This stage, heading south from the Vilaine Estuary, is classed as being for expert cyclists, with a lot of stretches going along the water’s edge. The Pointe du Bile Headland is a great spot at which to stop and appreciate the maritime atmosphere. As to the Bay of Pont-Mahé, with its gently sloping beach, you’ll see how it’s a favourite for learner windsurfers.

Between St-Molf and Quimiac, this stage goes via a series of little canals serving extensive salt marshes, sometimes giving you the impression that you’re riding on water! Not to be missed: the Pointe de Mesquer Headland and two detours, one to the Petite Cité de Caractère of Piriac-sur-Mer, the other to the port of La Turballe. Then you arrive at the splendid fortified medieval town of Guérande.

After enjoying the historic town of Guérande behind its ramparts, follow directions towards La Baule to join the greenway to reach that resort, which lies on one of Europe’s loveliest sandy bays. On the way, stop in Escoublac Forest, a great place to have a picnic and relax. Then it’s not too far before you reach La Baule’s beach, where you might well be tempted to go swimming in the sea.

This stage offers a touch of old-fashioned charm. It also passes by Dissignac’s Neolithic mound before Le Bois Joalland Lake, appreciated by locals for its sports facilities. Before the lake, the way passes through woods and countryside; after it, it becomes more urban. Arriving at the port of St-Nazaire, wide boulevards follow the seafront, and the American First World War monument greets you with open arms.
