The beautifully marshy land of this 350-hectare nature reserve has become a popular site for weekend picnics, walks and bike rides. Bring binoculars if you’re a birder – over 300 bird species can be spotted, along with river turtles, iguanas and nutria. At the eastern shoreline of the reserve you can get a close-up view of the Río de la Plata’s muddy waters.

The park has a second entrance at the other end of the Costanera, from where free guided tours (in Spanish) depart at 9:30am and 4pm on Saturday and Sunday, November to March. From April to October tours depart at 10:30am and 3:30pm on Saturday and Sunday. Free night tours are also held one Friday per month (call for the latest schedule; reserve ahead).
