Hue Ancient Capital is clustered around the Perfume River, which splits the capital of the Nguyễn Dynasty in two. There are endless must-see historic sites, especially those that are UNESCO World Heritage designated. Sightseeing can include the ornate Imperial Citadel, colorful Thanh Toan Bridge, royal tombs and the Forbidden Purple City. Spend a moment in quiet contemplation if you visit Hue Jungle Crevice, where thousands of citizens were pushed to their deaths. Stay there at least 2 nights to explore the happy city.
