Best Spa Hotels in New York

Aman's 25,000-square-foot, three-story spa is the most serious in the city: a 65-foot pool flanked by firepits and daybeds, banya and hammam suites, and treatments that run half a day. Even day access is coveted. For a pure spa staycation, nothing in New York compares.

The Peninsula stacks its spa on the building's top floors, so massages and the glass-walled pool come with Fifth Avenue skyline views. The thermal suite earns the afternoon; the rooftop bar afterward closes the argument. A complete spa day without leaving Midtown.

Spa Nalai at the Park Hyatt keeps the wellness floor 25 stories up: a three-lane pool with Carnegie Hall recordings playing underwater, steam and sauna suites, and treatment rooms above 57th Street's roofline. The most musical swim in Manhattan.

The Ritz-Carlton pairs its park-view rooms with an intimate spa suite program — book a treatment, then take the recovery walk in Central Park across the street. Small, quiet, and personal where the big spa floors are busy.

The Mandarin's spa floats 35 floors over Columbus Circle with an amethyst-crystal steam room, a vitality pool facing the skyline, and the group's famous Time Rituals treatments. Swim laps looking down the length of Central Park, then take tea in the lobby lounge.

Shibui Spa sits beneath the Greenwich in candlelight: a swimming pool under the timbers of a 250-year-old Japanese farmhouse, bamboo soaking tubs, and shiatsu on tatami. It takes a handful of guests at a time, which is the point. Tribeca's best-kept ritual.

The downtown Four Seasons hides one of Manhattan's best hotel wellness floors: a 75-foot skylit lap pool, steam and treatment suites, and enough calm to forget the Financial District is outside. The spa stay for swimmers.
