Hue
One of Vietnam’s most historic towns, Hue was once the capital of imperial Vietnam, and much of its rich history still remains. Sitting along the banks of the gorgeous Sông Hương (Perfume River), the centerpiece is the Citadel and the enclosed Imperial City. Much of it was destroyed by American bombers during the war, but plenty remains to give you an idea of the former splendor.
A dazzling number of historic sites lie outside the Imperial Enclosure walls as well. Huế is also famous for its spicy cuisine, so be sure to check some local versions of popular Vietnamese dishes.
