2) To get to “TAPO” bus terminal, make sure to get an authorized taxi at the airport. Authorized taxis are safe and have a fix rate. At the “TAPO” bus terminal there are several lines that go directly from Mexico City to Oaxaca, some of them are even more comfortable than the airplane (for example “UNO” line) , and rates are very reasonable (a one way ticket to Oaxaca City in UNO line is $546 pesos, about $50 dollars). You can check prices and schedules from TAPO to Oaxaca and back at www.ticketbus.com.mx – If you travel during the day, the drive from Puebla to Oaxaca passes through spectacular landscapes, including mountain cactus forest, which you will not regret seeing!!

Alternatively, if you wish to spend some time in Mexico City and visit our installations and National collections at the Instituto de Biología, UNAM, please use the authorized taxi cabs at the airport to get to your hotel or to the Institute.
 
If you decide to rent a car and drive, keep in mind that car rentals in Mexico are not that cheep. Mexican toll roads or highways (autopistas) are highly recommended for travel either by bus or with a rented automobile, but unfortunately they only connect major cities and other “autopistas” and they can be fairly expensive. Usually four-lane roads with adequate shoulders, are a lot quicker and in better condition than the alternative roads that have no cost (carreteras federales). Most “carreteras federales” are narrower, with only two lanes (one in each direction) and often no shoulders
