Destination guide
Cancún: Caribbean water three hours from most of the US
Cancún is the most-flown international destination from the United States, with nonstops from more than 40 US cities. The Hotel Zone's beaches, the Riviera Maya's cenotes and Mayan ruins, and all-inclusive resorts keep it competitive year-round.
Best time to visit: December–April is dry and sunny (and priciest around Christmas and spring break). May–June and November are warm with lower fares; August–October brings the highest storm risk and the cheapest all-inclusive rates.
