Parque Provincial Pereyra Iraola

Parque Provincial Pereyra Iraola is a large protected area in the southern part of Buenos Aires Province, spanning across the municipalities of Berazategui, Ensenada, Florencio Varela, and La Plata. The more than ten thousand hectares include wetlands, woodlands, and open grasslands where native plants grow alongside animal species that have become rare in the heavily urbanized region.

The government under General Juan Domingo Perón acquired the Pereyra Iraola family estate in 1949 and converted it into a public park. Decades later, the area gained international recognition as a UNESCO Biosphere Reserve in 2007.

The name honors Leonardo Pereyra Iraola, whose family owned the estate before its transformation. Today, residents from the metropolitan area come here for hiking and birdwatching, with weekends drawing noticeably larger crowds than the quieter weekdays.

Visitors should bring sturdy footwear and plenty of drinking water, as the marked paths lead through remote sections. Early morning hours work best for wildlife watching, when birds and other creatures are most active.

The reserve protects the last significant riverside ecosystem in the densely populated region around Buenos Aires. More than two hundred eighty bird species use the area as a stopover during their annual migrations between North and South America.
