Brittany is one of the easiest regions in France to spend a week in a motorhome: 117 free aires are mapped, the service points in most communes run mid-March to mid-November, and the distances between aires are short enough that a bad night costs you twenty minutes, not an evening.

What “free” actually means here

On a French aire, parking and services are priced separately. “Free” on a map refers to the parking. The borne, the service pillar, usually is not.

The Aire du Lavoir at Caulnes, in the eastern Côtes-d’Armor, is the standard shape. The Dinan Cap Frehel tourist office puts it plainly: “Stationnez gratuitement (24h maximum)”, free parking with a 24 hour limit. The coin-operated borne charges 2 euros to dump, 2 euros for 15 minutes of water, 2 euros for 3 hours of electricity. Bring 2 euro coins if you plan to use it.

Elven, inland in the Morbihan, is the generous end. The commune’s own page states: “Le stationnement est gratuit” and lists the water as free (“Recharge en eau (gratuit)”). Electricity is not currently available (“Pas d’électricité”), which is a change from older guides. Twenty-six spaces in total: 12 marked bays at the back, 14 open at the front. Verified on the mairie’s site on July 29, 2026.

The season sets almost everything

Mid-March to mid-November keeps showing up. Elven opens March 15 and closes November 15. Caulnes gives exactly the same dates for its borne. The reason is banal: the pipework would freeze, so the commune shuts the water off for the winter.

The parking often stays open when the borne is closed. If you are touring in November or February, that works, but you arrive with a full tank and empty cassettes. Do not plan a January trip around finding water at a village aire.

The two rules that actually matter

Wild camping and free overnighting on the Brittany coast are not as loosely regulated as an internet forum suggests.

  • Article R111-33 of the Code de l’urbanisme prohibits isolated camping on the seashore and in listed sites unless a derogation has been granted by the competent authority. That is a national rule, not a local one. With 117 free aires in a region this compact, the aire is almost always closer than the argument is worth.
  • Article R111-34 of the same code says a mayor’s camping ban is only enforceable against you once it has been made public at the mairie and signed at the usual access points. That is why the sign at the entrance is the one that counts: it is the mechanism, not a suggestion.

Building a week

The coast fills in July and August. Small aires near the well-known bays run full by midday. The interior does not.

One workable pattern:

  1. Head south to Elven, Saint-Jean-Brevelay or one of the inland Morbihan communes. You reach the Gulf of Morbihan in 20 minutes and you sleep for nothing.
  2. If you insist on the coast, plan the service stop inland. Town aires such as Saint-Meen-le-Grand run free water, electricity and waste all year, per the Ille-et-Vilaine tourist board.
  3. Fill water where you can. The bornes are busiest at weekends, and half of them are off in winter.

If this is your first time on French aires, what an aire is, the France rules and the Brittany region page with the named communes are the starting point. The sign at the entrance still wins over anything written here.
