Excellent bike ride, for those who are used to it, as well as for beginners. I recommend it, because there is a section of woods, a section of road and a trail.

A small town lying along the Gironde estuary, between Barzan and Mortagne-sur-Gironde, it is above all famous for its fishing port, which was the "French capital of caviar" for much of the 20th century: in the mid-1950s, between three and five tonnes of this luxury commodity were still being produced, exported worldwide. However, sturgeon fishing was banned in 1982 to protect the species; now, "Gironde caviar" is obtained from aquaculture farms: nearly twelve tonnes of caviar are produced each year in the region. At the gateway to the great marshes on the north bank of the Gironde, it is now a tourist and agricultural town.
