Trashigang is the largest district in the country and the heart of eastern Bhutan which was once a centre for trade with Tibet. It lies at the foot of the steep wooded valley. Nomadic people living in the higher Himalayas come here to shop and sell their products during winter. It is a good base for excursion to Trashiyangtse, Khaling, Radi and Phongme. It is the junction of the east west highway with road connecting to Samdrup Jongkhar and then to the Indian state of Assam. The Trashigang Dzong built in 1659 serves as the administrative seat for the district and also home of the monk body. It is situated in the steep hill overlooking the river which gives a remarkable view of the surrounding landscape.
