The names of the eight main Hawaiian Islands are Hawaii Island, Oahu, Maui, Kauai, Lanai, Molokai, Kahoolawe and Niihau. Despite the fact that there are eight main islands, there are only four counties in the state. They are Hawaii, Honolulu, Maui and Kauai. Hawaii is the widest state from east to west. It is so wide and remote, in fact, that it has its own time zone.
