How long does it take to drive across oahu?
Your question is not real specific, so it is hard to answer well. I’ll give you some possibilities, assuming non rush hour, no traffic accidents, & not stopping anywhere to get a snack or take photos: East to West (Hawaii Kai to Kapolei) just a bit over an hour North to South (Honolulu to Haleiwa) just a bit under an hour and a half Circle Island (over the Pali, along the windward coast to north shore, then down through central Oahu) probably about 3 1/2 hours, but no one drives this w/o stoppping up at the north shore to check out the surf or getting a shave ice at Matsumotos. If you are doing the circle island drive, give yourself a full day to enjoy your trip.
