I'm living in Hoi An and my parents will visit soon. While they are here we will go to Hue by private car, staying there for three days. I was thinking we could travel to Hue via the Hai Van Pass, and come back via Dong Giang to visit the Co Tu people and see a different type of scenery. Is this a good idea? I haven't been to Dong Giang so if anyone has done this, advice would be much appreciated! Thank you.
