The first metrobus line (there are now 4, with more in the works) runs north-south along Insurgentes, and this is the line mostly likely to be used by tourists. It's often the fastest way to reach Coyoacán and San Angel in the southern part of the city. It has it's own lane and keeps moving even when other traffic is at a standstill.
A few tips: It can get pretty crowded during rush hours--I usually watch to see how full the buses going by are before I enter the station. Be careful of the badly designed doors! They close inside the bus so stand clear.
Station signs can be hard to read from inside a crowded bus, so I suggest you check the map first, and count the number of stations until your stop.
How to buy a Metrobus card:
1. Look for the machine at the station entrance that looks like the photo above.

2. Press the button RECARGAR
3. Put in the amount you want. The machine accepts all coins, and bills up to 200 pesos--but remember if gives NO change.
4. When you see the amount verified on the screen, take out your card.
How to use your metrobus card:
Just swipe your card at the turnstile and enter. One card can serve for any number of people, but be aware that it's often cheaper for a group to take a taxi.
If you are under 5 years old, over 70 (with proper ID: INAPAN, INSEN, GDF, or IFE), or are disabled you can ride for free.
