Apart from Punakha Dzong, what makes Punakha a pop­u­lar tourist attrac­tion is the Punakha sus­pen­sion bridge. It is built over the Po Chhu riv­er. It is one of the longest sus­pen­sion bridges in Bhutan, span­ning 160 m. It con­nects Punakha town with Punakha Dzong. Draped with prayer flags, it is a delight for pho­tog­ra­phers. Walk­ing on it will by far be one of your most adven­tur­ous expe­ri­ences. Make sure to stop by here.
