Andes Awe: Discovering the Highest Mountains in Argentina

Bordering the nations of Bolivia, Brazil, Chile, Paraguay, and Uruguay, as well as the South Atlantic Ocean, Argentina is the second largest country in South America.

Yet when it comes to the country’s natural wonders, they don’t always abide by national borders. Indeed, some of Argentina’s most outstanding areas of natural beauty are shared with other countries. For instance, Iguazú Falls straddles both Argentina and Brazil. Likewise, South America’s Andes mountain system stretches across the countries of Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela. And, while several of its mountains cross borders, Argentina is home to some of the tallest Andes peaks. Thus, the tallest mountains in Argentina are some of the tallest in the world.

Read on to learn about the highest mountains in Argentina, starting with the highest point in the country.

Extending over 5,500 miles down South America’s western coast, the Andes Mountains are spread through seven countries and are the longest continental range in the world. Some 30 percent of Argentina is covered by these natural wonders. Not only does this include some of the highest mountains in Argentina, but in the entire western hemisphere. And the biggest of all is Mount Aconcagua in the Mendoza region, which rises to more than 22,800 feet above sea level. Whilst originating from volcanic activity, Aconcagua is not an active volcano.

With its peak straddling the Argentina-Chile border, this dormant stratovolcano reaches an astonishing elevation of approximately 22,615 feet, making it the highest volcano on Earth. Despite its arid surroundings in the Catamarca province, Ojos del Salado surprises with a permanent crater lake, marking it as the highest lake of any kind in the world, and adding to the diverse wonders of Argentina’s highest mountains.

Another impressive volcanic peak joins the list of Argentina’s highest mountains in the form of Monte Pissis. Shared between the provinces of La Rioja and Catamarca, Monte Pissis was formed as early as 6.6 million years ago and is now extinct. Its highest peak has been measured as around 22,300 feet above sea level.

Llullaillaco is not only one of the biggest mountains of Argentina, but also bears the distinction of being the site of one of the world’s highest altitude archaeological digs. This fascinating mountain, marking the Chile-Argentina border, last erupted in 1877, and in 1999, unveiled its ancient secrets with the discovery of three impeccably preserved Incan mummies, adding a layer of historical intrigue to the exploration of Argentina’s highest mountains.

Cerro Bonete, another breathtaking spectacle among the tallest mountains in Argentina. Positioned in La Rioja province, Cerro Bonete’s summit stands at around 22,175 feet above sea level, showcasing the country’s consistent geological grandeur and reaching a riveting summit in our exploration of the biggest mountains of Argentina.

Soaring to an impressive height of approximately 22,050 feet, Mount Mercedario’s immense stature and breathtaking scenery make it a remarkable site, with rugged terrain and panoramic views from its summit. Located in the San Juan province, Mercedario is one of the most prominent entries among Argentina’s most famous mountains.

Our expedition through the towering peaks of Argentina draws to a close, leaving us in awe of the immense and varied natural wonders the country holds. From ancient volcanoes and historic discoveries to record-setting heights, the highest mountains in Argentina stand as a testament to the country’s outstanding geographical and natural allure.
