Holbox (Spanish pronunciation: [xolˈβoʃ], "black hole" in Yucatec Maya) is an island in the Mexican state of Quintana Roo, located on the north coast of the Yucatán Peninsula.

The island is accessed by ferry from the mainland town of Chiquilá,[4] and has virtually no cars, with transport by most residents and tourists by golf cart or moped.

Vehicle entry is not allowed at Holbox in order to protect the environment and to prevent the streets from accumulating sand.

Holbox has several alternatives to enjoy nature, but the one that attracts most visitors is the experience of swimming with the impressive whale shark from June to September, an opportunity found in very few parts of the world.

At the western tip of the island, there is a lagoon called Punta Cocos, where bioluminescence can be observed on dark nights.
