Hacienda Tres Ríos

Years of environmental study preceded the 2008 opening of this all-inclusive resort, which occupies 326 acres of privately owned, painstakingly protected rainforest. By day, you can play Tarzan or Jane: swimming through mangrove-edged rivers or in the deep, fresh water of cenotes; tracking tropical birds; learning about native flora at the property’s botanical garden; or sunning on the white-sand beach. By night, settle into one of 273 modern-luxe suites, outfitted with locally sourced mahogany furniture, Mexican beige marble floors, and Caribbean views.
