Central Buenos Aires is a great place to tour on foot, but like all capital cities it is large, so if you want to go further afield use the public transport.
Public transport in Buenos Aires is generally safe and efficient, the “Subte” (Subway/Underground) is the easiest to use. It serves the city centre and northern areas. To reach the rest of the city or go outside it’s best to use the bus service. There are also plenty of taxis which, surprisingly for a capital city, are not very expensive.
