Hue

 One of Vietnam's most historic towns, Hue is packed to the brim with relics from the reign of the 19th-century Nguyen emperors.

Sitting along the banks of the gorgeous Perfume River, the Imperial Enclosure is a huge site set within walls that sprawl for 2.5 kilometers.

While touring the grounds check out the gorgeous Ngo Mon Gate, the Thai Hoa Palace with its finely lacquered interior detailing, the Dien Tho Residence where the Queen Mothers would live, and the Halls of Mandarins with its preserved ceiling murals.

A dazzling number of historic sites lie outside the Imperial Enclosure walls as well.

One of the nicest ways of visiting a collection of outlying sites is by taking a riverboat cruise on the Perfume River. A day cruise can take you to visit several royal tombs along with some pagodas.

If you're short on time, the best tomb to visit is the Tomb of Tu Doc and the most important pagoda in the area is the Thien Mu Pagoda, with its tower that soars for 21 meters high.
