Superb, but very crowded. Ideally, do it off-season and during the week.

This rather improbable monument in its location commemorates the landing of American troops in Saint-Nazaire during the First World War.

A very pleasant crossing of the Loire, especially by bike or on foot. You can take the time to observe the abundant wildlife during the navigation.

The triple lock of Les champs neufs, located in Frossay on the Canal de la Martinière, is a masterpiece of 19th-century river engineering: * A cascade crossing: Unlike a simple lock, this structure comprises three consecutive chambers that allowed ships to compensate for the difference in level and effectively regulate water flow between the Loire estuary and the canal. * The steam machinery: Right next to the chambers stands the stone building of the La Machinerie du canal, which once housed imposing steam pumps responsible for maintaining the canal's water level constant for commercial navigation. * Heritage and promenade: With its lock gates, metal bridge, and preserved period mechanisms, it is one of the most spectacular and instructive stopping points on the route along the banks.

A remarkable engineering work inaugurated at the end of the 19th century to maintain maritime navigation towards Nantes, the Canal de la Martinière stretches its 15 kilometers parallel to the Loire estuary. Lined with period machinery, imposing locks, and natural bird reserves, it is today a prime spot for walking, fishing, and cycling on the Voie Verte. The site also hosts the contemporary artwork Misconceivable (the "soft boat") from the Estuaire trail.

This 19th-century church pays homage to the Anglo-Saxon hermit monk Vital, who lived in a cave in the rock beneath the church. Vital is the origin of the village of Saint-Viaud and gave it its name (Viaud = Vital).
