Tsum Valley Trekking is a trek through a secret valley. It is situated in Nepal's northern area, close to the Tibetan border. Tsum Valley is a treasure trove of history, culture, and religion. It was just recently made available to trekkers in 2008. Passing through a lovely village in the midst of a cultural and traditional hotspot can provide a real and true image of an ancient inhabitant who has remained unaffected by the outside world. With tea house accommodations, this trek will take more than a week.
