A 2-hour drive from Trashigang is Chorten Kora, modeled after Boudhanath stupa in Nepal, where local people and Dakpa people from Arunachal Pradesh (India) gather in February/March for a festival to circumambulate the chorten. A similar festival in Gom Kora takes place 10 days later. Bumdeling to the north is home to wintering black-necked cranes and to Ludlow’s Bhutan Glory, the national butterfly of Bhutan. Important religious sites are found all over the Dzongkhag including Pemaling in the alpine area; Rigsum Gonpa, Dechenphodrang ney and Omba ney (the Taktshang of East Bhutan) between 2000 and 3000m, and Gongza ney and Gom Kora along the Drangme Chhu (800-900m).
