About Cancun

Caribbean-blue waters, ancient Mayan ruins and a legendary nightlife strip

Cancun straddles two worlds: a modern hotel zone built on a slender sandbar between the Caribbean Sea and a lagoon, and the ancient world of the Maya that surrounds it. The Hotel Zone's beaches — particularly Playa Delfines and Playa Langosta — offer some of the Caribbean's finest swimming, with water that shifts from turquoise to deep sapphire depending on the depth. An hour's drive south, the ruins of Tulum sit on a clifftop overlooking the sea, while Chichen Itza — one of the New Seven Wonders — lies two hours inland.

When to go: December to April is the dry season with calm seas and brilliant sunshine. Hurricane season runs June to November.
