Cascade Water World. In the outstanding architectural site of CASCADE, swimming enthusiasts, relax-seeking swimmers and families will find a spacious water world with indoor and outdoor pools including wellness features such as adventure showers and much more. Children can splash and dive in pools designed for them, like the adventure and Kidspool. When not in the water, the little ones play in one of the colourful play corners for toddlers, or either in the playground in front of the restaurant or on the playground by the bathing pond. Youngsters and the young at heart will find the beach volleyball arena which, together with the huge natural bathing pond, the outdoor sauna and the adults-only sauna area, creates a chilled-out, relaxed atmosphere.
