Shivapuri Nagarjun National Park is the ninth national park in Nepal and was established in 2002. It is located in the country's mid-hills on the northern fringe of the Kathmandu Valley and named after Shivapuri Peak of 2,732 m (8,963 ft) altitude. It covers an area of 159 km2 (61 sq mi) in the districts of Kathmandu, Nuwakot and Sindhupalchowk, adjoining 23 Village Development Committees.
The area has always been an important water catchment area, supplying the Kathmandu Valley daily with several hundred thousands cubic liter of water. In 1976, the area was established as a protected watershed and wildlife reserve. In 2002, it was gazetted as Shivapuri National Park, initially covering 144 km2 (56 sq mi), and extended by the Nagarjun Forest Reserve in early 2009 to its present size.
The park is located in a transition zone between subtropical and temperate climate. The annual precipitation of about 1,400 mm (55 in) falls mostly from May to September, with 80% during monsoon. Temperatures vary from 2–17 °C (36–63 °F) during the winter season, rising to 19–30 °C (66–86 °F) during the summer season.
