Saintes-Maries is situated in the plain of the Camargue, 12 m.
The Rhne, the source of which is in Mont St Gothard, in Switzerland, enters France by the narrow defile of LEcluse, and has a somewhat meandering course, first flowing south, then north-west, and then west as far as Lyons, whence it runs straight south till it reaches the Mediterranean, into which it discharges itself by two principal branches, which form the delta or island of the Camargue.
There is also a good annual world music festival in Arles, near Marseille and the Camargue, in mid-July.
