9. Kauai, Hawaii
The oldest island in the Hawaiian chain is also regarded as the Garden Isle because of its lush green forest cover. The island also has stunning waterfalls and an equally impressive coastline dotted with beautiful beaches. The blue seas around the island are populated by exotic tropical fishes as well as turtles and coral reefs. Kauai is more laid back than nearby islands and has a more rural look than resplendent – in fact some regions can only be explored by foot.
