The Paraguay River is South America's fifth largest river, running from the Brazilian state of Mato Grasso to its confluence with the Paraná River in Argentina, of which it is the main tributary. It serves as part of the Paraguayan border with Argentina as well as with Brazil.
Landforms of Paraguay
The Paraná River is the second longest river in South America. Running through Brazil, Paraguay and Argentina, it becomes an alluvial basin before emptying into the Río de la Plata. The Paraná Delta consists of several islands known as the Islas del Paraná.
Stretching across Brazil, Bolivia and Paraguay, the Pantanal is a natural region encompassing the world's largest tropical wetland area. Although not as well known as the Amazon Rainforest to its north, this gigantic seasonal floodplain is also home to a staggering variety of plants and wildlife.
