This is the area that corresponds to the alluvial valley of the Garonne. Bordered by the Garonne to the east and the Bordeaux-Toulouse railway line to the west, it extends over nearly 2000 ha over the municipalities of Cadaujac, Saint-Médard-d'Eyrans, Ayguemorte-les-Graves, Isle -Saint-Georges, Beautiran and Castres-Gironde.
We invite you to discover it thanks to two hiking trails: the trails of Ayguemorte-les-Graves and Saint-Médard-d'Eyrans.
Maps of the hiking trails are available at the Tourist Office or can be downloaded from our website.
