<map lat='-34.6' lng='-58.45' zoom='11' float='right' width='400' height='340' view='3' /> Buenos Aires is the capital of Argentina, with around 12 million inhabitants. It is probably not easy to hitchhike here.
West to Santiago de Chile (San Juis, Mendoza)
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.
Buenos Aires is huge, and getting out of it can be a hassle. It is recommended that you get to the edge of the metropolitan area. Buses and trains inside the metropolitan area are cheap.
One of the best spots is Lujan paytoll (Peaje Lujan). You can take bus 57 and ask to be dropped at the toll. There are many different routes of Bus nr. 57, and it is convenient that you take the one leaving from Moreno. Once a bus driver told that only the ones leaving from Moreno have official stop at the paytoll because they take the workers there. The same bus driver, on a Bus nr. 57, leaving from Miserere, Capital Federal wanted to refuse to stop at the toll. In the end he stopped anyways.
Another good spot is the YPF petrol station of San Andres de Giles, most of the trucks that are going west stop there because the gasoil is cheaper than the Shell petrol station near Lujan. To go there take the bus 267 from the bus terminal of Lujan and ask the driver to drop you at the YPF petrol station of San Andres de Giles.
You can go to Moreno by train from Estacion Once and then change there to bus 57, route "Rapido". Estacion Once can be reached via the Subte getting off at Estacion Once (Linea H) or Plaza Miserere (Linea A).
Once in Moreno, to find the stop of bus 57, from where the train leaves you, take the bridge over the rails, to the road with many people. There you turn left, walk 1-200 meters, pass by the street which crosses the train lines, and Lujan buses will be facing you.
If you decide to take Bus nr 57 from Capital Federal, you have to get on the one that goes on the motorway "por Acceso Oeste". The route according to GuiaT is: Plaza Italia - Av. Santa Fe - Av. Raul Scalabrini Ortiz - Murillo - Malabia - Luis Viale - Av San Martin - Cruce Av. General Paz - Av. San Martin - Perdriel - Int. A. Campos - Dr. Carillo - Av. J. D. Peron - Av Dr. Ricardo Balbin .... and a lot more. Street names get repeated once you get out of Capital Federal, consider that. Also you can take Bus nr. 57 from Plaza Miserere. If you don't have SUBE card, in most of the stops you have to pay about 20 pesos in coins, or ask someone to pay with their SUBE card for you.
In Both cases you can also decide to not get off at the Lujan toll, but stay on the bus until Basilicum de Lujan, that is also a good spot at the exit of the city Lujan.
For those hitching to Chile, remember that taking food through the border is prohibited.
East to Mar del Plata trough ruta 2 and the coast
From wherever you are in Buenos Aires you need to get to Constitucion, end of the blue line of the south of Buenos Aires. It will cost you the normal city fare of 1.1 Peso (20 eurocents) and from there it is recommended to take a train direction to La Plata. You will get out on train Hudson.  Then do not go to the closest exit to the highway - Xsuzann has been caught over there by police and sent away. Cross the railway and head to the road which seems to be a road going to the country - but its actually an exit for highway. You would have to walk about 2 km, but it's worth that, as the cars don't go that fast on the exit and it's very likely that someone will take you!
This option is for those looking to get to Iguazu. From the main train station Retiro take Linea Suarez. In Villa Ballester change to the one going to Zarate (you should buy a ticket for this one). You can get off in Campana. Buses to Campana peaje pass on the street in front of Campana railway station. They go around the park and turn right at the corner of it.
This is a long way to get to the hitching point. The train is slow and you have to wait for connection in Villa Ballester. A more direct way is to take a bus to Zarate, one that takes the freeway. There should be buses from Plaza Italia (on Santa Fe, the northern side of Plaza Italia), but this information needs revision.
