Explore the beauty of Oahu by car

Word to the wise: To avoid airport surcharges, which can total around 40 percent of a car rental cost, use a rental company located in the city.

Noteworthy for: Beeping your horn in a non-emergency is considered rude on Oahu and watch your drinks; most island fatalities are alcohol related.

While Oahu's public bus system is great, it can be slow, and doesn't service some of Oahu's must-see destinations, like the North Shore. Hiring a car is a great way to explore the island's scenic wonders at your own pace.

All the major US car rental companies serve Honolulu, and inside the airport you'll find Avis, Budget, Dollar, Hertz and National. Rental companies that require a shuttle from the airport include Advantage, Alamo, Enterprise and Thrifty.

Car rental rates are somewhat negotiable, depending on availability. The website Discount Hawaii Car Rental will help you compare and find the best deals on daily or weekly rentals. Keep in mind that during major holidays, prices are higher and vehicles book out fast.
