Exploring Bolivia's Mountainous Heart: The Andes Range

Bolivia is a landlocked country in west-central South America, boasting rugged mountains, dense rainforests, massive salt flats, and a rich cultural heritage. The country is home to 3,780 named mountains, the highest of which is Nevado Sajama, at 6,542m (21,463 ft). The primary mountain range within Bolivia is the Andes Mountains, which runs along the country's western region and western border with Chile. The Andes are one of the world's longest mountain ranges, and in Bolivia, the range dominates the western third of the country and is the source of the foothills. The Bolivian Andes are composed of ranges or cordilleras, including the Cordillera Occidental, Cordillera Central, and Cordillera Oriental. These mountain ranges contribute to the country's diverse and captivating natural beauty, offering breathtaking landscapes, rich biodiversity, and cultural significance.

The Andes Mountains

Bolivia is home to the Andes Mountains, which run through the western region of the country. The Andes are one of the world's longest mountain ranges, stretching from Colombia and Venezuela in the north, down the western coast of South America to Chile and Argentina. The Bolivian Andes are characterised by dramatic peaks, deep valleys, and arid plateaus.

The Andes in Bolivia are made up of three distinct ranges or 'cordilleras': the Cordillera Occidental, the Cordillera Central, and the Cordillera Oriental. The Cordillera Occidental runs parallel to Bolivia's western border with Chile and is the drier and more volcanic of the three ranges. It is characterised by numerous volcanoes, some of which are active, such as Parinacota and Pomerape. The Cordillera Central is a transition zone between the other two ranges, with attributes of both. It is known for its deep valleys and rugged terrain, and includes prominent peaks such as Illampu, Ancohuma, and Huayna Potosí. The Cordillera Oriental, also known as the Eastern Andes Mountain Range, runs along Bolivia's eastern border with Brazil and is the wettest of the three ranges, featuring dense forests, deep canyons, and a tropical climate.

The Cordillera Real is a sub-range of the Cordillera Oriental and is home to some of Bolivia's highest peaks, including Illimani and Illampu. It is known for its jagged peaks and challenging mountaineering opportunities. The Cordillera Apolobamba is located in the northern part of the Cordillera Real and is characterised by pristine landscapes, glacial lakes, and remote communities.

The Andes in Bolivia offer breathtaking landscapes, rich biodiversity, and cultural significance. They provide opportunities for outdoor recreation such as hiking and trekking, and are home to a number of national parks and protected areas, including Tunari National Park, Sajama National Park, and Eduardo Avaroa Andean Fauna National Reserve. The Andes are also an important source of natural resources, including minerals and natural gas.

Cordillera Real

The Cordillera Real is a mountain range in the South American Altiplano of Bolivia. This range of fold mountains, largely composed of granite, is located southeast of Lake Titicaca, and east of the Bolivian capital of La Paz. The range stretches 125 km in length and 20 km in width. Even though it is only 17° south of the Equator, the Cordillera Real is relatively densely glaciated. This is due to its proximity to the Amazon lowlands with its associated moist air masses.

The Cordillera Real is a mountain range belonging to the Andes, specifically to the Cordillera Oriental. It is located in Bolivia, to the East of La Paz, and in Ecuador. It is separated from the Cordillera Occidental by the highlands. When Spanish conquerors arrived in the mid-16th century, they were so stunned by the beauty of the mountains that they called this range "Cordillera Real" ("real" meaning "royal" in Spanish). In ancient times, these mountains were worshipped by the local Aymara civilisation, but they were not climbed due to their glaciers.

The highest mountain in the Cordillera Real is Illimani at 6,438 metres (21,122 ft). Other notable peaks include:

• Janq'u Uma, 6,427 metres (21,086 ft)
• Illampu, 6,368 metres (20,892 ft)
• Layqa Qullu, 6,166 metres (20,230 ft)
• Ch'iyar Juqhu, 6,127 metres (20,102 ft)
• Wayna Potosí, 6,088 metres (19,974 ft)
• Chachakumani, 6,074 metres (19,928 ft)
• Pico del Norte, 6,070 metres (19,915 ft)

The Cordillera Real is one of the prime destinations for climbers from all over the world due to its altitude, alpine climbing, accessible routes, and favourable weather conditions throughout most of the year. The best time to climb in the Cordillera Real is between May and September when the weather is dry and stable.

Apart from climbing, the Cordillera Real also offers magnificent landscapes for hiking and acclimatisation. The range extends from the northwestern tip of Lake Titicaca to the southeastern suburbs of La Paz and is about 125-150 km long. The northeastern flank of the Cordillera Real, known as the Yungas, features steep, almost inaccessible slopes and peaks with lush vegetation. The land is among the most fertile in Bolivia but has seen hindered agricultural development due to poor transport.

Cordillera Occidental

The Cordillera Occidental, or Western Cordillera, is a mountain range in Bolivia that is part of the Andes. It is one of two parallel ranges that surround the high plateau, the Altiplano. The range begins in the north at Juqhuri and ends in the south at the Licancabur volcano, which is on the southern border of Bolivia with Chile. The climate in this region is cold and unsuitable for animal and plant life.

The Cordillera Occidental is divided into three sections:

Northern Section

The northern section contains the highest peaks in Bolivia, the tallest of which is the volcano Sajama at 6,542 meters (21,463 feet). This makes it not only the highest peak in the Cordillera Occidental but also the highest in all of Bolivia. Sajama is perennially covered in snow. Other volcanoes in this section include Pomerape and Parinacota (called Payachata collectively), the latter being a dormant volcano with a cone of snow similar to Mount Fuji in Japan.

Central Section

The central section is situated between Uyuni and Coipasa. Its most prominent summit is the Ollagüe (Ullawi) volcano on the border with Chile.

Southern Section

The southern section is characterized by volcanic activity, sandstorms, and fog. It is home to the Licancabur volcano, which rises to 5,920 meters (19,423 feet). However, only two-thirds of the northeastern slope of the volcano belongs to Bolivia, up to an elevation of 5,415 meters (17,766 feet). The lakes Laguna Colorada and Laguna Verde are found on Licancabur and are named for their respective colours.

The Cordillera Occidental is known for its volcanic activity and the presence of large quantities of metallic minerals, including gold, silver, and copper. It is a natural border between Bolivia and Chile and boasts breathtaking landscapes that attract tourists and adventurers alike.

Cordillera Central

The Cordillera Central, or Cordillera Oriental, is a set of parallel mountain ranges of the Bolivian Andes. It is formed by the Central Andean fold and thrust belt.

The Cordillera Oriental can be divided into three sections: Northern, Central, and Southern. The Northern section is a continuous mountain range like Eslabón, San Buenaventura, Muchane, and Pilón. Some of its important summits include Astalaya and Cerro Colorado. The Central section is formed entirely by the Cochabamba mountain range, which crosses the department of Cochabamba and forms the Yungas and the Chapare. Its major summits include Tunari at approximately 5,035 meters and San Benito at 4,298 meters. The Southern section starts north of Chuquisaca with the Presto mountain range and ends in the Caiza and Capirenda mountain ranges in the Gran Chaco province in the department of Tarija. This section does not contain any representative summits.

The Cordillera Oriental extends into Argentina, where it is found in the provinces of Jujuy, Salta, and the northern part of Tucumán Province.

The Cordillera Oriental is characterised by its parallel mountain ranges, which often extend into forested and humid regions that are rich in agricultural and livestock products.

Cordillera Oriental

The Cordillera Oriental, or Eastern Cordillera, is a set of parallel mountain ranges in the Bolivian Andes. It is one of the three main cordilleras, or ranges, of the Bolivian Andes, the others being the Cordillera Occidental and the Cordillera Central. The Cordillera Oriental runs along the eastern and northeastern margin of the Andes and is bisected by Bolivia from north to south.

The Cordillera Oriental is characterised by deep valleys, sharp ridges, and lush slopes that descend into the Amazon Basin. The northern section of this range is known as the Yungas, a semitropical valley area with steep, almost inaccessible slopes and peaks. The Yungas is ecologically diverse and agriculturally important, as it supports the cultivation of coca, coffee, and other crops. The biodiversity of this region is remarkable, hosting cloud forests that are home to a wide range of flora and fauna, including several species of orchids, ferns, birds, and mammals.

The Cordillera Oriental can be divided into three sections:

• The northern section is a continuous mountain range and includes the Eslabón, San Buenaventura, Muchane, and Pilón ranges.
• The central section was formed entirely by the Cochabamba mountain range, which crosses the department of Cochabamba and forms the Yungas and the Chapare.
• The southern section starts north of Chuquisaca with the Presto mountain range and ends in the Caiza and Capirenda mountain ranges in the Gran Chaco province in the department of Tarija.

The Cordillera Oriental extends into northwestern Argentina, where it is found in the provinces of Jujuy, Salta, and the northern part of Tucumán Province.
