Bumthang District (
Dzongkha: བུམ་ཐང་རྫོང་ཁག་;
Wylie:
Bum-thang rzong-khag) is one of the 20
dzongkhag (districts) comprising
Bhutan. It is the most historic dzongkhag if the number of ancient temples and sacred sites is counted. Bumthang consists of the four mountain valleys of Ura, Chumey, Tang and
Choekhor ("Bumthang"), although occasionally the entire district is referred to as Bumthang valley.
