Quite literally, and conveniently, the Hawaii Public Transit system is called TheBus. TheBus is a very convenient way to get around the entire island for a small price.
Oahu Public Transit Adult (Anyone over 17 years old)
One way tickets are inexpensive at $2.50 to any spot on any of the routes. However, that’s one-way. If you got off to walk around or go to the beach and later want to get on and go to a different location or back to your original spot…then that’s another $2.50. Once you get used to the routes and know where you’re going, though, then $2.50 can be a bargain.
If you’re going to be using the public bus on Oahu a lot, or as your primary source of transportation, then the monthly or yearly may be a better option.
$60 Unlimited Monthly usage during a calendar month (Regular and Express)
$660 for Unlimited Yearly usage during the calendar year (Regular and Express)
Children under 5 years old when accompanied by an adult are FREE.
Oahu Public Transit Youth (6 to 17 Years old)
Pretty much it is cut in half.
One way tickets are $1.25
$30.00 for monthly unlimited usage. (Regular and Express)
$330 monthly unlimited usage. (Regular and Express)
Oahu Public Tansit “TheBus” Visitor Fare
Visitors are luck to be able to purchase a 4-day TheBus Pass for unlimited usage of Regular and Express during the 4-day, consecutive period for which the pass was purchased. So, while you can’t visit Oahu for a week and buy a 4 day pass and use it on ANY 4 days that you’re on Oahu, the visitor pass does make it a great way to get around and explore the island.
You can purchase visitor passes for TheBuss at ABC Stores in Waikiki and Ala Moana Center as well as the Kalihi Transit Center (address below)
