    Travel tips

    Oahu is the 3rd-largest island in the Hawaiian archipelago, covering an area of about 930 square miles. Hotel shuttle buses, public buses, tour buses, taxis, and ride-sharing apps – Uber and Lyft – are available for getting around the island, although it's most recommended to hire a car. 

    Honolulu is the capital city of the island, home to famous neighbourhoods such as Downtown, Waikiki, Kahala and Manoa. Each can easily be explored on foot. They are home to a good choice of dining, shopping and nightlife entertainment options. For longer distances throughout the city, the Waikiki Trolley also offers a convenient and affordable way to travel between Downtown and Waikiki. 

    Taking a taxi in Oahu

    Hailing a taxi is not the best way to travel around Oahu – it’s rather expensive and not the most efficient mode of transportation, especially in Honolulu’s traffic. Taxicabs can easily be found at the airport, cruise terminals, and be called from any hotel. In addition to the fare, a 15% tip is expected.

    Ride-sharing apps such as Uber and Lyft can also be used throughout the island and the Honolulu International Airport. Rates are slightly cheaper than standard cabs.

    Travelling by bus in Oahu

    “TheBus” is Honolulu’s bus system, featuring over 100 routes and a few thousand stops in Honolulu and around the island. It’s very convenient and is the cheapest way to explore Oahu. 

    There are 1-way tickets as well as 1-day and monthly passes available. The first 2 can be purchased directly on the bus, while monthly passes can be found in various locations, including 7-Eleven Stores. Check out “TheBus” website for further information. 

    Renting a car in Oahu 

    Renting a car is the most popular option for you to discover Oahu at your own pace. Conveniently, a foreign driving license can be used for up to 4 months in the states. Be aware that some rental agencies require drivers to be 25 years of age or older. A surcharge fee may apply for drivers below 25 years old. 

    Rental car agencies can be found at the airport, near the cruise ship terminals, and throughout Honolulu. In a way to save money, it’s recommended to book a car a few weeks before your departure, preferably from a local company. Note that traffic and parking can be an issue in Honolulu.
