Mar Chiquita

Mar Chiquita is a coastal lagoon in Buenos Aires Province that stays connected to the Atlantic through a narrow tidal channel. The water surface shifts constantly with tides and currents, while sandbars and dunes change shape across the seasons.

Native communities used the lagoon as a food source for centuries before European settlers reached the region in the 19th century. UNESCO granted the area biosphere reserve status in 1996, recognizing its ecological value.

Local fishermen maintain traditional fishing practices at the lagoon's sea connection, catching pejerreyes in winter and black corvinas during summer months.

The area works well for birdwatching, especially during migration periods in spring and autumn. Paths along the shoreline stay mostly accessible, though wind conditions and water levels affect daily conditions.

Salinity and water temperature fluctuate with seasons and rainfall, bringing different fish species at different times. Some Antarctic birds follow cold currents this far north and use the lagoon as a temporary stopover.
