Set your sights on a New Year’s getaway at this hideaway off the South China Sea. Tucked into a hillside, encircled by emerald foliage and dramatic chunks of charcoal-hued rock, the Six Senses Ninh Van Bay, in the seaside resort town of Nha Trang, Vietnam, is accessible only by boat. While some villas cling to the hillside, others sit at the water's edge -- and all have dedicated butler service 24/7. Incorporating traditional Vietnamese treatments, the highly touted spa excels at customized detox programs. Complimentary cooking classes seal the deal.
