Sense Spa, Rosewood Resort, San Miguel de Allende, Mexico
Located in the artists’ village of San Miguel, this sprawling spa draws inspiration from its south-of-the-border surroundings. The San Miguel Signature Mole treatment includes a massage and body scrub made from mole spices, while the Thermal Waters Wellness Journey starts out with a dip in the nearby natural thermal pools, followed by tea, breakfast, and a choice of services back at the spa (rosewoodsanmiguel.com).—Vanessa Lawrence

This painstakingly restored, grand-scale Victorian hotel—recently reopened after a 76-year hiatus—offers a menu of services that combine rituals from ancient cultures with modern technology. The Ko Bi Do Facial, for instance, uses age-old Japanese massage techniques to plump skin and tackle wrinkles; the Balinese Ritual of the Five Flowers Facial employs native Indonesian floral extracts like frangipani and lotus (renhotels.com).—V.L.
