With good public transportation and some tourist shuttles, Oahu has more options for moving about than the other islands. The highway system on Oahu is fairly well developed, though a bit crowded. Regular freeways cut across Honolulu, and highways with varying numbers of lanes encircle the island. There are also north-and southbound highways that may pass through mountain tunnels.

Oahu is the one island where you can probably get anywhere you want to by bus. The bus system, known as TheBus, has been highly praised for its routing, efficiency, and price. Bus fare is about $1.75 per ride. The Ala Moana shopping center serves as a major bus hub for Honolulu and you can catch buses in all directions from that location. For more information, visit www.thebus.org.

The Waikiki Trolley operates open-air trolley-buses that will get you to many of Oahu's favorite tourist attractions, including museums, the zoo, aquarium, and shopping centers. A one-day unlimited pass costs $20, and a four-day pass costs $45 (the rates are cheaper for teenagers and children). The Trolley only operates in the vicinity of Honolulu, so it's not really an option for exploring the windward side or North Shore. Take a look at their Web site at www.waikikitrolley.com.

Your Arrival

Getting out of the Honolulu Airport and on with your vacation shouldn't be a difficult thing. If you're on a tour, you'll likely be greeted by company representatives bearing group signs and flower leis. If you're on your own, collect your bags and follow the signs out to ground transportation. Taxis, hotel shuttles, and limos are available. If you rented a car, shuttle buses will take you to the car rental.

The Waikiki Shuttle is available for those staying at a hotel in Waikiki. The shuttle operates around the clock and runs every twenty to thirty minutes. Prices are $8 one-way or $13 round-trip. Children aged three and under are free. There are extra charges for passengers carrying surfboards, golf clubs, and bicycles.
