Bumthang Dzongkhag consists of four main valleys, Ura, Chumey, Tang and Choekhor. Choekhor is the largest of the four and is widely considered as ‘Bumthang Valley’. The valleys are broad and gentle carved by the ancient glaciers. The wide and scenic valleys draws a large number of tourists each year. This dzongkhag is one of the most richly endowed districts in terms of historical and spiritual legacy. Some of Bhutan’s oldest and most venerated temples are found in Bumthang, including Jambey Lhakhang. According to legend this ancient temple was built by the Tibetan king Songtsen Gampo in 659 A.D. as part of a chain of 108 simultaneously constructed temples in order to subdue an evil demoness that lay over the Himalayan region. It is the oldest lhakhang in Bhutan. There are numerous other temples and shrines worth visiting in Bumthang and many of them are linked to Guru Rinpoche’s visit in 746 A.D.
