Path between two bodies of water on the Nantes-Brest Canal

Highlight • Trail

A stretch on the dam before the Trehu Moron dam.

Former abbey now in ruins. Interesting place, in the immediate vicinity of the canal, but plan to cross if you want to approach the abbey because it is located on the opposite bank to the Vélodyssée track.
