Fort Saint-Antoine

Highlight • Historical Site

Built in 1879 to protect the French border with Switzerland, it was finally decommissioned and abandoned. But not for long ! It has been used for maturing Comté cheese for 50 years now!

Trail Reviews

Nancy Callaert 🇧🇪🥾🥾
July 9, 2025, wandeling Malbuisson met La source Bleue

A challenging hike indeed. In a forest with lots of rocks, lots of ups and downs. The route to Le Source Bleue is steeply downwards.
