Canal de Nantes à Brest

Highlight • Other

In sections between locks the Blavet River is almost left to it's natural wild state, though the invasive plants choking its flow probably can encroach faster due to the slower, regulated flow speed

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.

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.

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.
