PGA National Resort & Spa
Palm Beach Gardens, Florida
The Waters of the World pools are almost like aqueous islands, scattered among the grounds' lush grasses and palm trees. Two of the world's oldest and most coveted natural remedies infuse the waters: Dead Sea salt from Israel, which is used to detoxify the skin and quiet the mind, and Salies-de-Béarn salt from the Pyrenees Mountains, which can help with mood swings and water retention. The pools are the centerpiece of The Spa at PGA National Resort's internationally inspired <a href="http://www.pgaresort.com/spa/services">treatment menu</a>, which reads like a history of old-world spa therapies.
