Azur is a small village located a few kilometres north of Soustons and next to the lake (Étang de Soustons). This 11.3 km long, completely flat route (pictured left) starts in Azur itself, at the junction of rue Gaston Nougaro and the D-378, where the Espace François Mitterrand is located (pictured right).
It runs mostly on country roads through the pines, but also includes some asphalt roads and a cycle path.
The entire route is indicated by markers that show the way to follow at the many forks along the way, so you must be very attentive to these indications.
