While newly established in 2013, this five-day trek traces the route of a far older trail once used to transport salt and silk from the Indian border at Samdrup Jungkhar to the area around Trashigang. Walking from north to south gets most of the serious climbing out of the way early on in the trek, though the trail can be tackled in either direction and at any time of year.
The first part of the rolling trail follows the Khaling Chhu from a lakeside campsite at Cheya Tsho up to the highest point of the trek (2,220m or 7,280ft) at Mongling, from where there are fantastic views of Deothang and Pema Gatshel spreading away below. From Mongling the trail descends steeply to a campsite at Radingphu, then crisscrosses the Duri Chhu to the roadhead at Nelang. From Nelang it is a short drive to Samdrup Jongkhar and the Indian border.
