Billing itself as the biggest water park in Central Europe, Aquapalace is the place to go for all your wet and wild fun. The massive complex includes three different indoor water adventures with slides, artificial waves and whirlpools; two aquariums to spot sea life and coral up close; 14 different heating rooms as part of their Sauna World plus the opportunity to book facials and massages. There’s lots of space and activities for children, restaurants and food stands and a hotel on site if one day is just not enough.
