Reserva Ecológica Costanera Sur on Postcard

"Just adjacent to the newest and most expensive neighborhood in Buenos Aires is an 865-acre ecological park. The Costanera Sur reserve is one of the few spots in the city that really embraces the beauty of Río de la Plata, the massive river that hugs Buenos Aires’ coastline. It’s also one of the last remaining green spaces rich with the area’s native flora and fauna, and the single best option for bird watching inside city limits.The reserve has several trails and cycling paths that offer panoramic views of the city landscape, with skyscrapers in the background and native plants in the forefront. It’s also a good spot for a quiet picnic, and an escape from the noise of the city. The ecological park is open every day except Mondays, with free entrance and tours you can book in advance (call ahead to schedule a tour in English). We recommend taking a tour at night on the Friday closest to a full moon." - MATADOR_NETWORK

"The Costanera Sur Ecological Reserve owes its creation to rubble from a highway construction project that was dumped into the river: As nature took over the landfill, new life emerged along the shoreline. Look out over the estuary—that spot on the horizon (on clear days, at least) is Uruguay. Glance back toward the city and admire the urban-rustic juxtaposition of cattails framing sleek steel towers. You could spend all day walking the trails here, so give yourself at least an hour; rent a bike at the main entrance to get around faster. There are free guided tours in Spanish on weekends, plus monthly bird-watching excursions and full-moon nighttime walks. By Travesías"

Beautiful natural area close to the city. Only wish it opened earlier because it gets hot by 10am and much of the wildlife is less active after that. Well-maintained trails, beautiful new boardwalks, and great views of Puerto Madero. Oh, and don't go to the river expecting pristine beaches. Haha

It is free to enter and close to the city. Enjoyed a really nice stroll here. Saw some critters and rested in the shade. I would advise that you take mosquito repellent. We were both bitten a number of times.

It is mostly a broad gravel road through a area with shrubs. One is not allowed to get off the road. If one does like many locals the beach can be accessed. The beach consists of manly erodet building parts speckled with quite some plastic. Just a few people are wading in the brackish water. On a saturday, lots of people are walkind, running, bicycling and just hanging around in some lawn resting places. Birds are singing, some plants flowering in spring time. Water is available at the entrances and the junction in the middle at the sea. There are also restrooms. The park closes at 1800. When expecting a kind US national park were you can explore nature freely, one will be disappointed. If you just want to get away from builings and traffic it is quite OK.

I wanted to do a nature walk in The Reserva Ecológica Costanera Sur while I made an escape the urban jungle and discover a natural oasis in the heart of Buenos Aires. The Reserva Ecológica Costanera Sur, an 865-acre park along the Río de la Plata, offers a welcome contrast to the city's vibrant energy. This expansive reserve boasts a surprising diversity of flora and fauna. Explore the network of trails and be amazed by the vibrant wildflowers, the towering trees, and the abundance of birdlife. Over 300 bird species have been recorded here, making it a paradise for birdwatchers. Bring your binoculars and observe water fowl, egrets, herons, ducks, and many other fascinating creatures in their natural habitat. Is a great spot if you are a birder and want to take some photos. As I strolled along the winding paths, both locals and tourists engaged in various activities such as walking, jogging, or biking. These well-maintained paths meandered through the park, providing picturesque routes for a serene stroll. Immerse yourself in the tranquility of nature as you explore the reserve. However, be vigilant during warmer months, as mosquitoes and gnats may disturb your peaceful journey. To ensure a comfortable and enchanting stroll, don't forget to bring insect repellent, wear comfortable walking shoes, and carry a water bottle.

Such a great park for a slow walk/jog in the morning. The atmosphere is very sporty and there are multiple decks available for bird watching

Such a beautiful place. There’s a little park and tons of natural areas. It’s a long walk. You can see the BAs port.

Artificial Origins: While it feels like a natural landscape, the reserve was created artificially. It began as a land reclamation project in the 1970s when the city dumped debris from construction projects into the Río de la Plata. Over time, nature took over, and what was once a wasteland transformed into a thriving ecosystem. Healing Nature: Due to its peaceful environment, the reserve has become a popular spot for mindfulness and relaxation activities like yoga, meditation, and tai chi. Wildlife Corridors: Reserva Ecológica Costanera Sur serves as an important wildlife corridor for species moving along the Río de la Plata and beyond. Its location on the banks of this major river makes it a crucial stopover for migratory species that travel along South America’s Atlantic coast.
