Corrientes and Ibera Marshes
Important water resources consisting of an extensive system of marshes, lagoons and a large river network, whose waters come from the abundant rains of the region. There are 31 marshes in the province which cover a surface of 14,900 km2 and that even reaches 20,000 km2 in the period of abundant rains (March, April and September). The biggest concentration of water in the littoral are the Ibera Marshes.
Ibera means "water that shines" in Guaraní. It has 7 lagoons and 43 smaller courses of water. With over one million hectares of marshes, this is the second largest marshland of South America. At present, this reserve is one of the most attractive places for adventure tourism such as photographic safaris, wildlife watching, horse-riding, canoe tours and trekking tours.
Some of the most important tourist centers of the province are located on the banks of the Paraná River: Paraná, capital of the province; Diamante, Victoria and Gualeguay. On the Uruguay river, the coast is completely different. The soft undulations of the colorful land, with its fine sand beaches and diversity of birds, stand out.
Concordia, the most important town of this coast has numerous beaches, campsites and sporting clubs. Between this city and Colón is the El Palmar National Park. Its 8,500 hectares protect the last habitat of the once abundant Yatay forest. The Yatay is an endangered palm tree due to the action of the cows.
