No need to use your car, whether you are going to town or to the beach!
You can reach the town and its shops via a pedestrian path in 15 minutes' walk. There is also a bus service 150m from the campsite which serves the town centre as well as the supermarkets. The largest beach in Concarneau, "sables blancs", is situated 150m from the campsite. Once again, no need for a car!
