This is Shangrila or Lower Kachura (Upper Kachura later) in the northern areas of Pakistan.
This was established in 1983 by Pakistan Army and has a unique restaurant that is built on the fusleage of an aircraft that crashed nearby.
Shangrila is named after a book called 'Lost Horizon' in which James Hilton narrates a tale in which an aeroplane crashed and the survivors came across some Buddhist monks. These monks took them to a beautiful monastery filled with fruits and flowers. This place was called Shangri-la, a Tibetan word meaning 'Heaven on earth'.
