Naturfreibad Haunstetten, Natural water park in Haunstetten, Germany

Naturfreibad Haunstetten is an artificial bathing lake in southern Augsburg with a water surface of 10,500 square metres and a maximum depth of seven metres. The lake is divided by an island reached by two bridges; the larger eastern part once held starting blocks for a 50-metre course, while the western part had a diving board and a slide. A tower on the south shore now serves the water rescue service.

On 21 July 1958, the Haunstetten town council decided to build a natural swimming pool; the first spade was turned at Roggenstraße by mayor Karl Rieger and Captain Boylan of the US Army engineering unit, whose bulldozer removed the topsoil from 14,000 m². The pool opened on 3 July 1960 before 13,751 visitors. The city ran it until 1972, when Augsburg took over after incorporation; in June 2010 volunteers and donors reopened it after safety defects, and the Naturfreibad Haunstetten association was founded on 25 June 2010.

The facility takes its name from the Haunstetten district and serves as a gathering place where locals spend warm months swimming and relaxing together. Families and friends return here year after year, making it part of the summer routine for many who live nearby.

The facility is best visited during daylight hours when sun warms the water and grass areas. There is plenty of space to lie and sit, but on hot weekends it can become crowded, so arriving earlier in the day works well.

The water is kept natural and chlorine-free through a monthly quality testing program to maintain high safety standards. This approach makes swimming here more enjoyable for many people compared to traditional chlorinated pools.
