The road from Mongar passes the Yadi loops. For five miles the road creates figures of eight as it descend to the valley floor. Arriving in Trashigang is momentous as it marks the end of a 547 kilometer drive from Thimphu. The town, also high up on a mountain, is mostly bustling with activity because of its proximity to Samdrup Jongkhar in the south, which has enabled it to grow as a center of commerce.
Trashigang is used as the market place for the hill people from Merak Sakten who are remarkable for their exceptional features and for their costume, which is brightly colored and different from customary Bhutanese clothing.
The 17th Century Dzong is built on top of a cliff on the edge of town. The views from the courtyard of the Dzong are wonderful. It is obvious to see why the Dzong was considered to be invincible for the invading armies. Until the recent opening of an administrative center in the Dzong at Trashi Yangtse, Trashigang was the center of all religious and secular activity for the region.
