Hue to Hoi An for 1 day (Top grear tour) (or Hoi An to Hue)

The Hai Van Pass, or "Pass of Ocean Cloud". These mountain once formed a national frontier between Dai Viet and Champa, and Hai Van ‘s continuing strategic importance is marked by a succession of forts, pill-boxes and ridge-line defensive walls erected by Nguyen dynasty Vietnamese, French, Japanese and American forces. From the top there are superb view, weather permitting, south over the sweeping curve of Da Nang Bay, with glimpses of the rail lines looping and tunneling along the cliff.
