Legend has it that the revered Buddhist saint, Guru Rimpoche, who spread Tibetan Buddhism throughout the Himalayas, discovered this hidden land over 1700 years ago. This land has been called ‘beyul’ or refuge has been inhabited by Tibetan nomads, called Dok pa, for over a thousand years. It has remained isolated, due to its remote location and has been only open for trekking and tourism since 1989.One of the highest inhabited places on earth, Dolpo is also still a stronghold of the pre-Buddhist, Bon Bo religion. It is a high, mountainous region of fortified villages, ‘dzongs’ known as many high passes. Passing through many ancient monasteries, highland villages and wonderful natural scenery as we make our way to Phoksundo Lake and the fabled Shey Gompa. We explore alpine meadows and exotic villages in Upper Dolpa which has kept Bhodiya culture alive. And also get to experience Thakkali culture in Mustang region. The most interesting factor of this trek is that we get to witness the cultural difference people of different regions had centuries ago. Dolpo is a high mountainous settlements holds to the nomads migrated to the region ages ago. Similarly the people of Mustang also called Lopas also migrated from Tibet almost during the same time. Still the contrast between the people of these two regions in the past and in the recent times is so huge in terms of civilization.
