Quantities of regions in Nepal have only recently become identified to Tourists and development is still in its early life. These treks are away from the more popular trails and provide a wilderness experience in both natural and cultural aspect. You can observe the isolated mountain villages of Nepal where people are surviving by growing their own food. People are unaffected by modern civilization, no politics but they have a quite happy life with their own civilization and Culture. Exploring these areas gives different pleasures to the trekkers.
Actually these treks give you a very special experience of the real Nepal. In some remote land of Nepal there are no tea house/lodges on the track. So the fully organized camping is only one option.
