3. Skippers Canyon Road, New Zealand
New Zealand is famous for its scenic drives, but Skippers Canyon Road is a route reserved only for the bold. This narrow, winding road was built during the gold rush in the late 19th century, and much of it remains unchanged today. With its tight turns, steep drop-offs, and loose gravel, driving here requires extreme caution. Rental car insurance often doesn’t cover this road, as the risk of accidents is incredibly high. However, for those who dare, the stunning vistas of the Shotover River and the surrounding mountains make the drive unforgettable.
