By car (or taxi) - it takes about 45 minutes from the Mexico City, city center if you use the toll highway. It takes much longer, but more interesting, if you use the old free road. There is a small fee for parking at the site. A taxi may be prohibitively expensive, though sometimes "tours" with a car and driver/guide can be arranged for a reasonable fee if you want the convenience.
By bus - Buses to Teotihuac�n leave from Mexico City about every half hour from two locations: Terminal Autobuses del Norte (outside Autobuses del Norte Metro station, Line 5) or from outside the Potrero Metro station (Line 3). A one-way ticket will cost $35 pesos. From Terminal del Norte, walk towards Gate 8. There is a ticket booth almost at the end of the concourse. Check that your bus goes to the site entrance of Teotihuac�n ruinas and not just to the town of San Juan Teotihuac�n nearby. From Potrero, exit the station and look for white buses that go to Piramides -- they mean the pyramids of Teotihuac�n. The trip will take around an hour, and the buses run until about 6pm -- check the last departure before you leave. You will be dropped off and picked up at Puerta 2 (Closest to the Pyramid of the Sun), or by the front gate. From there it's a 1/8th of a mile down the main road entering the complex; you will be picked up there as well.
By tour bus - most travel agencies offer half or full day tours to the site, often combined with the Plaza de las Tres Culturas and the Basilica of Guadalupe, both of which are outside the city center. It�s a convenient way to combine the three, but note our comments above about getting to the site early. The price is around $200. As with guided tours everywhere in the world, these tours will waste much of your time by promoting gift shops, but they are still a convenient way to get here for Mexico City-based tourists
