In the western area of the Buenos Aires conurbation, natural reserves are becoming established as accessible vacation alternatives. These spaces preserve wild environments and support a remarkable biological diversity.
Additionally, their trees act as a thermal buffer against increasingly frequent heat waves. Therefore, walking, learning, and playing outdoors becomes a healthy and educational experience.
Thus, family proposals combine recreation with environmental awareness, without the need to travel long distances.
Hurlingham and its great urban lung
The Hurlingham Urban Natural Reserve is the most extensive green space in the municipality. It is located at Juana Manuela Gorriti 3680, in William C. Morris, and protects about 49 hectares.
There, more than 9,000 trees of 240 species coexist, along with a varied local fauna. At the same time, it conserves more than 200 exotic forest species planted over six decades ago.
With free entry on weekends, it offers a butterfly garden, children’s games, and a circular library that promotes community book exchange.
Morón: reserves between history and biodiversity
The district of Morón has two complementary protected areas. In El Palomar, the Urban Defense Reserve, located at Derqui and Corvalán, covers more than 100 hectares.
This space allows for bicycle tours and integrates sports activities with environmental conservation. Thus, social use coexists with environmental care.
In Castelar, the Urban Natural Reserve at Coronel Arena 3202 protects 14.5 hectares of native flora. There, hiking, wildlife observation, and visits to its public library are conducted.
Moreno and the Roggero ecological district
In La Reja, the Roggero ecological district presents itself as one of the largest green complexes in the west. With more than 500 hectares, it integrates the Los Robles Natural Reserve, the Estancia El Dorado, the Plaza Favaloro, and the Coastal Walk.
For the summer season of 2026, new accesses, self-guided trails, a botanical garden, and a nursery have been enabled. Additionally, recreational and educational services have been added.
The area allows for horseback riding, bicycle tours, and stays in campsites, cabins, or lodges, with differentiated rates for families.
The importance of natural reserves in large cities
Urban reserves play a key role against the advance of concrete. They regulate temperature, absorb carbon dioxide, and reduce the risk of flooding.
At the same time, they function as refuges for birds, mammals, and reptiles, maintaining biological corridors in highly urbanized contexts.
Finally, they bring nature into daily life, strengthen community bonds, and remind us that urban well-being also depends on caring for these green lungs.
