We think that renting a car in Hawaii is one of the most important things you can do to get the most out of your vacation. Over 80% of the visitors to the Big Island agree and rent a car during their stay.

The best way to find a good deal on a Hawaiian car rental if to book early, preferably with a local rental agency.

It is possible to make your way around the Big Island using public transport it is both more time efficient and convenient to rent a car.

Most of the National car rental services offer service at any of the two international airports (ITO – Hilo and KOA – Kona) on the Big Island. If you have a clear favorite please go ahead and book with your rental agency of choice. Keep reading if you are willing to shop around to find the best possible deal on your rental car.

1: Find the best deals for Big Island rental cars

The price of a rental car depends on many factors, the most important of which are availability and the time left until picking up the car.

As for the time of booking, you should keep the “usual suspects” in mind when planning your trip: Book early if you are going to be on the Big Island during popular events such as the Ironman triathlon (mid-October) or the Merry Monarch Festival (mid-April). Christmas is also a notorious period if it comes to renting a car.

These points are explained in more detail below.

Go local for low prices

The best way to find a good deal on a Hawaiian car rental if you book beforehand is to look for the local rental agencies. Besides, why not go local?

Some rental agencies here on Hawaii have negotiated guaranteed discounts with the rental car companies, which they pass no to their costumers. You can find especially good rates if you are willing to be flexible about the exact details of the make and model.

The following local booking site offers discount rates on car rentals in the state of Hawai’i. We use them ourselves when we are in need of a rental car, and have never found better rates on or off the Big Island:

1. Discounthawaiicarrental.com (through their new website discount USA car rentals)

Book early and wait for lower prices

If getting the best deal on a rental car is important to you we recommend that you book early at the local rental agency mentioned above. About 6 weeks before your departure is a good time to try again to find a better deal.

It is important to make your first reservation with an agency that allows cancellations without a penalty. At the time of writing, carrentalinhawaii allows this, but it is important to double check this before you make any commitment.

For example, a mid-sized 8 days car rental might cost $450 the first time you book 4 months before you arrive at Hawaii. Typically, this price will start declining down to say $240 at 1 or 2 weeks before arrival. The last days before arrival, prices can suddenly jump up to ridiculous prices again. We have seen examples where a car that was at its lowest $240 suddenly jumped up the $900 in the last days before arrival.

Another website that allows cancellations without penalty is rentalcars.com. (Complete refunds for fully prepaid bookings on cancellations 48 hours or more before your rental is due to start.  This information was last confirmed January 2017 at this URL)

Using this method can thus save you a couple of hundred $$$, but does require that you invest extra time in booking and re-booking. It works best for people that like to plan ahead.

Book early and play the “priceline game”

This method can potentially give you the biggest savings but should be combined with making an early booking in case nothing turns up.

Priceline is a website connects customers and car rental agencies via an online bidding system. You can bid whatever you want on a rental car, and if the rental agency accepts, the deal is ‘locked’.

The advantage of this system are the potentially very low prices. 30% to 40% discounts compared to ‘direct’ booking prices are not uncommon. The disadvantage is that you are paying upfront and that you can not cancel/change/extend your agreement once your bid is accepted. A good rule of thumb is to aim for at least a 30% discount compared to the direct rate to justify this lack of flexibility.

If you use priceline far in advance it is best to start your bidding low because ‘normal’ prices are expected to drop (except around the really busy periods, in which case you should book early), and once you make a deal using priceline it cannot be canceled. Prices generally drop once the rental date approaches, but it is possible you won’t find a good enough deal with priceline. It is important to already have an early booking so that you don’t find yourself without a car on Hawaii.

Priceline works with many of the large car rental agencies such as Hertz (see note 1), Budget, National, Avis and Alamo, and the quality of the cars you rent is equal to the ‘normal’ car rentals. If you want to have a try you can go to the priceline website.

Better prizes for long term car rentals

If you are staying for more than 30 days and want to rent a car on the Big Island, have a look at e.g. island discount rentals. These people rent out more ‘used’ cars and have great prices on longer term rentals.

2: Rental Cars in Hilo

It is easy to pick up a rental car in Hilo if you arrive by airplane or cruise ship.

The following seven rental car companies are represented at the Hilo Airport (last checked June 2017 from source):

• Advantage
• Alamo
• Avis
• Budget
• Dollar
• Hertz
• National

The offices of all these agencies are located on the side of the road opposite to the arrival and departure terminal.

There is no public bus service to or from Hilo airport. If you don’t have a rental car your transport from the airport would have to be either by taxi or personal pick up. Hilo International Airport (ITO) is located on the edge of Hilo, about 3 miles from downtown.

3: Rental Cars in Kona and at the Kona Airport (Koa)

Renting a car in Kailua Kona is easiest directly at the airport. There are check-in counters across the street from baggage claim for all major car rental companies.

You can find more offices of these rental car agencies in Kona at the King Kamehameha hotel or scattered through the resorts on the north Kona / Kohala coast.

You can find more information on what rental car agencies can be found where along the Kona coast (in Kona, at the airport, and at the resorts) below. Afterwards we discuss if you’d need a rental car for your whole stay in Kona.

4: Assorted tips for renting a car on the Big Island (FAQ)

Wow, you made it all the way to the end of our guide. Thank you for your interest!

We have reserved this space to leave our advice on frequently asked questions about renting a car on the Big Island. Please drop us a line if you have any question about renting a car on the Big Island that is not answered on this page.

Can you take your rental car to Mauna Kea?

Most rental agencies do not allow you to take your car onto the really rough roads of Hawaii. In the case of your Hawaiian vacation this is relevant if you want to go stargazing.

The road to the summit of Mauna Kea between the Onizuka Center for International Astronomy and the telescopes on the summit is off limits for most rental cars. Another place you should not visit using a rental car is green sand beach.

If you want to drive up the mountain yourself (instead of joining a tour) you need a 4WD car. The only 4WD rental agency on the island that allows their car to be taken that far up is Harpers Car Rentals. Harpers operates from two locations: one in Hilo and one in Kona.

Consider double booking a 4WD from them for a day in addition to your own rental car since this probably will be your cheapest option.

Do you need a rental car for your whole stay on the Big Island?

If you plan to spend a significant part of your stay at one location and don’t have big travel plans you might be best off renting a car for only a part of your vacation. Keep in mind though that, even if you stay at the resorts close to the beaches, having a car is still really handy to explore those beaches.

If you only need a car a couple of days it would be best to rent a car close to where you are staying. Even if the deals on rentals cars at the non-airport locations available can be less good, it is often not worth the time and effort to find the lowest price if this means extra travel time to pick up and return the car.

If you want to rent a car during your whole stay on the Big Island renting a car directly at the airport is your best option. You save the money and effort you’d otherwise spend on getting to your accommodation from the airport by shuttle, bus or taxi. Last time we checked there was no free airport shuttle from Kona airport to any hotel, so estimate to pay about $50 per person for shuttles to Kohala resorts, and $30 to $35 to Kona.

Don’t get stranded, plan ahead and book early!

On a final note: please be aware that there is a limited supply of rental vehicles on the Big Island we because… we live on an island.

Special events such as the ironman marathon or the merry monarch festival frequently take up all available cars. Call ahead or make an early reservation if you don’t want to be unpleasantly surprised upon arrival.
