All spa highlights
Celtic outdoor sauna village –
warmth meets ritual

Sauna worlds – variety in warmth
Gentle radiant heat or intense infusions? Your spa hotel at Lake Bostalsee offers five indoor saunas with varying temperatures and atmospheres. Panorama sauna with lake views, aromatic steam bath, bio-herbal sauna, ladies’ sauna, or steam bath – do you have a favourite? After your sauna session, a variety of refreshment options and relaxation areas invite you to unwind.
Infinity pool and natural bathing pond – swimming with a view
In the heated infinity pool, the water seems to merge seamlessly with Lake Bostalsee – your gaze stretches out into the distance. Or would you prefer to drift in the natural bathing pond – open year-round – with about 560m² of water surface? Don’t miss: the cosy retreats around the small beach area!
