The Cancun edge

Cancun puts you an easy day trip from Cozumel's reefs while giving you nightlife, ruins and cenotes the island cannot.

Cancun is the rare beach destination that also works as a base. The airport is one of the busiest in Latin America, the transfer to your hotel takes twenty minutes, and within two hours you can be swimming in a cenote, climbing a Mayan pyramid, snorkelling the second largest reef on the planet, or eating cochinita pibil in a downtown market for the price of a coffee elsewhere. That combination is why we keep building these comparisons and keep reaching the same conclusion.
