Sakten valley is situated in eastern Bhutan under Trashigang Dzongkhag at an altitude of 3000 meters. It is inhabited by a semi-nomadic people known as the Brokpas.
Living close to nature in this pristine wilderness, the Brokpas way of life has remained virtually unchanged through the years and they still mainly depend upon yak rearing and animal husbandry for their livelihoods. Sakteng valley remains untouched and unspoiled by the influence of the outside world.
The Sakten Tshechu is held for three days each year at the Sakten Lhakhang situated just next to the village. In addition to its religious function the Tshechu provides the Brokpas with an occasion for revelry and merry making. Like all Tshechus in Bhutan, the festival is a time when the entire community can come together for celebrate and engage in worship. The festival is a lively, colorful and jovial event as the Brokpas are all dressed in their traditional finery and enjoying the celebration with rounds of ara (local wine). The rare Yak dance and the Ache Lhamo dance are performed during this festival. These dances are unique to the Brokpa culture and are quite distinctive from the usual mask dances seen in other parts of the country
