Punta Rasa is the geographical feature that marks the limit of the Río de la Plata. It is the southern end of Samborombón Bay, within the Municipality of La Costa, 10 km north of the town of San Clemente del Tuyú.

In 1984 the Fundación Vida Silvestre Argentina signed an agreement with the Servicio de Hidrografía Naval, dependent on the Argentine Navy, to create an experimental biological station to carry out all kinds of studies related to the biodiversity of the place. In 1991 the area was declared a municipal nature reserve of the Partido de la Costa. The protected natural area is a site of great interest because of its importance for various species of coastal birds.
