Best of Boston

2015 Best Day Spa

The Mandarin Oriental

This massive spa offers a steam room with star-like lights, a dimly lit “vitality pool,” and services that truly transport. For an indulgent experience, try “The Retreat,” a six-hour journey including a private yoga or Pilates session, foot therapy, a facial, lunch in the spa’s café, and a full-body exfoliation and massage.
