A visit to Colonia del Sacramento is one of the easiest and most popular day trips you can take from Buenos Aires. Cheekily referred to by porteños as the city's 49th barrio, Colonia actually belongs to Uruguay. We recently took the slow ferry across the river to check out this beautifully upheld colonial village.
Around the corner from the ostentatious Palacio Paz is the much more refined Palacio Noël, home to the Museo de Arte Hispanoamericano Isaac Fernández Blanco. The palace would be worth seeing in its own right, but together with the museum, it's one of Buenos Aires' cultural highlights.
