Does anyone know any campsites in Northern France (say 100 miles from Calais) that are open over Christmas with a decent quality indoor pool?

The nearer to Paris the better.   Have searched quite a few sites to no avail.

Understand this is a long shot, but often people have hidden gems they are prepared to share.

Many thanks in advance.
