This old ruined mill is unfortunately not very visible due to the numerous weeds that hide the building.

This sunken and very shaded path connects Kerantré to Moustoir, just in front of the Vilaine. Be careful because, in rainy weather, it can be difficult to walk along (muddy ground with a high risk of slipping).

Milestone marking the boundary of the Abbey of Prières. Created between 1248 and 1252, it was located in Billiers, near the Pointe de Penlann. The abbey was largely destroyed during the Revolution. There are still a few buildings, the bell tower and a few milestones at the boundary of its domain. This milestone is the easiest to find: it is decorated with a Macle (heraldic symbol) and an Ermine (symbol of the Dukes of Brittany who founded the abbey).

The Foureux footbridge allows you to pass from Beganne to the commune of Marzan, and to reach the La Roche Bernard bridge by paths that are perfectly usable by bike.
