Even if you’re not staying in this huge holiday park, you can use the sports facilities at Center Parcs and, even better, go for a swim at Aqua Mundo. This large swimming pool is full of waterslides, aquatic plants and clean water that is always kept at tropical temperatures. It's also a handy alternative to the North Sea, which is usually too cold for swimmers most of the year. And if the heated swimming pool isn't hot enough for you, a sauna is available. Center Parcs also offers a wide range of sports and activities including squash, tennis, volleyball, mini-golf and bowling.
