A 1.3-million-acre UNESCO wilderness where freshwater cenotes drain through mangroves into the Mesoamerican Barrier Reef; the pre-Columbian Muyil canal allows for a sensory-rich 'float' through ancient trade routes; swim the clear brackish water at noon when the sun illuminates the limestone bed; the silence is punctuated only by the occasional call of an osprey or the rustle of manatee grass.
