Natural Hot Springs in San Miguel, San Miguel de Allende
Concierge.com's insider take:
Steam from natural hot springs rises above the countryside along the road to Dolores Hidalgo in an area dubbed Hot Springs Way (signs along the highway mark the various spots). La Gruta is one of the largest springs, with a man-made cave and waterfall, plus thermal pools, a lounging area, massage services, and a small restaurant. Locals tend to hang around for the day, especially on weekends, but visitors can do the whole circuit in an hour or two. Taboada, another spring, has a large swimming pool for kids; waterslides draw families to Xote.—Maribeth Mellin
