Zhemgang District share its borders with Sarpang, Trongsa, Bumthang, Mongar and Samdrup Jongkhar. It also connects with the border of Assam, India.
The dominant language in Zhemgang is Khengkha. Khengkha speakers historically maintained close contact with Kurtöpkha, Nupbikha, and Bumthangkha speakers to the north. The close contact has classified Khengkha and other languages as part of the Bumthang language group. By all accounts, the Kheng is more closely related to the people of central Bhutan than they are to their neighbors in eastern Bhutan, who are primarily Sharchops.
Most of Zhemgang District is part of the protected areas of Bhutan. Zhemgang’s environmentally protected areas include Jigme Singye Wangchuck National Park and Royal Manas National Park. These parks connect to Phrumsengla National Park in the north via a biological corridor that bisects Zhemgang.
