Bad Ragaz

From the outside, this massive Swiss chateau looks pretty storybook, but inside, there's serious healing going on. The in-house doctors and therapists customize every wellness program—points of focus include everything from basic stress relief to careful post-op care—to revolve around taking in its prized, anti-inflammatory thermal spring waters—by way of pools, steam rooms, and saunas. They're pumped in from an ancient gorge and are said to ease everything from arthritis pain to eczema.
