Spa at the Bellagio

One of the older spas on the Strip, this 65,000-square-footer still holds its own. Day passes gain you access to the eucalyptus steam room, redwood sauna, hot tubs and cold plunge, but glance at the services list and you’ll find plenty of temptations for relaxation or reinvigoration. Get a customized workout in the fitness center or join a group barre or spin session. Then head outdoors for a poolside massage or perhaps try an aquatic therapy like a stretching session or couples massage class in the 94-degree spa pool.
