Ibera Wetlands

Ibera Wetlands stands out as one of the largest freshwater wetland ecosystems on Earth, spanning over 1.3 million hectares. Its extraordinary wildlife density—featuring caimans, capybaras, and more than 350 bird species—outperforms #2's typical wetland bird counts by nearly 50%. Visitors can kayak through flooded forests, a unique experience that costs under $30 per person, cheaper than the average ecotourism destination in Argentina, while witnessing one of the continent's richest biodiversity hotspots.
