Hawaii Public Transportation
Oahu's public transportation system has a nice website with detailed information on routes and schedules, fares and passes and popular attractions along their routes.
Hele-On Bus (Big Island)
The Hawaii County Mass Transit Agency provides public transportation around the island on the Hele-On bus. In addition, the Transit Agency offers a Shared Ride Taxi program which provides door to door transportation for as little as $2.00 within the urbanized area of Hilo.
The Kaua'i Bus operates a Public (Fixed Route) bus service and a Paratransit (Door-to-Door) bus service from Hanalei to Kekaha daily except on Sundays. The Kauai Bus now provides service to the Airport and limited service to Koloa and Poipu.
Maui Public Bus Transit System
Maui now has a limited public transportation system. The County's website has a complete schedule of routes and times of operation.
