Fabulous and very friendly sauna complex about 35 minutes south Bonn. We went on a Monday and it was clear that this is a favourite place for locals to meet up, relax, sauna and swim, then out into the gardens for some sun. Even on a sunny March day, the garden had lots of us enjoying the late winter sun. The saunas are large and the Aufgüsse (sauna ceremonies with a sauna Meister who gets the heat up and 'pours' it over you by using a towel) were very well attended (over 40 people in the first one of the day) and exceptionally good. Remember that in Germany, saunas are without clothing. You must sit on a towel, but you may not wear swimming trunks, costumes or any other clothing. You will see other naked people and they will see you. Nobody bats an eyelid, nobody gawks or stares, and all ages and body shapes and sizes are represented. Probably equally 50/50 men and women. The restaurant upstairs was wonderful! Huge selection of food from salads and soups, to more substantial local delicacies. This is the only part of the complex that you need wear something; most people wear a dressing gown. In some saunas, you wear a chip wristband and everything you buy, such as drinks or food or massages, gets charged to that and you settle up on departure. Here you get a little slip of paper and everything that you buy during the day is written on it, and again, you settle up on departure. They warn you to keep this in your locked locker till you actually need it, as there's a hefty €80 charge if you mislay it. We found the staff were very professional and helpful, and this sauna is much more reasonably priced than many - a whole day is just €31. Bargain!
