The gate way to Eastern Bhutan, Samdrup Jongkhar is situated in the south eastern part and shares borders with the Indian state of Assam. It is by far the largest urban centre in eastern Bhutan. It lies at elevations ranging from 200m to 3,500m. In the earlier past, many British Political Officers stationed in Sikkim took the rote from Samdrup Jongkhar to enter into Bhutan. Historically it was administered by the Gyadrung stationed at Dewangiri. Today the road from Trashigang to Samdrup Jongkhar, completed in the 1960s, enables the eastern half of the country to access and benefit from trade with the south as well as across the Indian border as in the past where it was the main trading centre for the Bhutanese. Samdrup Jongkhar is a convenient exit town for tourists who have arranged to visit the neighboring Indian state of Assam.
The three storied Zangdopelri in the heart of the town serves the spiritual needs of the locals. One may come across intricate frescos and statutes, work of the Bhutanese master craftsmen.
Along the highway enroute to Samdrup Jongkhar, above the town of Dewathang, in Orong one will come across the only Mithun breeding farm in the east. The Mithuns are considered the best breed in Bhutan and it will be worthwhile to stop for a while and take photographs of these magnificent animals. The Mithuns raised here are supplied to the farmers of the six eastern districts.
The Dzong that serves as the administrative centre of the district is one of the newest dzongs to have been built in the country. Unlike other dzongs that are built on strategic locations, the dzong in Samdrup Jongkhar is built on a sprawling ground.
