[edit] Site Information

This 865-acre (346-hectare) tract of low land is located on the RĂ­o de la Plata riverbank on the east side of the district of Puerto Madero in Buenos Aires, Argentina. It is used heavily by cyclists, walkers, runners, and picnickers, but still provides adequate solitude to allow quiet bird observation and photography. Early morning is the best time to visit for birding, before the crowds arrive. The area is built around several substantial pond/swamp areas, but these can be totally dry depending on season, rainfall, and water management priorities. If you are primarily interested in aquatic species, you should inquire as to the water situation.

[edit] History and Use

This reserve happened almost accidentally. In the 1970s, a huge land fill of construction waste was dumped here as a byproduct of highway construction. Sediment built up to form several large ponds and provide habitat of the native Llanura Pampeana ecosystem. Finally recognized as a significant resource in the 1980s, the government gave it official protection, and developed infrastructure such as pathways, plantings, and water management.

[edit] Areas of Interest

All the major paths are good for birding, and if there is water in the lowland areas, the wide sidewalk along the street outside the park boundary provides excellent views as well, even when the park is closed. Of especial interest are some popular picnic areas on the east edge next to the river, where birds are especially dense. These are accessed via small side roads that drop down from the main pathway on the east side.

[edit] Access and Facilities

There are two entrances:

  • The main entrance is at the corner of Av. Brasil and Av. Tristan Achaval Rodriguez where you'll find a sculpture from Lola Mora called 'Las Nereidas'.
  • At the corner of Viamonte street and Av. Tristan Achaval Rodriguez.

The reserve is closed on Mondays and Holidays! If closed, some worthwhile birding is sometimes possible along the western edge, on the broad pedestrian walkway. During the year it opens from 08:00 to 18:00 and in summer the opening hours extend to 19:00.

Security: This is part of a major city, so security might be a concern, but there are police officers at both entrances and park guards walking along the paths.

There are benches along the walkways for tired hikers. Parillas offer fast food and drink along the walkway west of the park boundary, and full restaurants are only a few blocks away.
