This 3,555 square km expanse is made up of high mountain and trans-Himalayan ecosystems in the north of Nepal. It covers parts of the Dolpo (the land of Yak caravans and salt traders). The local culture is strongly influenced by Tibet. Lake Phoksundo (or Ringmo) is the park's centre-piece.

The park includes forests of blue pine, spruce, cypress, poplar, deodar, fir and birch. It is also a prime location for leopards and blue sheep (as well as the ghoral, Himalayan tahr, wolf, jackal and black bear). The park is also home to many species of resident and migratory birds.

Activities include trekking and mountaineering. Accommodation is available in the form of camping. To reach Shey-Phoksundo, fly to Dopla's Jufal Airport from Nepalgunj or Pokhara and then it's a three day walk.

The best seasons are March to May (high passes may still be covered with winter snow) or June to September for clear weather.
