Cancun has 30+ spa resorts, so couples in search of a treatment-whether solo or simultaneous-have plenty of options. Beyond typical spa services, there are also unique treatments reflecting local culture. Temazcal, for example, is a pre-HIspanic ritual intended to cleanse the body and mind through deep relaxation in a shaman-led experience that takes place in a sweat lodge or sweat bath. If that's too intense for your taste, ask about other Mayan-inspired spa treatments. Options might include a massage with gold and jade, anise seed, brown sugar, and honey, or herb-infused essential oils.
