Khai Dinh is the last of the Nguyen emperors to be burried in Hue, only Bao Dai rest outside of Vietnam.
It is very different than most of the other graves, as it is relatively small, and the architecture has some European influence, hench Khai Dinhs studies in Europe.
The toms itself require climbing lots of stairs, could be heavy on a very hot day, but the reward awaits you at the top: a mosaic Chamber, several items from his period as emperor, lot of Pictures from his funeral, as well as a stunning view over hills, jungle and rice paddies.
Together With a visit to Ming Mang and Tu Duc; a must when visiting Hue.
