This was Bhutan’s capital for three hundred years, and the monastic body still moves here each winter for the warmth. The valley is subtropical by Bhutanese standards: rice terraces stepping down to the water, bougainvillea against whitewash, and jacaranda turning the dzong lavender each May.
It pairs naturally with Thimphu and Paro to make the classic western circuit, and it is the gentlest place in the kingdom to simply be warm and unhurried.
Most guests arrive from Thimphu over Dochula, where on clear mornings the eastern Himalaya line up along the pass, so leave early. The valley stays warm when Thimphu is cold, which makes October to April the best time. Spring brings the Punakha Drubchen and tshechu, and summer is hot, green and wet. Two nights is enough to see the dzong, the bridge and the temple walk without rushing.
