Beguiling and beautiful, the former capital of Vietnam is still revered as a cultural and religious centre, and achieved UNESCO World Heritage status in 1993. The city owes its charm in part to its setting on the Perfume River, but more significantly, to its many ancient temples and palaces – all vestiges of the last remaining Vietnamese dynasty, the Nguyen dynasty. The 19th century Hue Citadel – otherwise known as The Imperial City – should be high on your ‘to-see’ list (you will need a day to get through the entire complex); while scattered along the riverbank are myriad more shrines and stupa, including the Thien Mu Pagoda with its octagonal tower. There are a number of mineral hot springs, boat trips on the river can be organised, and the eateries in town boast a culinary experience you will find only in this region.
