The Andes

The Spine of South America

The Andes, the longest mountain range in the world, stretches over 7,000 kilometers along the western edge of South America. This colossal range crosses through seven countries, including Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Home to iconic peaks like Aconcagua, the highest mountain outside of Asia, the Andes offer a stunning backdrop to the continent’s diverse landscapes.

The Guiana Highlands

Green Plateaus and Waterfalls

Encompassing parts of Venezuela, Guyana, Suriname, and Brazil, the Guiana Highlands are a vast plateau characterized by dense rainforests, tepuis (tabletop mountains), and impressive waterfalls. Mount Roraima, one of the world’s oldest geological formations, is a prominent feature of this region.

The Brazilian Highlands

Central Plateau of Brazil

The Brazilian Highlands, also known as the Planalto Central, cover a significant portion of Brazil’s interior. This expansive plateau features rolling hills, savannas, and cliffs, contributing to Brazil’s diverse topography.

The Patagonian Andes
