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.

Former railway bridge over the Nantes–Brest Canal

Highlight • Bridge

Nice crossing of two long-distance cycle routes: the Vélodyssée coastal route which runs along the Nantes to Brest canal and the track between Saint-Malo and Rhuys which takes the old railway bridge.

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…

What is luck? A target? A condition? a way?
A superlative, not capable of improvement, unattainable? That would be unsatisfactory.

A state is fragile, changeable at any time, "as won as it is gone", also unsatisfactory.

A target . . . reached . . and then? Are you then unhappy?

There is probably no better way to get to know a country and its inhabitants than to travel slowly by bike or on foot. The mutual helpfulness, intense moments, the exchange and a gift, natural smile and nod. Cycling trips make me happy, especially with my companion.
