Risk Factor: Elsewhere in China, the Tianmen Shan Big Gate Road (also called the Tianmen Winding Mountain Road) is said to have 99 curves, symbolizing the nine palaces of heaven. But even if you expertly navigate all those swings, you still won't have reached the mountain's summit. There are also 999 stairs to climb before you reach the peak, where Heaven's Gate—a natural rock arch that was believed to be the link between the gods and the mortal world—awaits visitors.
Why you might be tempted to drive it anyway: You don't actually have to drive or do all that stair-stepping to get there. A cable car takes visitors directly to the top. (Shhh, we won't tell).
