9. Hana Highway – Hawaii

Advertisement
Maui is 84 kilometers long and passes through lush rainforests. With 600 curves and 59 bridges, this narrow, winding coastal route offers a perfect escape from everyday life. Although the drive is long, it offers spectacular views of the northern coastline, rainforests, waterfalls, and black sand beaches. Drivers should be careful on blind curves, but the road is paved all the way and very challenging.
