The Hana Highway, known as the “Paradise Road,” was also named one of the “most beautiful roads in the United States” by National Geographic. There are 620 curves on the whole road, of which more than 500 are 180 degrees of large angles, and 59 bridges, of which 46 are single-lane bridges, which were built in 1910. The first half is more famous, but in fact, the original rainforest in the second half + the seaside unpaved road is more exciting.
