Getting Around Oahu
If you’re planning to stick to Honolulu / Waikiki or stay close to your resort in Ko Olina, then you can skip the rental car. But if you want to explore the island or stay on the North or East Coasts, a rental car is a good idea (at least for the days you plan to venture out).
Renting a car in Waikiki is likely more expensive than the airport but might make sense if you only need it for a day or two.
FYI: Parking in Waikiki is expensive (around $30 - $40 / night).
Turo is like Airbnb but for cars. You can either have the car delivered to you or you can pick it up.
In Honolulu and Waikiki it’s pretty easy to get an Uber or Lyft ride. The rest of the island can sometimes be dicey — especially late at night. We had good luck with scheduling rides — even early morning ones for sunrise hikes.
Oahu’s major cab companies have 24 hour service. Charley’s Taxi Service (877-531-1333) is a good one.
TheBus, Honolulu's bus system is great. The Google Maps app is perfect for navigating the routes. It's $2.75 for a one-way fare and $5.50 for a day pass. (Just make sure you ask for the day pass before you put your money in the cash box).
Biki bikes are all over Waikiki, Ala Moana, and Downtown Honolulu. Just pay at the kiosk with your credit card and return it to another Biki Stop. Download the app to unlock the bike or find bike stops.
In Kailua, Pedego Electric Bikes are like a beach cruiser but with some extra oomph.
You don't need a special license to drive a moped, but you do have to be 18+. They're fun in the city but keep in mind that they don't go fast enough for the interstate. Hawaiian Style Rentals is a good option.
Plenty of limo services to get you to and from the airport, or wherever you'd like to go.
