This is probably the most beautiful royal tombs of the Nguyen's Dynasty Kings and it's really majestic and magnificent. But you will need to climb flights of steps, totaling hundreds of them, one after another in order to reach the main exhibition halls. It's quite a challenge walking up (same too while walking down as the steps were steep with no handle at the side for support). But from here, you will enjoy a great "top-down" view of the surrounding areas.
The exhibits were grand and nice and if you are into anthropology or a fan of Vietnam's history, this place is a must visit for you as you will get to see "up and closed" various exhibits, photos, paintings of the past. For me, I found the place cultural rich and got to know more about the history of Vietnam during the past dynasties, that's eye opening experience for me.
And if you prefer not to walk up, you can rest at the coffeeshop located about 200m from the main entrance, where visitors will get a drink or fingerfood and used their washrooms.
