La Boca is the most colorful barrio in Buenos Aires. And the color extends beyond brightly tinted tin-roof buildings. Stroll the short yet vibrant Caminito Street, a pedestrian walkway cum outdoor museum. Observe artists. Take in a free tango show. Walk a few blocks to La Bombonera and, if your trip coincides with a Boca Juniors match, take in the “color” both in and out of the stadium.
