Cancún sits on the northeast tip of the Yucatán Peninsula, where a long, narrow sandbar shaped like a 7 separates the turquoise Caribbean from the Nichupté lagoon.
The best things to do in Cancún start with that water: wide white-sand beaches, snorkeling over reefs and underwater sculptures, ferries to Isla Mujeres and boat rides through the mangroves.
Behind the beaches lies the heritage of the Maya world, from small ruins inside the Hotel Zone to day trips to Chichén Itzá and Tulum.
Cancún is also a young city. It was founded on April 20, 1970, as a planned resort, and it has grown into a city of about 889,000 people according to the 2020 census.
Most visitors stay in the Hotel Zone along Boulevard Kukulcán, while downtown, known as El Centro, is where residents live, eat and shop, around Parque de las Palapas and Mercado 28.
The two are linked by frequent local buses, so it is easy to mix resort days with real Mexican street food.
This guide covers Cancún for every kind of trip, whether you have a long weekend, a family week or a longer stay that reaches the cenotes, Holbox and the Maya sites of the peninsula.
We organize the city by mood and traveler, with fun, free, family-friendly, adult, romantic, nighttime and rainy day picks, then move through the seasons and the neighborhoods so you can plan a trip that fits the way you like to travel.
