I took the train from Danang to Hue, which was cheap and comfortable with a very beautiful route along the coast, but I think I would have preferred going by motorbike over the famous Hai Van Pass. Both for the view and to have the opportunity to stop for photos.
The former imperial seat and national capital from 1802 until 1945 when the emperor abdicated and the capital was moved to Hanoi, Hue is dominated by the enormous Citadel and Imperial City, full of palaces and shrines. The Perfume River and its riverside pedestrian walkway near the Imperial City is very popular with both tourists and locals, and the myriad of dragon-adorned tourist boats are testament to this.
