Mexico has excellent in-country buses, as well as a plethora of local buses ranging from not-so-converted school buses to beauty min-vans. And VW vans, of course. Check out some photos of Mexico buses by clicking numbers above the picture, or learn more:
How to Catch a Local Bus in Mexico
Stand by the side of the road or city street, looking into traffic, and raise an arm when you see a bus approaching -- it will probably pull over. You can usually get off by hailing the bus driver at any point along the bus's journey. The buses often run on a schedule; ask a local. The farther away from population centers you get, the farther apart buses will be (like hours or days), so ask someone, like a bartender or shop clerk, when the buses run in the area to which you're headed.
