The Best Destination Spas in the US & Around the World: 2024 Readers’ Choice Awards

"On the northwest coast of Sardinia, less than a mile from Isola Rossa, a picturesque fishing village on the Gulf of Asinara, you’ll find the Hotel Marinedda Thalasso. The spa, L’Elicriso (the everlasting flower, in English) is an airy 27,000 square foot wellness oasis that specializes in thalassotherapy—from the Greek word thalassa, meaning "sea,” it’s the use of seawater for its therapeutic properties. Mentioned as far back as 480 B.C. in the works of Euripides and Hippocrates, this treatment method was en vogue in ancient times, and is just as effective for washing away the stressors of modern life. The spa offers four heated seawater pools, two saunas, a hammam overlooking the Marinedda Bay, and an extensive variety of thalasso programs, massages, and beauty treatments."
