The Island of Kauai is the oldest island in the Hawaiian chain. Home to Waimea Canyon, the largest canyon in the Pacific, Kauai is filled with dramatic landscapes and gorgeous beaches. Located just to the West of Oahu, Kauai makes a convenient base to take a day trip over to visit Pearl Harbor or attend a luau at the Polynesian Cultural Center. You can even take a trip over to the Big Island of Hawaii to see the volcano.
