Fly. Most flights arrive at Aeropuerto Internacional de Cancún. Several major carriers from the U.S. and Canada offer direct flight service to Cozumel and Mérida. Other nearby international airports include Chetumal and Capeche.
Take a cruise. Several major cruise lines offer service to the Yucatán, including Carnival, Princess, Norwegian and Mexico Cruises.
Drive. Feeling adventurous? Hop in a car or hire a rental car at the airport. Roads in the Yucatán Peninsula are generally smooth and well-maintained. Be careful of severe thunderstorms that can impair vision---especially at night.
Take a bus. Buses traveling to tourist destinations are clean and air-conditioned and have bathrooms. You can also take a cheaper combi, a car or van run by a collective, though these are generally crowded and hot.
