The Nimalung Festival is conducted at Nimalung Lhakhang, situated in Chumey within the Bumthang region. This Tshechu is an annual event, taking place in the 5th month of the Bhutanese calendar. A remarkable highlight is the display of a colossal 9-meter-wide Thongdrol of Guru Rimpoche, which not only evokes awe but is also believed to purify the sins of all who gaze upon it. Throughout the Tshechu, a series of vibrant and mesmerizing mask dances are performed.
