Fed by creeks from the Sierras de Tandil and sheltered by a chain of sand dunes, the lagoon Albúfera Mar Chiquita alternately drains into the ocean or absorbs seawater, depending on the tides. This creates a unique ecosystem boasting huge biodiversity, and is the only lagoon of its kind in Argentina. The spot is a paradise for bird-watchers, with over 220 species of birds, 86 of which are migratory, including flamingos. There are also over 55 fish species in the lagoon, making it a popular fishing spot.
