TRAVEL || South America > Argentina + Uruguay

South American Cone

The Uruguay River separates the two countries of Argentina and Uruguay in South America. At the river’s mouth and confluence with the Paraná River is the Rio de la Plata estuary, the most densely populated part of both countries.


The regions of the Argentine Republic range from the mountainous Andes to semi-arid plains, alluvial rivers to fertile wine-growing regions, temperate zones to polar Antarctic zones.


The Oriental Republic of Uruguay is part of the southern cone region of South America, which sits along its eastern Atlantic seaboard within a semi-tropical temperate zone.
