Galaxy Erding is the water slide complex at Therme Erding, a massive thermal spa in the Bavarian town of Erding, about 30 minutes northeast of Munich, Germany. The Galaxy section opened on March 31, 2007, adding a dedicated slide park to the thermal baths that had opened at the site in 1999, quickly making it one of the largest indoor water slide parks in Europe.
Housed beneath a domed roof that can be partially opened in summer, Galaxy Erding now features 28 water slides stretching roughly 2,850 meters combined, built with attractions supplied by German manufacturer Wiegand.Waterrides. Slides are organized into three difficulty tiers, letting families and thrill-seekers alike choose an experience that matches their nerve.

The Ride Experience
Galaxy Erding’s slide lineup ranges from gentle family rides to genuine adrenaline. The Magic Eye tube slide is the headline attraction, running about 365 meters through darkness and light effects and marketed by the park as the longest of its kind in the world. For steeper thrills, riders can try the Kamikaze, a roughly 34-meter chute with a drop of about 60 degrees, or the tire-raft Big Wave, which includes an outdoor water-halfpipe section.
Other rides, like the Black Mamba and the multi-slide Space Glider, add themed lighting and uphill sections to keep the ride from being a straight drop. Some slides also offer scheduled virtual-reality sessions, an unusual feature for a water park, letting riders wear a headset synced to the twists and turns of the slide.
Part of Europe’s Largest Thermal Spa
Galaxy sits within Therme Erding, a thermal bathing complex that traces back to 1983, when an oil-drilling operation near Erding struck sulfurous thermal water instead of oil. The broader Therme Erding complex opened in October 1999, and the Galaxy slide section was added in 2007 to give the resort a dedicated water park alongside its saunas and thermal pools.
The domed Galaxy hall rises about 25 meters and can be opened in warmer months, blending an indoor park’s reliability with an outdoor feel. Therme Erding as a whole draws an estimated 4,000 visitors a day, making Galaxy one of the busiest indoor water slide destinations in Europe.
