At the heart of Loire Atlantique, the Guérande salt marshes cover 1,400 hectares where geometric shapes meld with pastel shades to create astonishing landscapes. Take a walk, a bike ride or a horse-drawn coach ride through the marshes, and discover the techniques used for gathering salt. These go back to the 9th century and are mainly based around regulating water levels in a sequence of basins so that the water evaporates and the salt crystallizes.
In this way, without using any machines or chemicals, the paludiers gather the "white gold", a delicacy for gourmet diners: fleur de sel. To brush up on your knowledge of salt and the lifestyle of the paludiers throughout history, you can visit the Marais Salants museum in Batz-sur-Mer, with its fun and fascinating exhibition.
