The road to Hana is an experience in and of itself. After a 17-hour flight I will be taking this 2-hour plus amusement park ride down the road that encompasses 620 hairpin curves through tropical rainforest. In daylight the scenery is beautiful. At night the trip is nauseating! Though only 68-miles the curves and bridges that loop back on themselves at 90 degree angles, makes it seem like the longest journey of your life.
