Have you ever been to the ‘Costanera Sur’ ecological reserve? Located in the center of Buenos Aires, this place has a strange history. When you are in the nature reserve, you are standing on a piece of land that didn’t exist 30 years ago. Can you guess what you are walking on?

In the 70’s and 80’, many buildings were destroyed during the construction of the freeways in the city. In 1978, when the government decided to expand the city center by gaining grounds on the Rio de la Plata, they decided to use the debris from the former buildings. Six years later, the project was abandoned and the land was quickly used as a base for nature to spontaneously grow on and the creation of different ecosystems. The nature reserve is now home to more than 250 bird species, reptiles and small mammals. The observation of animals is a popular activity and you can see many people walking around with binoculars. If you don’t have your own binoculars, a few pesos will allow you to peek through the public binoculars that are placed along the side of the walkway.

The natural reserve is also a great place to work out as there are multiple trails available (from 1 to 8 Km). If you’re not a big runner, a good option is to rent a bike at the southern entrance (main entrance) to explore the reserve. Or you can choose to do the ‘South of the city’ bike tour with Road2Argentina, where you will visit the ecological reserve.

On your way out, you can go for a well-deserved ice cream or drink at the Puerto Madero ‘diques’.
