The vast “Esteros del Iberá” are the second largest wetlands in the world after Brazil’s Pantanal and cover some 1300 km² of marsh, savannah and lagoons in north-east Argentina at the heart of Corrientes Province. Despite being remote and inhospitable the wildlife is extraordinary and home to a dazzling array of flora and fauna including pampa deer, capybara, caiman, river otters, maned wolf and over 300 species of birds.
Access by air is via Posadas just across the river from Paraguay and there are a number of excellent lodges dotted around Carlos Pellegrini at the heart of the natural reserve. Journeys are long and bumpy yet the experience more than makes up for it.
