If you want a bit of pampering, cleanse your body and soul at Temazcalli, a spa that claims its treatments combine the energy of wood, fire, rock, and medicinal herbs. They still use the pre-Columbian techniques, so it's a true cultural experience. Choose a private scented steam (less than $10 each for two people) or a ritualistic group cleansing; the latter involves chants and prayers. Or opt for a good old-fashioned massage with scented oils.
