Grand Hotel Excelsior Vittoria Piazza Tasso, 34 80067 Sorrento, Italy

Created in a converted 19th-century greenhouse adjoining the hotel’s swimming pool, the sunny Boutique Spa La Serra sits amid olive and orange trees. The 2,400 square-foot space's design pays homage to Feng Shui healing traditions, and each spa suite has its own Jacuzzi bath tub, dressing room and private garden. Treatments use products from top lines like Organic Pharmacy; choose from individual services or tailored programs designed to relax, detox, treat cellulite or fight signs of aging.
