7Karakoram Highway, Pakistan/China

The Karakoram Highway, which connects Pakistan and China, is one of the highest paved roads in the world, reaching altitudes of over 15,000 feet. This engineering marvel is often referred to as the “Eighth Wonder of the World,” but it’s also one of the most dangerous. Landslides, avalanches, and extreme weather conditions are common, and the road’s high altitude can cause altitude sickness for unacclimatized travelers. The Karakoram Highway winds through the Himalayas and Karakoram mountain ranges, offering spectacular scenery but also posing serious risks to drivers navigating its steep and narrow passages.
