The Dzong sits on a bluff above the Kameng river right in the centre of town. It is not a museum or a ruin — it is a working medieval village, with narrow stone passageways, low doorways, and tightly packed two-storey houses built of river stone and timber. The walls of the old fort itself are largely intact, and you can walk through the original gateway into the lanes beyond.
Wander in quietly. The residents are used to visitors but the Dzong is their home, not an attraction. The view down to the river and across to the terraced fields opposite is one of the best in the valley, especially in late afternoon when the light hits the stonework.
