The Term “salt trek route” is derived from the purpose it served prior to the construction of the national highway from Trashigang to Samdrup Jongkhar. The people of the Eastern Dzongkhags used to make voyages via this route to take salt and silk from the border town of Samdrup Jongkhar. It is an eight day trek from the day of arrival. This 8 day trek will take you through pristine broadleaved and pine forests with spectacular views of villages and mountains amidst the clouds. Although this Nature-based trek route does not lead into really high altitudes, it is tough and involves long steep descents and ascents.
