Sitting just off the gorgeous Yucatan coast, Cozumel revels in its mythic white-sand beaches and world-class coral reefs. Yet Cozumel is also the last stronghold of the Mayas, who settled the island in 300 A.D. Residents still speak Maya, and sometimes wear traditional Mayan clothing. Nearby stand the great pyramids and temples of their ancestors.
