Costanera Sur Ecological Reserve
Reserva Ecológica Costanera Sur
A 350-hectare wetland east of Puerto Madero that evolved naturally on land built up from construction debris. Ride or stroll here to watch waterbirds, the Río de la Plata and the city skyline.
The reserve sits on land reclaimed in the 1970s and 1980s, where construction debris was dumped. Reeds, wetlands and woodland gradually developed naturally. It was designated a nature reserve in 1986, and more than 300 bird species have been recorded, along with capybaras, lizards and other wildlife. The main trail is a loop of about 8 km, which you can walk or cycle (there is an Ecobici station at the entrance). On the eastern side, you can reach the wide, muddy banks of the Río de la Plata and look back at the high-rises of Puerto Madero. Entry is free. It is open Tuesday to Sunday roughly 08:00–18:00 (longer in summer) and closed Mondays. The entrance is on Tristán Achával Rodríguez Avenue, where you will find a strip of food trucks famous for choripán, grilled sausage sandwiches. Bring water and sunscreen, and do not feed the animals.
