Key Geography Facts
1. Peru is the third-largest country in South America, after Brazil and Argentina, and ranks as the 20th largest in the world by land area.
2. About a third of Peru’s population lives in a narrow desert region along the Pacific coast, even though this area makes up only about 10% of the country’s total land area. The majority, however, live in the Andean highlands.
3. The Andes Mountains stretch the full length of Peru from north to south, forming the second-highest mountain range in the world and including Mount Huascarán, the country’s tallest peak at 6,768 meters (22,205 feet).
4. More than 60% of Peru is covered by the Amazon Rainforest, a vast and biodiverse region known locally as the selva, which is home to rare wildlife and potentially uncontacted Indigenous tribes.
5. Lake Titicaca, shared with Bolivia, sits high in Peru’s Andean highlands and holds the title of the world’s highest navigable lake at 3,812 meters (12,507 feet) above sea level.
