Canal de Garonne

Dug under Louis Philippe, formerly known as the "Canal latéral à la Garonne", the Canal de Garonne, an extension of the Canal du Midi, links the Mediterranean Sea to the Atlantic Ocean. 193 km long from Toulouse to Castets and Castillon, it has 53 locks, including 3 in Castets where the last one makes the canal accessible to navigation on the Garonne and vice versa. The banks lined with century-old plane trees, the towpath, the bridges and the locks make the site of Castets a heritage site of national interest.
