9. Sichuan-Tibet Highway, China
The Sichuan-Tibet Highway is a high-altitude road that stretches over 1,300 miles through some of the most rugged and remote terrain in the world. The road is notorious for landslides, rockfalls, and avalanches, as it passes through the Himalayas. With altitudes exceeding 16,000 feet, the thin air and steep inclines make the drive physically demanding. Weather conditions can change rapidly, adding to the already hazardous journey. The road’s many sharp turns and narrow lanes offer little room for error, making it a true test for drivers seeking a challenge in one of the most awe-inspiring landscapes on earth.
