Austria's only lake thermal baths
Summer island with bathing lake
Follow the Trail

LakExperience with 100% bathing weather guarantee

From May to September, the sunniest summer in Austria and the Pannonian summer freshness beckon on "Summer Island". Then life shifts to the hotel's own 8-hectare bathing lake with crystal-clear water, the best water quality and a large sunbathing lawn. Many hours of sunshine and a seemingly finite horizon - these are the ingredients for a South Sea feeling that can only be found in one place in Austria.

Who doesn't dream of simply leaving everything behind to rediscover themselves on an exclusive island and enjoy refreshment all within reach?
