This aire is no longer free but it is well worth the 7euros it now costs. It now has a barrier which even accepted my travel card (a first in France so far) and issues you with a bar code. There are 27 bays. The price includes water, waste disposal and electricity (as long as you can beat the man with a mile long cable who hogs it for a whole day). The aire is beside a river/canal with lots of lovely walks, outdoor gym equipment, an amazing arboretum and free dog-poo bags!!!!! It's a lovely clean aire with very big spaces (avoid the one by the skateboard park). A van calls in the morning selling baguettes. Really recommend this aire if you're in the area.
