Architectural Grandeur & The Retractable Glass Sky-Dome

Located just 15 minutes from Munich Airport, Therme Erding holds the undisputed title of the largest thermal bath complex on Earth. Its engineering centerpiece is a monumental semi-spherical glass dome spanning 56 meters in diameter that physically glides open during summer months, transitioning an indoor paradise into an open-air Mediterranean oasis in under eight minutes.

The waters feeding Therme Erding originate from the Ardeo source, tapped at a subterranean depth of 2,350 meters. Enriched with sulfur, fluoride, and therapeutic minerals at a natural ejection temperature of 65°C, the water is carefully cooled across varying zones ranging from 34°C soothing lagoons to 40°C high-intensity hot springs.

Galaxy Erding: High-Velocity Waterslide Engineering

Galaxy Erding represents the zenith of indoor slide development in Europe, segmented into three distinct adrenaline categories:

Family Level: Gentle wide multi-lane slides, interactive kiddie splashes, and sensory light-tunnel descents.
Action Level: Europe's longest tube slide, the "Magic Eye" spanning 365 continuous meters, along with double-wave racer tubes.
X-Treme Level: The "X-treme Faser" reaching speeds of 72 km/h, and the "Kamikaze" slide with a sheer 60-degree free-fall drop.
