The jet pool at Grand Velas

The Riviera Maya boasts more destination spas per square mile—plus a better beach—than anywhere else in Mexico. And nestled among the meandering lagoons of Mayakoba, ensconced on its own miniature island, the 17,000-square-foot Sense Spa at Rosewood (rooms from $590; massage from $145) was the region’s first luxury game-changer (with authentic wood-fired stone temazcal), surpassed only by its Asian-inspired next-door neighbor,Banyan Tree (rooms from $565; massage from $160), whose therapists train for 300 hours at the company’s flagship in Phuket, Thailand.

On the boutique tip of the scale, Orient-Express’ 65-room, white-walled, palapa-topped Maroma (rooms from $765; massage from $125) has created an utterly chic, tropical utopia at its Kinan Spa. While on the other, more colossal scale of things, the all-inclusive and truly exquisite Grand Velas (rooms from $570; massage from $178, gratuity included) delivers a surprisingly intimate escape at its 89,000-square-foot, jungle-wrapped sanctuary, which revolves around a must-see-it-to-believe-it vitality pool and temperature-controlled chambers for indulging in therapeutic clay, shaved ice or fragrant steam. And the 8,600-square-foot spa at the 88-room Ceiba del Mar (à la carte from $219; all-inclusive from $303; massage from $100) even offers an all-inclusive spa deal that allows as many treatments as you can possibly squeeze into your sangria-soaked itinerary.

Rates given are for a 50- or 60-minute, full-body massage, except at Banyan Tree Mayakoba, where massages start at a minimum of 90 minutes.
