Quintana Roo is a Mexican state on the Yucatán Peninsula. On its Caribbean coast, the town of Tulum offers seaside Mayan ruins, sandy beaches and undersea caverns. To the northeast, the resort city of Cancún is known for its nightlife, Nichupté Lagoon nature reserve and long beaches with coral reefs. Off Cancún's coast, the tiny, reef-fringed island of Isla Mujeres has nature trails and beachfront restaurants.
