Unspoiled and still relatively unexplored, the Ibera Wetlands are undoubtedly one of Argentina’s hidden gems and one of the best spots in South America for wildlife

The Ibera Wetlands, Esteros del Ibera in Spanish, are the second largest fresh water wetlands in the world after the Pantanal in Brazil. Although relatively little visited by tourists the network of lakes, shallow water lagoons and floating islands of vegetation are an important habitat for a startling array of unique wildlife. You can expect to see families of capybara, watchful black caiman, orange marsh deer, the maned wolf, coypu (another form of rodent), giant otters and the rare giant anteater. The birdlife is similarly impressive particularly during the migration. Getting to the wetlands is an adventure in itself with some lodges only accessible by light aircraft.

Best Time To Visit Ibera Wetlands

The Ibera Wetlands can be visited all year round but it is extremely hot during the summer (January until March) which can be uncomfortable. The Autumn months of April and May are cooler and therefore a great time to visit. Spring time (September until November) brings the most amount of rain but the wetlands are at their most colourful at this time of year. These months are also the breeding season for lots of animals, so wildlife viewing is good. The winter months of June, July and August bring colder temperatures and it is low season for Argentina as a whole. The bird migration happens between September and April which is a great time to go for bird watching.
