From the Croix du Bois park, you just have to enter the forest to have fun. The paths and trails are technical, bumpy and sometimes steep. The perfect mix for a great mountain bike ride.

La Mérantaise and its washhouse

Highlight • Historical Site

The forest of Port-Royal is distinguished by the pretty landscapes created by the Mérantaise which crosses it. The washhouse set up by the river further embellishes this idyllic setting.
