The crossing from Uruguay to Argentina takes just over an hour, but the distance between the two countries feels both shorter and greater than that. Colónia del Sacramento sends you off from a peninsula of colonial cobblestones; Buenos Aires receives you into a metropolis of nine million people and a century's worth of grief, grandeur, and literary ambition. The day is organized around walking — through a city of the dead, past a flower made of steel, through a garden that doubles as a fragment of the Belle Époque, and into a neighborhood that renamed itself after a writer.
The Crossing
The day begins with an early departure from Colónia del Sacramento, winding through the old town toward the Terminal Fluviomarítima Colonia on the waterfront — arriving by 8:30 am to check in for the 10:00 am sailing. Customs clearance happens at this end of the crossing — you exit Uruguay and enter Argentina simultaneously, collecting two passport stamps for a single ferry ride. The Colonia Express service crosses the Río de la Plata in approximately one hour and fifteen minutes, a broad brown estuary so wide that the far shore remains invisible until the skyscrapers of Buenos Aires finally rise out of the haze.
