VIII Travesía acuática ACJ

The approach to Colonia del Sacramento from the water, whether arriving by ferry from Buenos Aires or driving the coastal highway, reveals a skyline dominated by the 1857 lighthouse. Built atop the ruins of the 17th-century Convent of San Francisco, its white flash rhythmically sweeps the horizon, offering a navigation point that has guided vessels here for over a century. As you stand on the shoreline near the Club Artigas, the scale of the Río de la Plata becomes apparent; it is a massive, silty expanse where the horizon blurs, often softened by the frequent morning fog characteristic of the region’s humid subtropical climate.

Historical currents and coastal markers

Swimming in these waters means navigating through layers of maritime history. In 1680, a sumaca and a lanchón carrying essential reinforcements for governor Manuel Lobo foundered here, their loss fundamentally altering the defense of the colony against Spanish incursions. Today, as you pace your stroke, you are tracing the perimeter of a city transformed in the 1720s into a fortified port. The remnants of the coastal bastions—São Pedro de Alcântara, Santo António, and Santa Rita—still define the waterfront, providing a rugged, stone-lined silhouette that remains visible from the water throughout the event. Just offshore, the silhouette of San Gabriel Island marks the spot where Sebastian Cabot first landed in 1527 and where the Portuguese expedition established their initial foothold.

Race day reality

Organized by the Liga Nacional de Natación Master, the annual Travesía acuática ACJ challenges swimmers to contend with an environment where local lore and geography intersect. The dark folklore surrounding the nearby Calle de los Suspiros—a place whispered to be the final path for prisoners led to be drowned in the river—adds a somber weight to the coastal scenery. Participants should be prepared for water conditions that shift with the river's flow and temperature, which fluctuates significantly between seasons. The race, usually held in the heart of the summer, requires a steady rhythm to manage the breadth of this historic estuary, where the only certainty is the constant presence of the lighthouse beam cutting through the mist.
