Crossing Hawaii’s Big Island from the east coast to the west is a journey that mixes scenic beauty with practical planning. Whether you’re catching a flight between two airports, driving across lava fields and rainforests, or combining transit options for a more economical approach, this guide lays out the best strategies to travel from Hilo to KOA with clear, actionable insights. We’ll compare speed, cost, and convenience, highlight must-see stops along the way, and provide practical tips to help you design a smooth cross-island itinerary that fits your dates and budget.
Overview: Your best options to travel from Hilo to Kona International Airport (KOA)
Two primary paths connect Hilo and Kona: flying the short inter-island hop, or driving across the island via one of several routes. Flying is fastest and minimizes time on the road, while a road trip delivers iconic coastal and volcanic scenery and can be a memorable part of your Big Island adventure. For travelers who want maximum flexibility, a hybrid approach—partial driving with occasional flights—can also work well. Regardless of method, plan for variable island weather, road conditions, and flight schedules, especially during peak travel times or volcanic activity advisories.
KOA sits on the western side of the island, serving as a convenient gateway to the Kona coast, world-class beaches, and volcanic landscapes. Hilo International Airport, on the island’s eastern side, offers a different flavor of Hawaii—lush rainforests, waterfalls, and a gateway to volcanoes. Your choice will shape your itinerary, the number of signposted stops you’ll enjoy, and how you allocate time for activities on both sides of the island.
Fly from Hilo to Kona: fast, convenient, and hassle-free
Inter-island flights between Hilo and Kona are typically the quickest way to move between the island’s two main hubs. Short hops take you from one side to the other in well under an hour of airtime, with additional time needed for airport security, baggage handling, and ground transportation to your next destination.
Direct flights, airlines, and typical durations
Direct connections between Hilo International Airport and Kona International Airport are offered by carriers that specialize in inter-island travel. Typical flight times range from about 40 to 55 minutes. Several factors influence schedule and duration, including weather patterns over the island and air traffic. While inter-island flights are short, they significantly cut down overall travel time when compared with a loop around the island’s perimeter.
- Flight duration: roughly 45 minutes in airtime
- Common carriers: inter-island specialists frequently operate these routes
- Check-in tips: arrive at the airport 1 hour before departure for domestic-style security and bag drop
Tips for saving money and finding the best times to book
To maximize value when booking inter-island hops, consider the following strategies:
- Book in advance for peak seasons (summer, holidays) and look for midweek departures.
- Be flexible with times; early morning or late afternoon flights can be cheaper and less crowded.
- Set fare alerts and compare bundled options that include carry-on and checked bags to avoid surprise fees.
- Consider a multi-city or round-trip approach if your itinerary includes several island activities.
What to expect at Hilo and Kona airports
Both Hilo and Kona airports are compact, user-friendly gateways designed for efficient inter-island travel. Expect straightforward security lines, rental car counters, ground transportation options, and snack/coffee spots. Because these are smaller hubs, gate changes and boarding calls are usually quick, and luggage processing is generally smooth. If you have a lot of gear for water-based activities, plan a little extra time for baggage handling and ride arrangements to your accommodation.
Drive across the island: three cross-island routes from Hilo to Kona
Driving between the east and west coasts offers a memorable peek at Hawaii’s volcanic landscapes, rainforests, and coastal scenery. There are three established cross-island options, each with its own flavor, driving times, and best photo stops.
Central route via Saddle Road: what you need to know
The central route follows the Daniel K. Inouye Highway, commonly referred to as Saddle Road, which traverses the island from east to west. This option provides the shortest overall driving distance between Hilo and Kona and typically offers the most predictable travel times. The route climbs through high desert and volcanic terrain before dropping down toward the lava plains near Kailua-Kona. Expect highway conditions that are generally smooth, with occasional weather-impacted sections during rain or fog. Plan for roughly 2.5 to 3.5 hours of driving time, depending on traffic and stops.
- Pros: fastest cross-island option, consistent highway conditions, straightforward navigation
- Cons: higher altitude viewpoints may require a light jacket, occasional weather closures due to heavy rain
Northern route along the coast: scenery, stops, and driving times
The northern coastal route hugs the coast from Hilo around through Honoka‘a and Kamuela, offering lush cliffs, black sand beaches, and scenic overlooks. This drive is longer than the Saddle Road option but rewards you with dramatic panoramic views and a slew of photo opportunities. Driving times vary with sightseeing pace; typical durations from Hilo to Kona along this coastal corridor range from about 3.5 to 5 hours, depending on stops and traffic.
- Key stops: Akaka Falls State Park, Waipiʻo Valley viewpoints, historic Honokaʻa town, and scenic overlooks along the northern shore
- Best for: travelers who want dramatic scenery and social media-worthy photos
Southern route along the coast: highlights and practical considerations
The southern coastal route travels along the island’s southern shoreline, offering a mix of lava fields, black sand beaches, and windward rainforests. It’s a longer drive compared with Saddle Road but provides a unique perspective on the island’s southern lava plains and coastal communities. Expect driving times roughly in the 3.5 to 5.5 hour range, depending on traffic and how many stops you make.
- Highlights: Green Sand Beach at Ka Lae, Punaluʻu Black Sand Beach, and sheltered bays along the coast
- Practical notes: some segments have winding roads; allow extra time for scenic detours and parking at popular stops
Which route to choose and expected driving times
Your choice depends on your priorities. If speed is paramount, Saddle Road wins. If you value dramatic landscapes and photo stops, the northern or southern coastal routes are more rewarding. Most travelers allocate 3 to 5 hours for the drive itself, plus additional time for sightseeing, meals, and parking. Always check current road conditions and weather forecasts before departure, as volcanic plumes, heavy rain, or construction can alter travel times.
Top scenic stops on each route
Across all routes, you’ll find a mix of lava fields, waterfalls, and panoramic vistas. Consider these standout stops:
- Central route: views from the Saddle Road corridors, overlook points near the highlands
- Northern route: Akaka Falls, Waipiʻo Valley Lookout, traditional ranchlands
- Southern route: Ka Lae (South Point), Punaluʻu Beach, coastal lava tubes
Public transit and alternatives
Public transportation on the Big Island primarily serves local connectivity within each side of the island. Crossing from Hilo to Kona via bus is feasible but can be time-intensive and require multiple legs. For travelers seeking a balance of cost and convenience, a combination of bus rides with rideshare or a rental car for the cross-island leg often makes the most sense.
Hele-On bus options for crossing the island
The Hele-On network covers East Hawaii and parts of West Hawaii, with routes that can bridge shorter legs of a cross-island trip. There is no single direct cross-island line that mirrors a simple door-to-door service, so completing the journey by bus typically requires planned transfers and longer travel times. If your schedule is flexible and you enjoy sightseeing along the way, a multi-bus itinerary can be a budget-friendly option.
Combining buses with rideshare or rental cars
Many travelers optimize cost and time by using a hybrid approach. For example, you can take a bus to a central transfer point and then finish the trip with a rideshare or a rental car. Alternatively, you can rent a car in Hilo, drive part of the way to a scenic stop, then park and continue with rideshare for a portion if traffic or parking becomes challenging near popular viewpoints.
Planning tips for a smooth cross-island trip
Preparation is key to a seamless cross-island journey. The island’s climate can vary dramatically from east to south and might affect both driving and flying plans.
Road conditions, weather, and safety tips
Before departure, check Hawaii traffic and weather updates for any road closures or delays. Saddle Road can experience high winds and rain at higher elevations; coastal routes may have slick conditions after rain. Always carry water, a small first-aid kit, and a phone charger. If you’re unfamiliar with mountain driving or windy coastal roads, allow extra time and take breaks at scenic pull-outs to rest and enjoy the views.
Cross-island car rentals and return options
Cross-island car rentals are widely available, but some agencies may impose one-way drop charges or limited cross-island mileage. If you plan to fly after driving, verify that your rental agreement permits a cross-island return to KOA or to a different location, and whether additional fees apply for one-way rentals. Consider a plan that aligns with your itinerary to avoid backtracking costs or extra drive time.

Frequently asked questions
Can you drive directly from Hilo to KOA?
Yes. There are a few cross-island driving options, with Saddle Road offering the fastest link between the east and west shores. Coastal routes provide scenery and photo opportunities, but they take longer. If you’re traveling with tight connections, the drive option requires careful planning for fuel, rest stops, and potential weather delays.
Is flying the fastest option?
For most travelers, yes. A quick inter-island flight typically beats a full island drive when you’re racing against a tight schedule. It also reduces wear-and-tear on your vehicle and provides a predictable arrival window for onward plans in Kona.
Are there direct shuttles between Hilo and KOA?
Direct shuttles between Hilo and KOA are uncommon due to the islands’ dispersed populations and airport layouts. The most time-efficient options usually involve a flight or a car rental with a cross-island drive. Some private transfer services may arrange door-to-door options, but these require advance booking and come at a higher cost.
Is it better to stay in Kona or Hilo if you fly in or out?
Choosing where to stay depends on your priorities. If you want quick access to KOA for a morning departure, Kona is convenient. If your plans skew toward hiking, waterfalls, and volcanic landscapes on the east side, Hilo is a natural base. Many travelers split their stay between both sides to maximize experiences and minimize backtracking.
Can you do a day trip from Kona to Hilo?
Technically possible via a flight or a long drive, but a day trip requires careful scheduling. Plan for early departures, minimal time at each site, and a willingness to limit activities to avoid rushing. For most travelers, a two-day stay with a split-base approach yields a more enjoyable experience.
Conclusion: Choosing the best cross-island option for your Big Island itinerary
Whether you prioritize speed, scenery, or price, cross-island travel on the Big Island offers practical options tailored to diverse plans. A quick inter-island flight between Hilo and KOA is ideal for time-pressed schedules, whereas a mid-length coastal or central drive provides the chance to savor Hawaii’s volcanic landscapes, tropical rainforests, and coastal communities. For travelers with flexible dates or larger groups, a blended approach—part driving, part flying—often delivers the best of both worlds. Whichever path you choose, thoughtful planning, awareness of weather and road conditions, and a readiness to adapt will help you maximize the magic of the island.
