About 30% of visitors use The Bus to get around Oahu, according to the state. It really is usually a great, cheap way to get around the island. For $7.50 a day or $80 for a monthly pass, you can’t beat it. Kids between the ages of 6 and 17 ride for only $3.00, and kids 5 and under are free! We recommend downloading DaBus and DaBus 2 apps on your phone; one has the schedule and route information and the other keeps track of reroutes, late buses, and cancellations.
