City Blues?
If you want to get out of the bright lights of Santiago, there is only one place to go, the Alameda Bus Terminal. The Alameda Bus Terminal is the main bus terminal in Santiago, and it can be easily reached via the Metro stop Universidad de Santiago. One quick note about this Metro stop, as it is sometimes referred to as Estacion Central. This is confusing because the stop immediately before is also called Estacion Central and it is the stop for the train terminal. So don't be fooled by the confusing names, and just remember to get off on Universidad de Santiago and you will be fine.
The bus terminal itself is street level above the Metro stop, so just follow the signs to the terminal. Once in the bus terminal you will find the two main and best bus services in Santiago, Tur Bus and Pullman Bus, dominate the ticket windows. Simply walk around the terminal and look at the destinations and prices on the boards around the ticket windows. You will find buses going to just about everywhere in Chile, and international routes to Argentina and Peru. Tickets are easy to buy and relativity cheap. For example, a round trip ticket to Mendoza, Argentina will cost you approximately $30. So if you have the city blues just hop on the Metro and head for the buses, and in no time you will be on your way.
