West to Santiago de Chile (San Juis, Mendoza)
Buenos Aires is huge, and getting out of it can be a hassle. This method is not necessarily the easiest, and you could almost certainly hitch closer to the city.
Trenes de Buenos Aires runs some of the commuter rail lines in Buenos Aires, including Linea Sarmiento from Estacion Once. Estacion Once can be reached via the Subte from Stations Once (Linea H) and Plaza Miserere (Linea A). From there, you'll want to catch a train going to Lujan. Depending on the time and day, you may have to transfer at Moreno, though it is a seamless transfer and one that many others will be making.
Once you arrive in Lujan, you have a couple of choices. You could walk the several km to to highway, but that might not be your bag. There should be a bus waiting outside the station with a sign for the Basilica. Surely the most famous thing in Lujan, the Basilica towers above the city and region, and is truly quite striking. The bus is only a few pesos, and will take you right to the bascilica, which is a very short walk north from Ruta 7.
Ruta 7 is the primary highway (though still very small considering that) east-west across Argentina from Buenos Aires to Santiago de Chile, and everywhere in between. Once you get to Ruta 7, there is quite a bit of shoulder (though know that the traffic does not pick up the entire length of the highway!)
East to Mar del Plata trough ruta 2 and the coast. =
From whereever u are in Buenos Aires u need to get to Constitucion,end of the blue line of the south of Buenos Aires. It will cost u normal city fare 1.1 Peso (20 eurocents) and from there I recommend to take a train direction to La Plata. U will get out on train Hudson. Then do not go to the closest exit to the highway - I,Xsuzann have been caught over there by police and sent away.Cross the railway and head to the road which seems to be road going to the country - but its acctually exit for highway. U would have to walk about 2 km,but its worth that, as the cars dont go that fast on the exit and its highest probability that someone will take u! Xsuzann xsuzann
