Travel distances within Cancún are not great and a variety of public transportation options are available, although many expats rely on their own automobiles.
The best way to get around the city is by bus. Busses stop frequently on the Boulevard Kukulcan in the Hotel Zone, as well as Avenida Tulum in the downtown area. You can flag down a bus driver on these major thoroughfares to get on the bus. Once you get on the bus, make sure you use the stop-request button located above the handrail to get off. One-way fares generally are less than US$.50. Bus One – an air-conditioned bus that travels within the Hotel Zone – costs about US$.60
To travel from Cancún to cities along the Riviera Maya, there are regional buses that leave from the city’s downtown bus terminals. Bus fare on the ADO GL deluxe bus between Cancún and Tulum is a little over US$9 and the ADO First Class bus is about US$7.
Taxis are plentiful in Cancún, and fares are charged by the number of zones you must travel through to your destination. The average starting fare is about US$1.60 and the first mile is about US$1.90. Taxis outside a hotel or restaurant tend to be more expensive than those hailed in the street.
