I have used several maps of Honolulu and Oahu, but without question this is the best of the bunch. Not only is this map detailed and current, it is logical and complete. There is an overall map of Oahu, and several smaller inset maps of key places including Honolulu, Waikiki, Kaneohe, the Mokapu Peninsula, Laie, and Mamala Bay (including the huge Ala Wai Harbor). The Honolulu map is very detailed and continues far enough to the West to cover the airport and the publicly accessible parts of Pearl Harbor. Note that this map, unlike many others, uses the traditional Hawaiian spellings complete with accents and pronunciation marks, which makes it the ultimate in accuracy, although when comparing it with many more anglicized works, the spellings may differ slightly.
This map is without question the best overall map for navigating the sometimes very convoluted (and busy) roads of Oahu: if I could only take one map to Oahu with me, this would be the one. I highly recommend this map to anyone traveling to Oahu.
