The largest eight islands are in order of size in the above table. Those same islands in order of population are Oahu (including the city of Honolulu), Hawaii (often called “The Big Island”), Maui (The Valley Isle), Kauai (The Garden Isle), Molokai, Lanai, Niihau, and the least populated island in Hawaii, Kahoolawe.

Many people confuse the most populated island, Oahu (the third largest island), with the largest island, the Big Island of Hawaii. People who have only been to Honolulu often mistakenly say they have only been to the “big island,” but in fact, the island they went to is Oahu.  The most famous parts of the state of Hawaii, Waikiki Beach, Pearl Harbor, Diamond Head, and the Polynesian Cultural Center, are all on the island of Oahu. More people visit Oahu than any of the other Hawaiian islands because of those sights and because there are more direct flights from the United States and other countries to Oahu than to any of the other islands. But each island is unique, and each island is worth visiting. Be it the mysterious green sand beach on the Big Island or Waimea Canyon (which Mark Twain described as the “Grand Canyon of the Pacific.” on Kauai, or even the Black sand beaches on Maui, no matter which islands you visit, you will find something fascinating to explore.
