Parc Naturel Régional de Brière – La Grande Brière
Just 20 kilometres north of Saint-Nazaire, the Grande Brière is the second-largest peat marsh in France — a haunting, beautiful labyrinth of reed beds, black canals and thatched-cottage villages that feels centuries away from the industrial waterfront. Hire a flat-bottomed chaland boat and pole your way through a landscape that has barely changed since the Middle Ages.
Getting out on the water
The village of Saint-Joachim is the classic entry point: from the port de Bréca, you can hire a traditional chaland with a boatman guide (bateleur) who poles you silently through the narrow channels while pointing out grey herons, marsh harriers and the occasional otter slide on the bank. The experience is meditative and genuinely magical.
Independent canoe and kayak hire is also available at several points around the park perimeter. The marked water trail from Bréca to the Île de Fédrun — a low island village of thatched houses — takes about 90 minutes each way at a relaxed pace.
On dry land in the Brière
The Île de Fédrun is worth exploring on foot: its circular road is lined with traditional chaumières (thatched cottages), and the Maison de la Mariée museum inside one of them tells the story of Brière wedding traditions with genuine charm. The village boulangerie sells excellent galettes.
Birdwatchers should visit at dawn in spring (April–May) when the reed beds ring with the booming call of the bittern, a rare and elusive bird that breeds here in good numbers. The park's flat cycling paths are also excellent for a half-day loop.
