South France eurocamp or similar without car

[Ramoaner]

For next summer. Will be getting train from Milan and want to stay around south of France (although open to other parts of France too). Won't have a car so preferably walking distance to a beach and a town. Would be happy to get occasional taxis.
Doesn't have to be eurocamp, anything similar is fine
There is are many of these sites out there so not sure where to start to hoping to get recommendations.
Kids aged 7+9. Would prefer to stay in lodge rather than tent. And would like a decent pool.

We’ve stayed here. In my experience of several eurocamps in various parts of France I’m not sure it’s really doable without a car.

Siblu La Carabasse or Club Farret in Vias Plage. You can get a 10 min taxi ride from Agde. Everything is in walking distance - beach, shops, restaurants, mini-golf, massive fun fair etc. You can rent bikes and cycle along the canal du Midi. Pool complex at la Carabasse is great.
