One of the most beautiful beach destinations in the world, Costa Rica has more of a laid-back, surfer vibe than some more posh Caribbean destinations, like St. Barts and Anguilla. But if you're seeking a touch of luxury while there, these hotel spas offer world-class services in incredible facilities. Whether you're looking for a rustic retreat or a sleek, state-of-the-art spot, these spas are hard to beat. The upper-middle-range Asclepios bills itself as a wellness center rather than a hotel, though it successfully incorporates elements of both. The full spa includes a dry sauna, hammam, hydrotherapy treatments, and much more.
