- Swim through grottoes, take part in various wellness programs and give your soul a break in the South Seas ambience. Relaxing in the sulphur spring, where natural, unprocessed water, originating from a depth of 2,350 m, will ease rheumatic and arthritic pain. Power up with pure oxygen in the unique oxygen garden. The brine grotto offers a gentle but effective cure for coughs and sneezes, respiratory and skin disorders. Fountain of youth, bubble bath, steam and warm air chambers, as well as state-of-the-art tanning areas and the opportunity to play "floor" games add flair to this thermal paradise. On a warm summer day, when Europe's largest movable glass dome slides open, you can enjoy South Seas atmosphere under blue Bavarian skies.
