Most international flights arrive at Ezeiza Airport approximately 35km southwest of the city centre. You can change money within the terminal and there is a tourist information desk. To get to the city centre you can take the shuttle service run by Manuel Tienda León (the ticket office is inside the terminal) for US$14. Much cheaper, though slow and not advisable with a lot of luggage, is the #86 bus for which youll need to get coins for the ticket machine. A taxi downtown will cost about US$35.
Flights from neighbouring Latin American countries may arrive at Aeroparque Jorge Newberry, well within the city limits, while international buses arrive at the Retiro terminal, in the heart of thecity with easy access to the subway and numerous bus routes.
Buenos Aires has all the traffic problems you would expect of one of the worlds biggest cities. Nevertheless, public transport is cheap and, outside of peak hours, pretty efficient. There is a good, though slightly limited, subway system and an extensive network of colectivos, or buses. Once away from Ezeiza Airport, taxis are a good deal too.
Despite its size, much of central Buenos Aires can be covered on foot and, thanks to its logical layout, finding your way around shouldnt be hard. If you do get lost, however, follow the examples of locals and ask at one of the citys numerous newspaper kiosks.
Buenos Aires is generally well served by public transport. The citys underground, the subte, was the first to be constructed in Latin America. Recently privatised, its old glitzy stations (adorned with ceramic tiles portraying scenes of Argentine life) are now being renovated. There are five lines, labelled A to E; the fare of 50 centavos is valid for all lines.
Services operate from early morning to late at night on a fixed-fare basis; tokens can be purchased at booking offices.
Bus: Services are provided by colectivo minibuses operating 24 hours a day on an inexpensive flat fare; however, these are often crowded, particularly at rush hour, but are usually prompt. There are extensive bus services in other towns, including trolleybuses in Rosario.
Taxi: Available in most cities and large towns and can either be hailed on the street or found at taxi ranks. They are usually recognisable by their yellow roofs.
RAIL: Owing to severe underfunding of State railways and recent privatisation, all longhaul services have been disrupted, although some suburban lines have been greatly improved. The domestic rail network extends over 43,000km (27,000 miles), which makes it one of the largest in the world. Children under three travel free and children aged 3-11 pay half fare. There are three classes: air-conditioned, first class and second class. There are restaurant and sleeping facilities for first-class passengers. Second-class rail travel is good value. There are six main rail routes from Buenos Aires: Buenos Aires–Rosario (where one branch goes to Tucumán and Jujuy via Córdoba and the second branch goes to Tucumán and Jujuy via La Banda), Buenos Aires–Rojas, Buenos Aires–Santa Rosa, Buenos Aires–Mar del Plata, Buenos Aires–Las Flores–Quequén Necochea and Buenos Aires–Bahía Blanca (where a branch goes to San Carlos de Bariloche). Rail travellers are warned that once out of Buenos Aires information is very hard to come by.
