A Special Attraktion in the Outdoor Swimming Pool of Ergolding – The Wide Wave Slide with Plunge Pool. In the leisure pool Ergomar in Ergolding / Bavaria, a wide wave slide promises more fun splash. The special feature of the 3.00 metre wide and 12.00 metre long slide is its additional plunge pool. This enables the slide to be used independently from any swimming pool. This is an interesting alternative, particularly for smaller swimming pools where the existing pool would get diminished by the otherwise require safety exit area of a water slide.
