Overview

This walk runs for 2.5 hours through the Reserva Ecológica Costanera Sur, the largest green space in the City of Buenos Aires at about 350 hectares. The route moves through wetlands, marginal jungle, thorn forest and grassland, the natural environments of the Río de la Plata coast, so the scenery shifts constantly for a city walk. The guide's GuruWalk page runs the tour in English and Spanish.

A wide path under huge gum and plane trees in the Bosques de Palermo in Buenos Aires, the small lake edge glinting beside it, joggers far away and from behind, hazy weekend morning light

The reserve holds more than 500 plant species plus butterflies, reptiles, amphibians and small mammals, and more than 300 bird species visit the site, which is why it has been declared a wetland of international importance. The walk also opens on a piece of aviation history, the Monumento Al Plus Ultra, before following the paths toward the Río de la Plata, described on GuruWalk as the widest estuary in the world and a strong backdrop for photographs.

It suits nature lovers and anyone who wants an outdoor walk on a visit to the city. There is no pickup: everyone meets at the Monumental Fountain of the Nereids at the reserve's south access, on Avenida Dr. Tristán Achával Rodríguez at Migone. Booking is free and you pay the guide what you think the walk was worth at the end.

Itinerary

Stop	What Happens
Meet At The Nereids Fountain	The group gathers at the Monumental Fountain of the Nereids, the south access of the Reserva Ecológica Costanera Sur, at Avenida Dr. Tristán Achál Rodríguez and Migone. Plan to arrive on your own; no pickup is provided.
Monumento Al Plus Ultra	Near the entrance stands a statue of Icarus commemorating the 1926 transatlantic flight of the Spanish seaplane Plus Ultra between Spain and Argentina. The monument marks a feat that took place on the Río de la Plata off the coast of Buenos Aires, on the shore where migratory shorebirds now arrive.
Reserve Trails And Coastline	The full route has 10 stops, of which the tour's own page publishes only the first. The walk continues through the reserve's wetlands, jungle, thorn forest and grassland toward views of the Río de la Plata, lasting 2.5 hours in total.

What To Expect From The Tour

A few practical points from the GuruWalk listing will help you prepare for a walk that is outdoors for its entire length.

Meeting Point. There is no hotel pickup or transfer. Meet the guide at the Monumental Fountain of the Nereids at the reserve's south access, the corner of Avenida Dr. Tristán Achával Rodríguez and Migone.
Walking Pace. Expect a continuous walk of 2.5 hours on the reserve's paths. The tour is described as ideal for nature and outdoor enthusiasts, so a reasonable level of fitness for a long stroll helps.
Birdwatching Kit. More than 300 bird species visit the reserve, and the tour is built around observing and listening to them. Binoculars are not listed as included or required, but anyone who owns a pair will get more from the stops.

Duration	Language	Meeting point	What it costs
2 hours 30 minutes	English and Spanish	Reserva Ecológica Costanera Sur, Av. Tristán Achával Rodríguez 1413	Free, pay what you want

Photography. The tour's page on GuruWalk promises photo opportunities of Buenos Aires nature and the Río de la Plata, which it calls the widest estuary in the world. Bring a camera or phone with charge to spare for the open water views.
Weather Planning. Every part of the tour happens outside in wetland and grassland habitat. Sun protection and water make sense on hot days, and rain gear on wet ones.
Languages. The walk is offered in English and Spanish according to the operator's page. Travellers who need a specific language can see it stated on the walk's GuruWalk page before booking.

Common issues. The tour's own page publishes only the first stop of a 10 stop route, so the exact path is not fully known before you book. No food, drinks or equipment are listed as included, and nothing is listed as excluded either. As with any free, pay what you want tour, guides work for tips, so the model relies on guests paying fairly at the end.
