Home to the symbolic ramshackle colorful houses, working-class La Boca packs tons of tourist-priced shops and eateries into the little Caminito strip. No visit is complete without an outing to the nearby La Bombonera soccer stadium, where Boca Juniors fan regularly get rowdy. For culture-mongers, the fabulous Fundacion Proa art museum, located right on the Riachuelo harbor, hosts international exhibitions and has a world-class terrace cafe.
