By Metro
Metro stations are not conveniently located to the Coyoacán center-- don't let the existence of a Coyoacán station Line 3 fool you. Be prepared for at least a twenty minute walk from any of the nearest stations: Coyoacán, Viveros, and Miguel Ãngel de Quevedo all on Line 3. The neighborhood is safe, so you shouldn't have a problem if you decide to walk from the metro. You may also approach from General Anaya station Line 2; take the Calle 20 de Agosto exit for a picturesque twenty minute walk to the Frida Kahlo and Leon Trotsky museums.
By Microbus
If you don't fancy a 20 minute walk from Metro Coyoacan to the main square Plaza Hidalgo, you can take a microbus also known as a Pesero. These are the small green and grey busses that can be seen breaking road rules all over the city. As you leave either exit of Metro Coyoacan, cross the to the other side of the large road directly outside the metro Av Universidad. Peseros will stop outside all metro stations, and all display their destinations in the front windscreen. Look for a sign saying Plaza Hidalgo, or ask the driver.
