In Buenos Aires, this was a 3 hour tour, with 12 stops that you can jump on and off at, including:
The famous Recoleta Cemetery, with many elaborate marble mausoleums, where Eva Peron is buried (along with some of the most important Argentines)
The Boca where the tango originated
San Telmo and the famous sunday market, with all the street performers:
There are some fantastic buildings and architecture and some of the streets are very wide (we counted 9 lanes going one way on one street! the city looks very Eurpoean.
We used the pass over 2 days doing a total of 3 circuits! By Monday afternoon we were tired but felt we had a much better idea of the city.
