1. North Yungas Road, Bolivia
The North Yungas Road, or “the Road of Death,” is often described as the most dangerous road in the entire world, claiming the lives of an estimated 200 to 300 unlucky travelers every year. This is due to a combination of its narrowness (an average of 10 feet wide at any given point), its lack of guard rails, the extreme dropoffs alongside the road, and its road surface, which is often muddy and rocky. The road leads from La Paz to the Amazon Rainforest, and the temperature difference often contributes to vision-obscuring rain and fog. The road was partially modernized in 2006, adding better drainage, multiple lanes, and guardrails to many places, but it is nonetheless a road that should be approached only with great caution.
