# Alto Purús National Park

Alto Purús National Park (Spanish: Parque Nacional Alto Purús) is a national park in the Amazon rainforest of Peru, established in 2004. It covers an area of 2,510,694.41 ha (9,693.85 sq mi) in the provinces of Purús (Ucayali), Tahuamanu and Tambopata (both in Madre de Dios).
It is also home to a number of indigenous tribes, including some that have avoided contact with the outside world.

## Geography

Although the Amazon rainforest plain dominates the landscape, hilly terrain can be found in the western part of the park. The main rivers in the area (Purús, Curanja, Cujar and Curiuja) can have some sandy shores.

## Climate

Average annual precipitation in the area is 2600 mm, with heavy rains from December to April (which causes the rise of water level in rivers and streams), while the rest of the year is less rainy. The average temperature is around 25 °C, and can be as low as 17 °C and as high as 35 °C.

Cultural tourism can be done in the native villages along Curanja River, where local dances, fish farming and traditional agricultural practices can be observed.

## Environmental issues

Among the main threats to the park are: logging (especially of mahogany), hunting, overfishing, illegal settlements (promoted by corrupt local authorities), lack of park management and contact with peoples in voluntary isolation. In addition, some local groups support the construction of a road to the town of Esperanza, which will pass through the park.
