Bolivia (6,542 m) – Tallest Volcano in the World
Nevado Sajama is a long dormant volcano and, by some measures, the tallest volcanic mountain on Earth. It is also the tallest mountain in Bolivia, and one of the most prominent peaks in the Andes range. The centerpiece of Sajama National Park, Nevado Sajama has several claims to fame. For botanists, it boasts what may be the highest tree line on Earth at 5,200 m. For sports fans, it is the site of the highest soccer game ever played.
Sajama has certainly been known since pre-Columbian times. The area was explored by Europeans in the 16th century. Despite being a not too technically difficult climb, the mountain was not scaled until 1939. Because it is relatively easy to climb in favorable weather conditions, Sajama has become a popular climbing site, as demonstrated by hardy Bolivian soccer players in 2001.
Nevado Sajama is relatively isolated in the Bolivian Andes near the border with Chile, but is directly accessible by winding road to La Paz approximately 150 miles away. There are no other major cities or towns that are closer. Although Sajama is no longer active, visitors are forewarned that the area around the mountain is prone to seismic activity.
