Hue, a two hour train ride north from Da Nang, is quite the hidden gem in Vietnam. Most people fly into Da Nang and head straight to Hoi An, but skipping out on Hue would be a big loss. As it’s still in the process of developing its tourism sector, there isn’t a large list of things to do in this city, however, the few things Hue has to offer are well worth the trip. Among these is a visit to the Imperial City in Hue: a former walled palace and fortress that was once the capital of Vietnam. Much of the Imperial City is still currently under construction, but you’ll be surrounded by temples and structures, and a rich history throughout.
