What Travellers Say
Reviews Summary
A vast, free nature reserve offering a welcome escape from the urban jungle, teeming with wildlife and scenic views of the city skyline. While the natural beauty is a major draw, some visitors note issues with the shoreline's condition and the presence of insects.
"What a beautiful place on the edge of the city. Free entry, two toilet blocks, lots of benches and seating around, I spent hours here! There are turtles, lizards and so many birds. Paths you can cycle or walk down, little walkways to explore and a slightly apocalyptic swamp full of wildlife."

"Shore was full of dead fish. Few tons I think, so the smell was appropriate. The water itself is yellow. I don't think I can recommend the shore for a visit."

"This is a really lovely park on the edge of the city. It seems to be really popular at weekends. I can see why, there is so much wildlife about, its teeming with birds of different kinds. I spent a few hours walking around the park, including down to the beach, which unfortunately, though popular, is not well kept. The footpaths however are and its easy to walk around the whole park. It’s great to see a nature sanctuary like this that people can enjoy. Well worth a visit."

Exploring the Reserve by Bike
When cycling, remember that while the reserve is generally safe, it's always wise to keep your bike secured if you stop. Some parking areas are available, and it's advisable to have a lock. The flat terrain makes it accessible for most, and it's a fantastic way to enjoy the fresh air and natural surroundings away from the city bustle.
Beyond the main circuit, there are smaller paths and areas to explore. Cycling allows you to easily access different viewpoints, rest spots, and observe the abundant wildlife at your own pace. It's a truly immersive way to connect with the nature within Buenos Aires.
Wildlife Encounters and Birdwatching
Beyond birds, the reserve is home to turtles and lizards, adding to the diverse fauna. The marshlands and lagoons are particularly rich ecosystems, supporting a vibrant aquatic life. While the Río de la Plata shoreline can sometimes present less appealing sights, the interior of the reserve teems with life waiting to be discovered.
For the best wildlife viewing, consider bringing binoculars. Early mornings and late afternoons often offer more active wildlife. Remember to tread lightly and observe from a respectful distance to minimize disturbance to the animals.
Navigating the Reserve and Essential Gear

Always stay aware of your surroundings and stick to designated paths.
