The Urubamba river or also called Vilcanota river derives from the quechua language Urupampa which means “plateau of spiders”, is one of the main and important rivers of Peru, important source of the tributary of the Ucayali river and the Amazon basin.
The course of the Urubamba River protects the areas of the Machupicchu Sanctuary, Megantoni Sanctuary and the Otishi National Park through the Lower and Upper Urubamba River.
The sacred valley of the Incas settled on the banks of the Vilcanota River, which in its lower course is called Urubamba River, the meaning derives from the Quechua word Willcamayu or Sacred River, Some chroniclers and theories indicate that the Incas called it sacred because the Urubamba River joined with the Milky Way according to the Andean cosmology, because as we know the Incas were excellent astronomers, which devoted many years to study their god the Sun (Inti), the stars and the moon.
CHARACTERISTICS OF THE URUBAMBA RIVER
The Urubamba river is born in the Vilcanota knot, in the department of Cusco in Peru, where most of its waters pass through the region of Cusco and take the name of the Vilcanota River, and when it passes through Urubamba it takes the name of the Urubamba river. Thanks to the river the Sacred Valley or Urubamba Valley has a temperate climate throughout the year, suitable and conducive to develop agriculture.
The Urubamba River, passing through Ollantaytambo, narrows, geographically a rugged area of the Torontoy Canyon where Machupicchu is located until it reaches the Mainique lake towards the Amazon.
It has an area of 58,734 km2.
