While luxury spas are aplenty, wellness spas have a different take -- alongside a steady menu of massages and facial treatments, spagoers can consult with physicians, lose weight, quit smoking, sample "detoxifying" body treatments, and enjoy specialized meal plans -- often set in some of the most pristine places in the world. Here are a few top spas that aim to heal body and mind.
