Before the late 1960s there was little infrastructure in the Yucatán Peninsula, which means that most of the main roads and highways are relatively new, and the construction and expansion of highways, roads and thoroughfares (mostly to facilitate tourism) continues. Except in the downtown areas of Cancún and Mérida, car travel in the Yucatán is convenient and easy.
The bus system in the peninsula is reliable and inexpensive. First- and 2nd-class buses will carry you safely and comfortably between all major cities and towns, and most sites in between. Buses run from the peninsula’s major cities (Campeche, Cancún, Chetumal and Mérida) to most other parts of Mexico as well.
