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…

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.

Guernal lock on the Nantes-Brest canal

Highlight • Other

The Guernal lock is located in the town of Neulliac. It was built around the 1800s and is accompanied by several buildings (houses, stores, bridges over locks) whose restoration has not been completed.

Cascade Lock

Highlight • Bridge

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.

Towpath of the Nantes to Brest Canal

Highlight (Segment) • Trail

New cafe just on the way out of Pontivy owned by a very friendly and helpful gentleman with lots of experience and tips. He will soon have a bike repair station too! Top!

Château de Josselin seen from the Sainte-Croix bridge

Highlight • Castle

Erected at the beginning of the 11th century, the Château de Josselin was once just a simple wooden building. Rebuilt and extended over the centuries, it was modernized by the Rohan family who still live there today.

The castle can be visited and also houses a museum of dolls and toys.

Josselin Castle

Highlight • Religious Site

The castle's imposing towers are reflected in the River Oust. Owned by the Rohan family, one of the oldest families in Brittany, it is the symbol of this pretty town. Plan half a day to stroll through the charming streets of this "petite cité de caractère" (small, particularly picturesque town) and also visit the basilica.

Theme for the day… Minor disaster #2 encountered. Challenge accepted and overcome.

Today was very similar to yesterday in terms of scenery and setting. We continued along the canal for most of the day. There was some variety however. Sometimes we had the canal on our right, and …
