Kauai is the most northwestern of Hawaii's major islands and is the 4th largest by size and population. Nicknamed the Garden Island, it is covered with lush greenery and tropical plants, watered regularly by abundant rainfall. As the oldest of the islands, it has been changed the most by the forces of erosion, and this has resulted in natural wonders such as Waimea Canyon and the Na Pali Coast. As a consequence of its age, Kauai also has more miles of sandy coastline than the other Hawaiian islands.
