the weather is fine, you can enjoy views of the Jura and Mont Blanc ranges.
