The Hải Vân Pass is an approximately 21 km long mountain pass on National Route 1A in Vietnam. It traverses a spur of the larger Annamite Range that juts into the East Sea of Viet Nam, on the border of Đà Nẵng and Thừa Thiên–Huế Province, near Bạch Mã National Park.
The twisting road on the pass has long been a challenge for drivers traveling between the cities of Huế and Đà Nẵng. The pass is renowned for its scenic beauty. Presenter Jeremy Clarkson, host of the BBC motoring programme Top Gear, featured the pass during the show's 2008 Vietnam Special, calling the road "a deserted ribbon of perfection—one of the best coast roads in the world."
