Being unfamiliar with the pool scene in Germany I didn't know what to expect here, and I made…read moreseveral mistakes. Note: wear a swimsuit for lap swim, no swimsuit for pretty much everything else.
Downstairs there's an all-shallow outdoor pool and two indoor pools. One is for kids and is all shallow, the other is the "sport" pool and has a deep end. The sport pool also has a 1m and 3m diving board. I think you have to ask the lifeguard to use the diving boards.
Upstairs there's lots of sitting areas to chill (inside and out), a place to get food and drinks, four different types of sauna (two dry hot, one wet, one aromatherapy), and an outdoor pool that's heated and has bubbles and submerged chaise lounges. These are all naked. Some of the sitting areas have heat lamps. Everyone had at least one towel, most people had towel, bathrobe, even a blanket. Some people brought books to read under sunlamps.
When you arrive, tell the attendant at the desk if you just want to swim or if you want to go to the sauna (upstairs) too. The prices/times are on the website. Once you decide, you get a plastic bracelet and a plastic card. The card is for your locker. Inside the locker is a black box. Insert the card there and shut the door, hard, once all your stuff is inside. Then take the blue numbered lanyard that pops off the locker door. It has a buckle so you can tie it to your wrist, ankle, whatever.
What to bring: swimsuit, goggles, cap, towel for drying off, towel for sitting on, bathrobe, SHOWER SHOES, shampoo/soap, something to read if you like, water bottle, cash to buy food/drinks, large bag big/waterproof enough for all your wet stuff when you head home.
The showers didn't provide soap and while the water pressure is good the stream isn't as heavy as us long haired women need. There are several hair dryers available.
Overall this was a very replenishing and relaxing cultural experience. I plan on going as many nights as possible.
