The Puerto Madero Ecological Reserve, also known as the Reserva Ecológica Costanera Sur, is a 350-hectare nature reserve in the heart of Buenos Aires, Argentina. Its address is Av. Tristán Achával Rodríguez 1550, in the C1107 district of the city. For a visitor used to the streets, cafés and avenues of the capital, it offers a quieter kind of outing, with open water, grassland and wildlife within reach of the city centre.
What you will find
The reserve is built around its lagoons and grasslands, which together give it a varied landscape. Wildlife lives across these habitats, and the reserve is especially popular with birdwatchers who come to observe the species that gather there. Walking trails run through the site, so you can take your time and move between the water's edge and the open grass at your own pace.
Planning a visit
- Best suited to: birdwatching, slow walks and anyone looking for green space in the city.
- Getting there: the reserve sits in the Puerto Madero area, and its address is listed above for navigation.

Because the reserve is a natural area rather than a built attraction, it rewards patience. Bring comfortable shoes for the trails, and allow time to stop and look around. Pairing a visit with a walk through the nearby Puerto Madero waterfront makes for a balanced day, moving from the reserve's wild edges to the city's more polished riverside.
