Hanauma Bay parking lot is fairly small with only 300 stalls and fills up early, normally by 7:00 or 7:30 am, and once it’s full they put up a “LOT FULL” sign at the entrance to the park. Security prevents the public from entering until they have available space. At this point, your only option is to drive around and keep checking back every 15-30 minutes.
If you plan to drive out on your own – arrive EARLY
