Tsum valley trekking is one another beautiful trek in Manaslu region. This trek is culturally and naturally distinctive. Where most people are Tibetan origins and rich in ancient art, religion, thousands of stone slabs carve with the deities, chortens, maniwalls, and prayer wheels, prayer flags hanging over the passes, houses and ritual sites. Geographically this Himalayan pilgrimage valley lies on the backdrop of Shringi Himal, Buddha himal and Mt. Ganesh himal. It is used to call 'Tsum Tso Chuksum', which means thirteen provinces ruled as a single territory in Tibetan language. Still, it is visible the ancient remains of the Tsum Kingdom.
