Tsum valley Trek is another interesting and beautiful trekking destination of northern parts of Gorkha District, Nepal. Tsum valley is also known as the Beyul Kyimolung, the holy hidden valley of happiness, first described by Guru Rimpoche (Padmasambhava) in the eighth century. It is also part of Manaslu Circuit Trek. 'Tsum' means 'Tsombo', in Tibetan word vivid in English. Traditionally, Tseum valley was culturally distinct geographical areas called “Tsum Tso Chucksu’s” which means thirteen provinces ruled as a single territory. Milarepa meditated in the caves of Piren Phu and there are centuries old nunneries. It is a popular hidden valley ringed by the Boudha Himal and Himal Chuli to the west, Ganesh Himal to the South and Sringi Himal to the north. The altitude of Tsum Valley trek varies from 1905m in Lhokpa to over 5,093m at Ngula Dhojhyang pass on the Tibatan border. The Valley is bounded by three high passes – the Ngula Dhoj Hyang (5,093m) to the west and Yamdro Pass (5,326m.) to the north. Trails are strewn with artistic chortens and lined with mani walls carried with drawings of deities and inscribed with prayers. The Tibetan Buddhist culture is still very prevalent in Tsum and the scenery is just stunning, with beautiful forests and countryside, with Ganesh Himal towering above the valley. The local people are of Tibetan origin and practice Bon religion and speak their own dialect.
Many Trekkers combine the Tsum Valley with the Manaslu Circuit trek, which start from Gorkkha or Arughat and ending in Besisahar. You can catch a jeep further north from Dharapani onwards.
