Mustang, formerly Kingdom of Lo, is a remote and isolated region of the Nepalese Himalayas. The Upper Mustang was a restricted demilitarized area until 1992 which makes it one of the most preserved regions in the world, with a majority of the population still speaking traditional Tibetan languages.
Annapurna Base Camp trek gives an extraordinary variety of ecosystem because of the unique combination of depths and height. It is surrounded by the snow giants, especially Annapurna Himalayan ranges and other peaks above the 7000 meter mark. So, it receives only 7 hours sunlight a day in summer season. A dense tropical forest of bamboo and Rhododendron covered the south facing slopes and the north facing slopes are covered by rain shadow. The sanctuary is considered sacred by both Hindus and Buddhists as it is believed to be the abode of their deities.
