Welcome to the Brière Regional Natural Park!
With over 122,000 acres of peaty land, canals and endless horizons, the Brière is one of the largest wetlands in France. Saint-Nazaire does not lie exactly in the heart of the Brière but swamps and canals are part of the town’s natural heritage in its Northeastern corner. Both marshland and bocage cover nearly half of the municipal area.



France’s second largest marshland
How can we describe the Brière? It’s France’s second biggest marshland, containing a wide variety of natural ecosystems, home to 900 different plants and thousands of birds including bluethroats, herons, egrets and ducks… Yes, all this and so much more!
But also… a haven of calm and silence! Just a soft breeze rustling the reeds.
These exceptional man-made natural landscapes are an invitation to come and enjoy the stillness that the Brière offers.
