Atacama Desert and Altiplano

Atacama is the driest desert on Earth and recent scientific studies demonstrated that the soil in the region is about 25-30 million years old. The Atacama landscape is characterized by highlands, volcanoes, salt lakes, lagoons, hot springs, strange rock formations and sand dunes. Famous natural landmarks include Licancabur Volcano, Valle de la Luna, the Tatio Geysers and the Atacama Salt Flat. Atacama also has a lot of indigenous culture and pre-Colombian archaeological relics which have been perfectly preserved by the dryness and minerals. Its brilliant, clear sky makes Atacama a famous place for star gazing. The southern Atacama desert is famous for bursting into flower after rare rainfall, exhibiting rare exotic flowers and stunning colours across hundreds of kilometres, in a phenomenon known as the Desert in bloom.

The Altiplano, meaning ‘high plain’ in Spanish, is a high plateau in the Andes Mountains located to the North-East stretching across the borders of Chile, Argentina, Bolivia and Peru. It is home to many active volcanoes and the famous Lake Titicaca which sits at 3,800m above sea level. La Paz, capital of Bolivia, is the biggest city of the Altiplano.
