Ungererbad is a huge, outdoor, park-like public facility that sports several pools, vast lawns and a 57-meter waterslide (see our photos). None of the pools are set up for competition lap swimming, no lane lines or bottom stripes, but they are long enough to swim across and accrue significant distance. Volleyball courts, "beaches" , a beer garden, and private nude areas are here as well. Ungererbad is open 9am to 6pm (May to September). Admission is a reasonable 3.40Euros. Closest hotel: Marriott (quarter-mile).
