2021 Best Day Spa

Mandarin Oriental, Boston

Slippers on, phone off, Zen ahead: Simply arriving at Boston’s grand dame of day spas is a treat for the soul. And once you’re checked in, your massage, body scrub, or facial is just the beginning: The facility’s peaceful thermal amenities, including a warm plunge pool and quartz-crystal steam room, are more than worth carving out a little extra time for. Still craving a few more hours (ahem, days) of pampering? Settle in for one of the hotel’s new three- or five-night wellness retreats with luxuries such as butlered bath service, yoga, daily organic meals, and, of course, plenty of spa time.
