Cancún is a coastal city in the popular vacation destination called ''The Mexican Caribbean'', more officially known as the state of Quintana Roo, on Mexico's Yucatan Peninsula. Cancún is the municipal seat of the Benito Juárez municipality and a world-renowned balneario and tourist resort. It is composed of fourteen miles of pristine white beaches shaped like a number "7", home of the Mayan archaeological wonders, turquoise seas, a bountiful underwater world, and world-class vacation amenities. It is still considered the gateway to the Mayan World (El Mundo Maya). Mayan temples and ritual sites are everywhere, some smothered by lush jungle, others easily accessible. The Cancun hotel zone is almost entirely built around the tourist industry. It abounds with all-inclusive resort hotels.
