Les Castles France

Im currently planning to try and go to a les castle site this summer with my wife and kids aged 13 and 5.

Im new to caravaning and never been abroad towing does anyone recomend any of the sites for familys and younger kids.

Im looking at Sequoia Parc,Domaine des forges and Parc de Fierbois they all look good for familys but its always good to hear from someone who has been there in person rather than reading reviews on their own site.

Im also not sure what the best crossing to take either Ill be traveling down from Newark on Trent.

Thanks
