H2O Hotel Therme Resort

Bad Waltersdorf

The H2O Children's Thermal Bath offers over 1,000 m2 of in- and outdoor water areas and a firework of water attractions. The Double-Tube Slide (twice the normal width) and the “Blackhole Speedy” provide young and old with fantastic sliding fun. An impressively huge range of adventures await you!

Loads of water & thermal fun

Of course, water slides must not be missing in any children's and family thermal bath. At the H2O children's thermal bath in the district of Sebersdorf in Bad Waltersdorf, several slides offer endless water fun.

Racing slide fun is guaranteed: The mega-wide double tube slide “The Blue Lightning” guarantees plenty of action with its speed. The “Speedy” also delights with fast descents and promises an exciting experience for all thrill-seekers. The tiniest bathers can let off steam in the baby pool and at the clown pool.

A different kind of water fun is promised during the summer months with the Waterballs, also known as Aqua Zorbing. In this cool water attraction, you climb into an inflatable plastic ball and walk on water with a bit of skill. Great fun, even for spectators at the poolside.

For many girls (but also boys), a mermaid is part of the proper water experience. Mermaiding, swimming with a mermaid tail, is also possible at the H2O children's thermal bath. Glide elegantly through the pools, swim like a mermaid, and experience what life feels like as a mermaid, all this is waiting to be discovered!

If you prefer a more relaxed pace, you are in the right place in one of the numerous pools. The star pool, for example, invites you to daydream. From here, you have a good overview of the entire thermal bath. The current of the lazy river gently carries guests in circles or always towards the gemstone whirlpool. And the brave dive into the waves of the wave pool with Acapulco beach and let themselves drift. The tiniest guests feel right at home in the HopiHo water play garden, named after the squeaky yellow, cheerful mascot of the H2O Hotel-Therme-Resort.

By the way: Parents enjoy relaxation and tranquility in the sauna world alongside the pleasantly warm thermal water. Seven saunas, such as the Lappensauna or Azur-Tepidarium, and the 5,000 square meters sauna garden provide plenty of space to breathe, sweat, and simply enjoy the peace.
