Geographic information from Uruguay.
At 176,214 km2 (68,037 sq mi) of continental land 142,199 km2 (54,903 sq mi) of jurisdictional water and small river islands, Uruguay is the second smallest sovereign nation in South America (after Suriname) and the third smallest territory (French Guiana is the smallest). The landscape features mostly rolling plains and low hill ranges (cuchillas) with a fertile coastal lowland.
A dense fluvial network covers the country, consisting of four river basins or deltas; the Río de la Plata, the Uruguay River, the Laguna Merín and the Río Negro. The major internal river is the Río Negro (‘black river’). Several lagoons are found along the Atlantic coast.
The highest point in the country is the Cerro Catedral whose peak reaches to 514 metres (1,686 ft) AMSL in the Sierra Carapé hill range. To the southwest is the Río de Plata, the estuary of the Uruguay River which forms the western border, and the Paraná River.
Montevideo is the southernmost capital city in the Americas, and the third most southerly in the world (only Canberra and Wellington are further south).
Uruguay has 660 km of coastline.
There are nine National Parks in Uruguay. Five in the wetland areas of the east, three in the central hill country and one in the west along the Rio Uruguay
