Staying in a hotel with a water park provides lots of fun for you and your family. Those staying at the hotel can generally use the hotel's on-site water park or a water park located close by. Access to the water park is free at some properties and others may charge a small fee. Pack your swimsuits and enjoy a fun-filled getaway to Saint-Hilaire-de-Riez: splash pads, waterfalls, and waterslides await.
