Dolpo trekking is in the West-North part of Nepal. This is very charming place in Nepal Himalaya. This district was closed for trekkers until 1989 eventually it is open now although it is in the list of restricted area of Nepal. They wants to preserve the nature and culture of this region that is why it is called restricted area and you need special permit and you can stay there for certain time. If you visit there once then you wants to go back again and again. Lying in the rain shadow area of the Himalayas, the landscape resembles that of the Tibetan Plateau instead of the lush green monsoon watered hills elsewhere in Nepal, at comparative altitudes. The great people, very pleasant nature and unique culture, Tibetan descent who follow the Buddhist religion are the highlights of Dolpo trekking. Their language is closely related to Tibetan. The elevation of the trails is from 1650 meters to 5136 meters above sea level.
To the south is a large east-west valley system called Lower Dolpo, and to the west is Mugu, which lies beyond the sacred Crystal Mountain and the Kanjiroba massif. To complete Dolpo’s isolation, the Khyaklum and Mt. Dhaulagiri create a natural border to Mustang and Annapurna to the east. A combination of ancient animist beliefs, Tibetan Buddhism, and Bon religions predominate throughout the region.
There are a number of trekking options that run through Dolpo, they are all magnificent and provide some wonderful scenery. Most trekkers enter and exit Dolpo via the dirt airstrip at Juphal in Lower Dolpo. Alternatively, experienced groups could consider the more committing routes from Mustang (east) or Mugu (west), where trail finding and acclimatisation pose additional challenges. Perhaps the most beautiful place in Nepal is Phoksundo Lake, in the centre of Dolpo, which can be combined with trails to Shey (Crystal Mountain) to access Bhijer, Saldang and the northern villages, or Dho Tarap and the valleys to the east. There are also route options that follow the Bharbun Khola, through Chharka Bhot and even to Hidden Valley to the north of Dhaulagiri.
Most of Dolpo trekking lies on Dolpa and eastern Mugu district, protected by the Shey Phoksundo National Park and Buffer Zone which covers a massive 3555 km2 and is the largest such park in Nepal. Referred to as a Trans-Himalayan Ecosystem (the lower, lush valleys of the mid-hills are linked with the arid Tibetan plateau), this is a culturally and environmentally sensitive and fragile region, which demands the utmost respect and care.
