Discover more about Reserva Ecológica Costanera Sur

The Reserva Ecológica Costanera Sur is a remarkable testament to nature's resilience and the power of urban green spaces. Situated along the Río de la Plata in Buenos Aires, this expansive 865-acre reserve was once slated for development but has since transformed into a thriving ecosystem. What was intended to be an extension of the city became a sanctuary for diverse flora and fauna, offering a unique natural experience just steps from the city center. Visitors can explore a variety of habitats, from lagoons and grasslands to forests, each teeming with life. The reserve is a haven for birdwatchers, with over 300 species recorded, including herons, coots, and the iconic Southern Screamer. Walking and cycling trails wind through the reserve, providing ample opportunities to observe wildlife and enjoy the tranquility of nature. The reserve's history is as fascinating as its natural beauty. The land was reclaimed from the Río de la Plata in the early 20th century, initially intended for urban expansion. However, economic downturns and changing priorities led to its abandonment, allowing nature to reclaim the area. Over time, native vegetation flourished, attracting a variety of animal species and transforming the site into the ecological treasure it is today. Today, the Reserva Ecológica Costanera Sur serves as a vital green lung for Buenos Aires, offering a space for recreation, education, and conservation. It's a place where visitors can reconnect with nature, learn about the local ecosystem, and appreciate the importance of preserving urban wildlife habitats.
