Tianmen Mountain road, Zhangjiajie, China
Its an 11 km road with 99 bends that reaches the top of Tianmen Mountain and takes visitors to Tianmen cave, a natural hole in the mountain at a height of 131.5 meters.
The highest point of the road is 1.300m above sea level, and the lowest point is 200m. The road took eight years to finish with work starting in 1998, and finishing in 2006.
The driver should be extra careful during the drive. Taking it slow and paying attention to every curve and turn. Not being overly careful could make it too easy to junk a car, or worse injure and even kill passengers. All too many have seen this unsettling fate.
