World's Scariest Roads

Guoliang Tunnel Road, China

Location: China’s Taihang Mountains

Fear factor: Let’s just say its name translates to the “Road that does not tolerate any mistakes.” In 1972, villagers in a remote area of the Taihang Mountains chiseled a 3/4-mile-long tunnel through a mountain for access to the outside world. Today, the route—15 feet high and 12 feet wide—is a tight squeeze for vehicles, twisting past the tunnel’s 30 “windows,” which provide views off the precipice to a tumbling abyss hundreds of feet below.
