Getting around in Mexico without a car is also quite simple because it has one of the best public transportation systems available.

Taxis are abundant and affordable. However, you should be wary of accepting a ride from one of the well known green "beetle" taxis (mostly in Mexico City) because they are considered dangerous (they have no back door, and therefore no escape route should the driver have bad intentions.) However, there are a multitude of other taxis that will take you anywhere you want to go.

Buses are ubiquitous in most cities with routes which spread across the cities in question and usually even include the more rural areas of town. They are incredibly inexpensive (generally about .35 per person).

If you want to travel throughout Mexico, you will find an extensive system of buses that will take you anywhere you want to go. There are two types of bus travel-budget and first class-and it's recommended that you always take first class. (The budget buses stop every couple of miles to pick people up from the side of the road, and generally don't have restrooms on board.)

Mexico City has a subway system that is extensive and affordable. It can get very crowded during rush hour, but keep in mind that the first two cars are reserved for women and children to keep their ride more comfortable.
