This past weekend, I celebrated my birthday at Gurney's Inn Resort Spa & Conference Center (Montauk, NY). As one of the country's only thalassotherapy spas, it offers a host of nourishing sea water treatments. While there, I experienced the Marine Kur Therapy ($265, 90 minutes), which involved a gentle exfoliation, a seawater hydrotherapy massage, a mineral-rich seaweed body wrap, and more. Spa-goers who want to take advantage of all that Gurney's has to offer won't want to miss the resort's upcoming Spring Wellness Retreat (starting at $350 per person). Scheduled for April 13 to 15, the weekend of holistic renewal features various speakers, such as Dan Freyda, founder of Spa Technologies; Karen Ranzi, an author, raw living foods consultant, and speech pathologist; Leonard Fazio, DDS, a holistic dentist; and more. The program includes two nights of oceanview accommodations, healthy breakfast and dinner buffets, wellness workshops, a psychic fair, and use of the Sea Water Spa facilies. While my birthday weekend might have been more hedonistic than holistic, I still left Gurney's feeling rested and restored.
