The venerable hotel chain pitches its first tent with these 15 luxe shelters scattered on 200 rugged acres along the Thai-Burmese border. The canvas-covered, 600-square-foot accommodations are ultra-private and have generous decks, pillowtop beds, outdoor rain showers, and copper bathtubs. True to the camping spirit, guests can opt for communal dining. The most memorable moments here are spent with the six elephants, at river bathing sessions and on treks through the bamboo bush. The camp's mahouts lead guests through a day's program that turns this five-star resort into a unique training experience. The aptly named Mahout Recovery massage offered at the two spa tents works wonders on achy thigh muscles.
