Bend Road to Heaven, China: In 6.8 miles, how many sharp turns can you make? It turns out 99 of them! In Tianmen Mountain National Park in China, this short stretch is full of drops and turns that are built hundreds of feet in the air. If this road was straight, you could drive it in less than 10 minutes. But 99-Bend Road is one of the most dangerous roads in the world because it is steep, has lots of turns, and has nothing to stop you from falling to your death!
