The coastline is 2254 kilometers long. The Andes runs through the north and south, and the mountainous area accounts for 1/3 of the national area. The whole territory is divided into three areas from west to east: the west coast is a long and narrow arid zone, a tropical desert area with dry and mild climate, intermittent plains, developed irrigation agriculture and concentrated urban population; The central mountainous plateau area is mainly in the middle of the Andes, with an average elevation of about 4300 meters. This is the birthplace of the Amazon River, and the temperature changes greatly, with an annual precipitation of 200- 1 1,000 mm. The eastern part is amazon rain forest District, which belongs to the upper reaches of the Amazon River and is a foothill alluvial plain. This is a newly developed oil-producing area, with high temperature and rain all year round and forests everywhere. Mount Korobona and Salkan Mountain Ba Dou are over 6,000 meters, and Mount Vascalan is 6,768 meters above sea level, which is the highest point in Peru. The main rivers are Kaiali River and putumayo River. Western Peru has a tropical desert grassland climate, which is dry and mild, with an annual average temperature of 12-32℃.

The coastline is about/kloc-0.000 km long, 4,352 km long from north to south, 96.8 km narrowest from east to west and 362.3 km widest, making it the narrowest country in the world. East is the west slope of the Andes, accounting for about1/3 of the whole east-west width; There are coastal mountains with an altitude of 300-2000 meters in the west, most of which extend along the coast and enter the sea to the south, forming many coastal islands; The middle part is a sunken valley full of alluvium, with an altitude of about 1200m. There are many volcanoes and frequent earthquakes in the territory.
