Camping Hautes Coutures used to be (still is?) associated with Brittany Ferries. We have used this site frequently in the past and found that they stayed open until the last ferry had arrived in port in the late evening. A good site for an overnight halt, or longer. As Val A has suggested Camping Le Pommiers, which is much nearer the port, is a bit tired. We stayed there in Mar homeward bound from Spain and whilst it was OK for an overnighter then, I would hesitate to use it in high season.
