SpaTerre at Kona Kai Resort and Spa is an upscale full-service spa set within 11 acres of tropical landscaping on Shelter Island in San Diego Bay. Drawing inspiration from Indonesian, Fijian, and Thai healing traditions, the spa offers massages, facials, and body treatments using Pure Fiji products, performed across six treatment rooms including a couples suite with a soaking tub. Guests can unwind in the eucalyptus steam room, enjoy heated massage tables, and relax in the dedicated lounge. Private yoga and meditation sessions complement the therapeutic menu, and an adults-only pool enhances the resort experience. Both resort guests and the public are welcome at this tranquil waterfront sanctuary.
