Locks 79 to 87 - Around Saint-Gérand

Highlight (Segment) • Other

Sequence of nine locks, seven of which are very close to each other. Boat traffic must have been very slow on this section…

Just before arriving in Pontivy the river Blavet crashes down a wide cascade, while the canal is channelled left through a lock. Pedestrians and bikers can cross the narrow metal walkway across the barrage and the locks to shortcut to the other side.

Stumo lock on the Nantes-Brest canal

Highlight • Other

The locks at this location with the keeper's house midstream were probably also serving as a mill to harness the water power from the main Blavet river channel.

Lock No. 138 of Bon Repos

Highlight • Bridge

The 18th century canal lock has been shaped like a medieval bridge fitting to the old Abby, with a hostel in the old canal keeper's house, and a café on the opposite side from the Abby.

Bon-Repos Abbey

Highlight • Other

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.
