Getting around
Sixty bus routes, collectively named TheBus, cover the whole of Oahu ( 
808/848-5555, 
www.thebus.org ). All journeys, however long, cost $2, with free transfers onto any connecting route; a 4-day pass costs $20. The most popular routes with Waikiki-based tourists are #2 to downtown, #8 to Ala Moana Shopping Center, #20 to Pearl Harbor, #22 to Hanauma Bay, and the bargain "Circle Island" buses (#52 clockwise and #55 counterclockwise), which take four hours to loop around the central valley and the east coast, passing the legendary North Shore surf spots.
Among companies running city and island bus tours, for anything from $27 up to $78 for a full day, as well as off-island packages, are Polynesian Adventure Tours ( 808/833-3000 or 1-800/622-3011, www.polyad.com ).
