The Andes are by no means the only region to visit in Peru . Also of great interest is Peru 's narrow, lowland coastal region, a northern extension of the Atacama Desert . Although the Atacama is generally known as the most arid region on the planet, the climate along Peru 's shores is made cooler and less dry by La Garuùa , a dense fog created by the collision of the frigid waters of the Humboldt Current with the heated sands of the Atacama. Lima , Trujillo , and Chiclayo , three of Peru 's major population centres, are located along this coastal desert.

Peru 's climate varies considerably by region, although January through March tends everywhere to be the wet season. The coastal areas, which are quite hot and humid during those months, are cooled during the rest of the year by La Garuùa. The fog doesn't penetrate very far inland, however, and the western side of the Andes are very clear, warm, and dry for the greater part of the year. As one moves up into the mountains, night-time temperatures become considerably colder. The eastern slope of the Andes , like the Amazon basin, experiences very heavy rainfall during the wet season, which extends from January all the way through April.

Perhaps no other country has more to offer the visitor than Peru : panoramic mountain ranges, vast deserts, beautiful beaches and tropical jungle. All this combined with a rich historical and archaeological past and enduring indigenous cultures.

Peru is divided into the three main geographical zones of costa (coast), sierra (mountains) and selva (rainforest). Such diverse landscape generates diverse pleasures; Peru successfully offers history, archaeology, sports, beaches, mountains, medicinal springs, nature, fantastic landscapes, friendly people and mesmeric music. Ancient archaeological remains and Nazca Lines augment Peru 's sense of mystery.
