Buenos Aires is a relatively easy city to navigate, but if you've just arrived and want to take everything in on a guided tour, then you're really spoiled for options. General tours are offered on foot, bike or bus, and there are some great specialized options too; tango, Jewish, Evita, art and graffiti, murder mystery and even erotic tours are available! To find out more about the tours (some options are seasonal), check out the government tourist website www.bue.gov.ar which also offers download-able city guides and walking circuits so you can take yourself on your very own walking tour.
