Half of the overall site of Dos Ríos is given over to a nature reserve, which occupies the whole area behind the lots in the centre of the site, and consists of a wooded area of ceibo trees (the national tree of Argentina which produces vivid red or coral-coloured flowers). A path around the perimeter of the reserve offers over 4 kms of trails and provides access to the pool and barbecue area from each of the lots, and also provides opportunities for walking, bird watching, and cross-country running for the intrepid.

The Reserve attracts a large number of birds, including hummingbirds, tanagers, orioles, scarlet-headed blackbirds, kingfishers, woodpeckers, guans, duck, wren-like rush birds, horneros (the national bird of Argentina), chajá (the Southern Screamer), caracara, snail kites, forked tailed flyer catchers and kiskadees, to mention some of the most common. Bird watching walks can be arranged for those wanting to identify their avian neighbours.

At night the sound of frogs and crickets singing complements the sight of fireflies and the brightness of the southern stars.

Carpincho (Capibara) and Nutria, as well as guinea pigs and possums can also be seen.

Already more than 70 species of birds have been identified on Dos Rios.
