Perhaps more than any other part of the world, Central Europe has developed spa-going to a high art, or even a way of life. Many spas have been in vogue since the Middle Ages, or even Roman times; others came into fashion in the 19th century when resorts catering to royalty were built around bubbling mineral springs that offered specific cures for ailments ranging from arthritis to respiratory disorders. Still others have retooled to accommodate today’s spa-goer whose primary wellness needs are relaxation, pampering and stress reduction in a soothing, unruffled environment, coupled with tailored fitness programs, well-balanced nutrition and first class medical supervision. In the mountains or by the sea, in the forests or at many deluxe city hotels, delivering a rewarding spa experience is a Central European tradition. Consider this sampling.
