The Guoliang Tunnel is a road carved on the side and through a mountain for a stretch of 0.78 miles. Located in the Wan Xian Shan Jing Qu national park in China, travelers can see downhill from the windows created in a few places across the tunnel.
Dubbed one of the most dangerous routes in the world, it also offers captivating views of the green mountain range around it. It was opened to traffic in 1977 to access the Guoliang village, which is a breathtaking tourist attraction in its own right. Since then, the road and the settlement at its end have become favorite haunts for film crews.
