Tsum Valley, nestled within the northern part of Gorkha District near the Tibetan border, is one of the most secluded and culturally rich trekking regions in Nepal. Once a restricted area, this hidden Himalayan valley was opened to trekkers only in 2008 and still remains relatively untouched compared to more frequented trekking routes. The name “Tsum” is derived from the Tibetan word “Tsombo,” meaning vivid, and the valley lives up to its name with its striking landscapes, sacred Buddhist monasteries, ancient art, and deeply spiritual atmosphere.
The trek winds through pine forests, glacial rivers, and cascading waterfalls, rising from the low subtropical villages of Arughat to the high alpine pastures surrounding Mu Gumba (3,700m). Along the way, trekkers experience authentic Tibetan-influenced culture, with encounters at monasteries like Rachen Gumba, Mu Gumba, and the Milarepa cave, an ancient meditation site linked to the revered Buddhist saint.
The region is part of the larger Manaslu Conservation Area, but the Tsumba people have preserved a distinct dialect, art, culture, and religion. Unlike many Himalayan trekking routes, the Tsum Valley is still rooted in non-commercial, subsistence-based living, making this trek an enriching journey both culturally and spiritually. This 16-day adventure is ideal for trekkers seeking solitude, sacred history, and panoramic views of the Ganesh Himal, Shringi Himal, and Boudha Himal ranges, all while camping under the stars in some of Nepal’s least explored territory.
