This is by far my favorite pool in the Ktown area. Not only is it nicely laid out with lots of water features and fun for the kids...it's WARM! Like, really warm. Almost bathwater warm. The air temperature is kept at a nice temperature also, so you aren't freezing while you lounge on a pool chair and the kids take run after run down the awesome water slides.
This pool has two excellent water slides. One is the "black hole" and it's completely pitch black at parts, which is pretty exciting for us big kids too. The other is called the "Turbo-Reifenrutsche" which is a high speed inner tube slide. Both of the slides are also kept at a nice warm temperature. You will need to haul the inner tubes up a few flights of stairs, but they have smaller, lighter ones for the kids.
The baby pool is also nice and warm for the littlest guests and they will enjoy all the bright colors and water features. This pool is separate from the larger pools, so the kids can feel comfortable without the bigger kids splashing about.
Besides the main swimming area and the water slides, there is also a lazy river, whirlpool, and outdoor pool. While we were there, the main pool turned into a wave pool, once every hour. The kids really loved floating amongst the waves and getting splashed when they broke by the pool shore. There is plenty of seating on both the first and second level. In another section of the pool is a sport pool with diving boards.
As far as pricing, they have a family day card for 19.90 Euros. This pays for the entire day access for 2 parents and unlimited kids, making this an awesome option if you've got a large family. They also offer reasonably priced food options such as hamburgers, sausages, and other German fare plus coffee and a selection of drinks or you can bring in your own. You will get a chip when you pay at the entrance which you use to open your locker. The chip will then remain in the wristband and you will use this to purchase any food or beverages, so you can leave your wallet locked up. Parking is easy and there are tons of large spaces.
