Colonia del Sacramento is located in southwestern Uruguay, separated from Argentina’s capital of Buenos Aires by the Rio de La Plata. The historic downtown area (Barrio Historico) of this charming city (often simply referred to as ‘Colonia’) has been inscribed on the UNESCO World Heritage List for its fine collection of colonial-era buildings. Begin at the Porton de Campo, the impressive city gate dating back to 1745, and then wander through the romantic Historical District, stopping in at some of the city’s fine museums along the way (such as the Museo Municipal and Museo Portugues). Climb the 19th-century lighthouse (Faro) for great views of the city, before sampling some of the city’s renowned local fare (Asado) and checking out some local music (such as 'candombe' bands).
