Maroma, A Belmond Hotel

Thirty kilometers of unbroken Yucatán coastline frame this low-slung refuge where hammocks sway between palms and thatched roofs barely clear the canopy. Maroma predates the mega-resorts, and it shows—in the unhurried service, the hand-painted tiles, the sense that this beach belongs to the jungle, not the other way around. The spa treatments use Mayan herbs grown on-site, harvested each morning before the heat arrives.
