The Lhuntse Dzong sits dramatically on a spur above the Kuri Chhu river, visible from a long way off as you come up the valley. Five interior temples and a thriving monastic body make it one of the more active dzongs in eastern Bhutan, despite the small size of the district it administers.
The interior — open to visitors with a guide — has fine murals of Pema Lingpa's lineage and a striking statue of Guru Rinpoche. Outside, walk the kora path around the dzong's base for views down the river and across to the cliffs opposite.
