Once in La Boca, head straight for the bright colours of the Caminito street museum. Until 1920, this passageway was a railway line; now it's a pedestrian street famous for its colourfully painted houses made of corrugated sheets of metal. The street is so unique that it's become the eighth most photographed place in the world.
For very different artistic styles, check out the Fundación Proa, a contemporary arts space with a terrace café that boasts excellent views over the old port.
To continue exploring, take a walk up the narrow Calle Garibaldi beside the train lines. This street recreates the feel of the neighbourhood at the start of the 20th century. Four blocks on is Boca Juniors' stadium, La Bombonera, an obligatory stop for all football fans. Another option it to take a look at the Usina del Arte, a former electricity plan turned cultural centre.
-The city tourist board offers guided tours of La Boca exploring the neighbourhood's history of immigration, football and tango every Wednesday at 11am in English and 3pm in Spanish.
-There are guided bicycle tours every day from 10am.
If you're lucky enough to be in the city at the right time, the Boca-River derby at La Bombonera is the most intense sporting fixture in the world according to the Observer newspaper in the UK.
From the Usina del Arte, walk to the junction of Necochea and Villafañe and take bus number 29 to Parque Lezama.
