The Original FX Mayr clinic is on the shores of the lake Worthersee at Dellach.
It has been called (by Tatler) the most radical modern health spa in the world. The Daily Mail gave it this ecstatic review.
It is not a spa at all in the English sense but a medical centre that has pioneered the role of an alkaline diet combined with holistic approaches to good health and well being usually for a week or more. It is a place to get well surrounded by the forests, the second oldest golf course in Austria and the lake itself.
