A vast country reaching from the subtropical north to the glaciers of Patagonia, with Buenos Aires at its heart, the elegant capital on the River Plate that once styled itself the Paris of South America. Read the founding square of the Plaza de Mayo and the grand boulevards that lead from it, wander the marble avenues of the Recoleta Cemetery, and feel out the cobbled birthplace of tango in San Telmo. A city of squares, cafes, and boulevards made for walking, best taken slowly at your own pace.
