Buchinger Wilhelmi at Lake Constance

A breath of fresh air

Buchinger Wilhelmi Lake Constance clinic is situated high above Lake Constance with breathtaking views over the forest-lined shores of the lake and Mainau Island to the snow-topped peaks of the Alps. Here, in this beautiful, almost Mediterranean landscape, Dr. Otto Buchinger found the ideal setting for his fasting clinic – close to nature, spacious and inspiring.
