Try the local Municipal site at Camping des Roses, Les Sables d'Olonne, it's only 1/4 mile from the beach, has large pitches and is within a stones throw of this thriving & lively resort. Great restaurants on the front too. You'll need to book early as it soon gets full. It doesn't have a bar, club house, shop or takeaway, but all that is within 10 mins walk. Great beaches, all with bars/restaurants/takeaways - we've had 4 great holidays there with our 3 kids when they were little and as teenagers (16,17,18)
