The best road cycling routes around Bouaye

Charming little 11th-century chapel

Developed in the 18th century by the monks of the nearby abbey, the Canal de Buzay once connected the Acheneau to the Loire to drain and reclaim the surrounding marshes. Lined with a peaceful and shaded towpath, this straight waterway crosses the wild landscapes of the Pays de Retz, offering an ideal haven for cycle touring and wildlife observation. Today disconnected from the Loire at its lock, it remains a picturesque link in the local hydraulic heritage.

Located in the place called Champs-Neufs in Frossay, La Machinerie du canal housed two imposing steam engines capable of pumping up to 150,000 m³ of water per day to maintain the constant level of the Canal de la Martinière. Designed by the Fives-Lille company at the end of the 19th century, this impressive hydraulic system made it possible to compensate for evaporation and water leaks from the locks to ensure the passage of large commercial ships. Today restored and transformed into a museum space, the building preserves its original installations and bears witness to the industrial genius of the time.

The bridge of the Champs-Neufs lock (in Frossay) is distinguished by its riveted metal mesh railings and its wooden deck. Designed during the creation of the Canal de la Martinière (late 1880s / early 1890s), this structure is in the pure tradition of the wrought iron and riveted constructions popularized by the Eiffel workshops at that time. It is directly connected to the famous stone building of the Champs-Neufs machinery right next door, which housed the canal's water supply pumps. It is a very popular and particularly photogenic passage for all cyclists and hikers who tread the canal banks!

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.

The gate is also a central point for beautiful road or mountain bike climbs (sometimes hidden) as well as paths for all types of riding.
