Vélocéan

Highlight • Cycleway

Parallel to the Vélodysée route, the Vélacé connects the towns on the Loire-Atlantique coast, from Mesquer in the north to Bourgneuf-en-Retz in the south. Superb panoramas are available along the Vélacé cycle route. The route oscillates between the seafront and the hinterland over 140 km from Saint-Nazaire to Piriac-Sur-Mer. It allows you to discover the unique landscapes and historical heritage of the Loire-Atlantique coastline.

Les Moutiers-en-Retz Beach

Highlight • Beach

Long sandy beach, interspersed with fishing piers, stretching north and south for several miles. A nicely paved trail runs along most of the distance. Here a pleasant picnic space with tables and seats invites to take a break.

Pré Vincent Beach

Highlight • Beach

Facing south, Pré-Vincent beach is cut by numerous groynes of wood or rocks. At low tide, the sea retreats several kilometers and gives way to the famous mud from the Bay of Bourgneuf. Near the town center of Moutiers en Retz, the beach is bordered by a promenade exclusively reserved for pedestrians. Pretty silted walk when I hiked it.

Chapel of Prigny

Highlight • Religious Site

Prigny, is actually the old village of Moutiers-en-Retz, and this chapel was the first church of Moutiers, because until the end of the Middle Ages, Moutiers were only a simple suburb of Prigny. Located on the former shore of the Gulf of Machecoul, Prigny was then a fortified town overlooking the Breton marshes.
This building is now called a chapel by the inhabitants, simply because of its small size. Dating from the 11th century, the chapel of Prigny is a squat building in the primitive Romanesque style.
It is currently the subject of a restoration program.
