Perhaps you weren’t expecting to see a fire-breathing dragon on your vacation, but that’s exactly what you’ll get in Da Nang. Opened in 2013, the six-lane, 666-meter-long (2,185-foot-long), dragon-shaped bridge breathes fire and spouts plumes of water. Visit on weekend evenings (at 9 p.m.) to witness the pyrotechnic display in action; otherwise, take a boat tour for a closer look at this magnificent feat of engineering.
