Getting around by bus is an affordable option on Oahu, particularly in the most heavily touristed areas of Waikiki. In addition to TheBus and the Waikiki Trolley, Waikiki has brightly painted private buses, many of them free, that shuttle you to such commercial attractions as dinner cruises, garment factories, and the like.

You can travel around the island or just down Kalakaua Avenue for $2.50 on Honolulu's municipal transportation system, affectionately known as TheBus. It's one of the island's best bargains. Buses make stops in Waikiki every 10 to 15 minutes to take passengers to nearby shopping areas.

You're entitled to one free transfer, so ask for one when boarding. Exact change is required, and dollar bills are accepted. A four-day pass for visitors costs $35 and is available at ABC convenience stores in Waikiki and in the Ala Moana Shopping Center. Monthly passes cost $60.

The company's website has timetables, route maps, and real-time bus tracking, or you can download the free DaBus app for your smartphone. You also can find privately published booklets at most drugstores and other convenience outlets. The important route numbers for Waikiki are 2, 8, 13,19, 20, and 42. If you venture farther afield, you can always travel back on one of these buses.

The Waikiki Trolley has three lines and dozens of stops that allow you to plan your own itinerary while riding on brass-trimmed, open-air buses that look like trolleys. The Historic Honolulu Sightseeing Tour (Red Line) travels between Waikiki and downtown Honolulu and includes stops at Aloha Tower, Ala Moana Shopping Center, and the State Capitol and Iolani Palace. The Waikiki/Ala Moana Shopping Shuttle (Pink Line) runs from the DFS Galleria Waikiki to Ala Moana and back, stopping at various Waikiki locations. The Scenic Diamond Head Sightseeing Tour runs through Waikiki and down around Diamond Head. A one-day pass costs $18 to $32, four-day passes are $54, and seven-day passes are $59. There are often money-saving online deals.
