Where to park your RV in Carnac: official options
Two locations, no unpleasant surprises
In Carnac, there are two official sites for motorhomes: the Square Illertissen area in Carnac-Ville and the motorhome zone at the Kérabus parking lot, on the road to Auray. These are the only legal options for overnight parking in a motorhome within the municipality. Elsewhere in town, extended parking of a motorhome is subject to the general rules of the Highway Code and may be subject to restrictive municipal ordinances.
To plan your visit, check the latest information directly on ot-carnac.fr before you go. Prices and admission policies may vary from season to season.

The Square Illertissen Motorhome Park (Carnac-Ville): Everything You Need to Know
To park your motorhome in Carnac, the service area is located at Square Illertissen on Rue Saint-Cornély, 500 meters from the stone rows and 1.5 kilometers from the beaches.
Waste disposal and electrical hookups available for €2.50.
The Kérabus Parking Lot: Daytime Parking and RV Area
If you want to spend the night near the megaliths, the Kérabus parking lot is the place to go.
Open 24 hours a day, it is located just a stone’s throw from the Alignements du Ménec and is accessible from the Auray Road (Route du Purgatoire).
During the high season, from June 15 to September 15, parking costs €5 per 24 hours.
Good to know: In Carnac and the surrounding area, daytime parking (9 a.m.–9 p.m.) is permitted in standard parking lots, except in sensitive areas (Saint-Colomban, Anse du Pô).
What every RV traveler needs to know before arriving in Carnac
Gray and black water disposal: Dumping stations are available at both locations, Square Illertissen (Rue St. Cornély) and the Kérabus rest area (Impasse des Alouettes), which has a dedicated gray and black water disposal station. Please have €2.50 ready in cash or by card.
Drinking water: A water station is available in Kérabus.
Electricity: 10A power available at the Rue Saint-Cornély site (40 spaces). Connection available 24/7 at Kérabus.

What you need to know: Where can you park your RV in Carnac?
Legal or illegal, the line is clear
In Carnac, overnight parking of a motorhome in a public parking lot is legal, just like any other vehicle. What the Highway Code prohibits is camping, that is, setting up tables, chairs, awnings, or any outdoor equipment outside of designated areas.
The distinction is simple: sleeping in your vehicle in a public parking lot is considered parking. Setting up your gear and making yourself at home as if you were at a campsite is considered wild camping.
What the regulations say in Brittany:
The Coastal Law imposes additional restrictions on protected coastal areas. In Brittany, coastal areas, dunes, and designated natural areas are subject to strict regulations that prohibit the establishment of any campgrounds outside authorized zones. Carnac, a seaside resort in Morbihan, is directly affected by these provisions.
What the Carnac City Hall says:
Local ordinances may restrict or regulate RV parking in certain areas of the municipality. To find out which areas are off-limits and what rules are in effect during your stay, visit carnac.fr or contact the town hall directly. We do not list any fine amounts here, as this information must be verified through official sources.
Things to keep in mind before you go:
- Overnight parking in a camper van in a public parking lot = legal (Highway Code)
- Camping (outdoor setup) outside designated areas = prohibited
- Protected coastal areas in Brittany = additional restrictions (Coastal Act)
- In Carnac: use the official areas (Square Illertissen, Kérabus) or a campground to avoid any risk
- Carnac municipal ordinances: Please check mairie-carnac.fr before your arrival
The simplest advice is to park at the official sites designated by the tourist office, or to reserve a spot at a campground that welcomes RVs. This is the only way to be sure you won’t have any unpleasant surprises when you wake up.
Municipal rest area or campground with RV sites?
Two approaches, two profiles
Whether you choose a municipal rest area or a motorhome site at a campground depends on your travel style and how long you plan to stay in Carnac.
The municipal campground is ideal for self-sufficient RV travelers who stay for 1 or 2 nights, rely on their own resources, and prefer complete freedom of movement. It’s the economical choice for a short stopover.
Camping with a motorhome site is ideal for couples or families staying 3 nights or more who appreciate the restrooms, Wi-Fi, and the option to reserve their spot in advance.
During peak season in Carnac, making a reservation ensures you won’t arrive only to find there’s no room.
