Aqua Dome in Längenfeld is more than just a spa—it’s an alpine oasis where you can float in warm outdoor pools, each heated to 34–36 °C, with a backdrop of soaring 3,000 m mountain peaks. The spa features 12 pools, including futuristic bowl-shaped thermal basins with light and sound effects, alongside 14 themed saunas like herbal, earth, and canyon saunas. Families will love the separate Alpen-Arche-Noah water world, complete with slides, a fun pirate-ship zone, and kid-friendly pools.
