Opened in November 2007, Terme Milano boasts over 30 different scrubs, muds, creams and steam experiences, all housed in (or around) a sprawling Art Deco complex built in 1908 and formerly owned by the city’s public transport system. Armed with nothing but your swimming costume (an abundance of towels, robes and slippers are on hand), follow the earth, air, water or fire circuits, the latter complete with contemporary glass cube fireplace. Or pick and choose among the various chromotherapy tubs, pressure waterfalls or bio-saunas. Outdoors, 15th-century city walls ring the Spanish Garden’s teak decks and vast hydromassage pools, surprisingly effective in stilling the surrounding urban noise. Those hitting a sugar low can dive into the yogurt, juices and fruit arranged in pyramids on a central table. For an extra fee, continue the detox with a massaggio linfodrenaggio. There are no time constraints on entry to the Terme; if you plan to dig in for the day, check out their Day Spa Anti-stress package, which includes a free 50-minute massage.
