How to Get Around Hawaii Without a Car
The Honest Answer: It Depends on the Island
Getting around Hawaii without renting a car is genuinely possible on one island and genuinely difficult on the others. Oahu is the exception; Kauai, Maui, and the Big Island essentially require a car unless you are willing to seriously limit what you see and do. Here is the breakdown by island.
Oahu: The One Island Where No Car Works
Oahu has real public transit infrastructure. TheBus (thebus.org) covers the entire island — Haleiwa on the North Shore, Kailua on the windward side, and every Honolulu neighborhood — for $3 per ride. A monthly pass is $80; a one-day pass is $7.50. The buses run frequently in Honolulu and Waikiki, less frequently in outer areas. Route 60 goes to Haleiwa; Route 57 to Kailua. The app for trip planning is DaBus2.
Biki bikeshare has 130 stations across Honolulu, Waikiki, Kakaako, and Kailua. A 300-minute day pass is $20 and covers most inner-Honolulu riding. For Waikiki to Diamond Head, Ala Moana, and Chinatown, Biki is faster than a car in traffic.
What you genuinely cannot do without a car on Oahu: some trailheads (Koko Crater, Makapu'u) have no transit service. But you can Lyft/Uber to those; rideshare is widely available on Oahu.
Maui: Possible But Limiting
Maui Bus (mauicounty.gov/bus) exists and covers the main corridors: Kahului, Lahaina, Kihei, and Paia. Fares are $2 per ride. However, the Road to Hana has no bus service. Haleakala has no public transit. Most North Shore beaches have no bus. If your itinerary is entirely Wailea resort + Lahaina + Ka'anapali, a bus plus a taxi/rideshare strategy works. If you want Hana, Haleakala, or the north coast, you need a car.
Kauai: Very Difficult Without a Car
Kauai Bus runs between Lihue, Kapaa, and Poipu. It does not serve Hanalei or the North Shore. It does not serve Waimea Canyon. Coverage hours are limited. Rideshare availability on Kauai is inconsistent outside Lihue. If you are staying in a Poipu resort and plan to beach-sit for a week, you might manage. If you want to see anything that makes Kauai worth visiting, rent a car.
Big Island: A Car Is Not Optional
The Big Island's transit system (heleonbus.org) covers some routes between Hilo, Kona, and Waimea, but the frequency is low and most key destinations — Hawaii Volcanoes National Park, Waipio Valley, Pololu Lookout, the Kohala resort strip — are not served. Hilo to Kona is 95 miles via Saddle Road. There is no practical way to visit the volcano from Kona without a car or an expensive tour.
Tour Operators as a Car Alternative
On every island, organized tours can substitute for a rental car for specific activities. Roberts Hawaii and Polynesian Adventure Tours run guided day trips to Volcanoes National Park, the Road to Hana, Waimea Canyon, and more. Rates typically run $90–$150 per person. If you are visiting for five days and only have two activity-heavy days, booking two full-day tours and staying near a resort for the rest is financially comparable to a rental car for the week and requires no driving.
Rideshare Reality in Hawaii
Uber and Lyft operate on all major islands but availability varies enormously. In Waikiki, you get a car in 4 minutes. In Hanalei (Kauai's North Shore), you may wait 45 minutes or get no driver at all. On the Big Island outside of Kona town, rideshare is unreliable. Do not plan your trip around rideshare availability on the neighbor islands unless you have a backup.
Bottom Line
- Oahu: No car needed, transit is real and functional.
- Maui: No car works only if you stay in resort corridors and take tours for everything else.
- Kauai: Rent a car. There is no reasonable workaround for seeing the island.
- Big Island: Rent a car. Full stop.
