Maui, Hawaii

Maui’s Road to Hana winds past 620 curves and 59 bridges, with waterfalls that make mainland national parks look modest, justifying a fourteen-hour flight. The 64.4-km drive takes 2.5 hours without stops, but visitors average 8 hours due to 300-plus water features. It outperforms #3 Bali in scenic density, featuring 10 distinct climate zones within 1,883 square kilometers, a number unmatched by any other Hawaiian island.
