Tashigang is located in the far east corner of the country. It is the country's largest district. Tashigang town, on the hillside above the Gamri Chu, the river, was once the center for a thriving trade with neighboring Tibet in the north. It is the junction of the east-west highway, one of the major arteries of the country, with road connections to Samdrup Jongkhar and then into the northeastern Indian state of Assam. The town is also the primary marketplace for the semi-nomadic people of Merak and Sakteng, who are known for their attractive costumes and their way of dressing up beautifully.
Tashigang Dzong was built in 1659 and serves as the administrative seat for the district as well as the home of the monk body. The dzong commands a remarkable view over the surrounding countryside.
Gom Kora is located approximately 24 kilometers from Tashigang. The temple of Gom Kora is set on a small alluvial plateau overlooking the river. Gom Kora is surrounded by rice fields and clumps of lush banana trees. It resembles an oasis in an arid landscape. It is one of the famous places where Guru Rinpoche meditated in order to subdue a demon which dwelt in a huge black rock.
