Great Jones Spa

It’s serene, simple, and straightforward, sans the intimidation factor you might find elsewhere. They have the usual treatments—facials, massages, manis, pedis—and then there’s the water spa, built around a 3-story indoor waterfall. A 3-hour pass for $55 gets you into the hot whirlpool, eucalyptus-infused steam room, dry sauna, and cold plunge pool. Weekends and weeknights are especially busy. If you can, go on a weekday. It’s nicer when you don’t have 20 people in a pool with you.
