Crossing over a spur in the Truong Son mountain range, it lies 500 m above sea level.
The 25-kilometer-long pass is popular among thrill-seeking motorcyclists due to its winding roads, sudden curves and blind corners.

Travel bloggers have described the road as a ribbon crossing heaven and earth.
Lying below the pass is Lang Co Bay, which became famous after being recognized as one of the world’s most beautiful in 2009 by Germany’s World Bays.
In 2015 British broadsheet The Guardian named Hai Van Pass among the world's 10 most beautiful coastal roads.
