Located in the scenic south-east of Bhutan, the border town of Samdrup Jongkhar is the eastern overland gateway to Bhutan, and holds the distinct honour of being the oldest township in the country. From here you can reach the nearest airport at Guwahati in the Indian state of Assam, from where you can fly to Delhi or Kolkata. It is by far the largest urban centre in eastern Bhutan, and a convenient exit town for visitors who have travelled from the west to the east of the country. Today the road from Trashigang to Samdrup Jongkhar, completed in the 1960s, connects the eastern and southern regions of the country, allowing them to benefit from trade, especially through trade across the Indian border. It lies at elevations ranging from 200m to 3,500m.
