The Marienbad in Brandenburg an der Havel keeps the whole family in good shape and spirits, at prices like in the old days. Aquatic adventurers can reach record speeds in the tube slide, hold hands on the wide flume, hide in the cave or splash around in the warm baby pool. Confident swimmers, meanwhile, can make their way through the 50- and 25-metre pool or dare to jump from the 3-metre board. In the summer, the competition area turns into an open-air swimming pool with a beach volleyball court as the Marienbad retracts its convertible roof. Children’s parties, swimming courses for little mermaids and underwater photo shoots top off the excitement in this turquoise water world. If you feel peckish, head for the snack bars and the bistro and grab some chips or ice cream, while gourmets can enjoy fruit cocktails with fresh, warm traditional fare. Guests can treat themselves to a massage in the comfortable sauna area or on the bubble loungers with a view of palm trees.
