Route options at a glance: Central Saddle Road, Northern Highway 19, and Southern Highway 11
Three main artery routes connect Kona to Hilo. Each offers a distinct island flavor and sets the tempo for your day or multi-day trip.
- Central Route — the Saddle Road corridor (now part of the Daniel K. Inouye Highway): a high-altitude crossing through the island’s central plateau, linking Kona and Hilo with expansive skies, volcanic scenery, and quick access to Waimea.
- Northern Route — Highway 19 along the Hamakua Coast: a coast-hugging route with sea cliffs, lush valleys, and dramatic lookout points, including historic towns and waterfalls along the way.
- Southern Route — Highway 11 along the coastline: a longer coastal drive weaving through coffee country, cultural sites, and entry to Hawaii Volcanoes National Park for lava-lands exploration.
Central Route overview (Saddle Road)
The central corridor cuts across the island’s heart, placing you above the clouds for stretches of the drive. Expect cooler air, sweeping panoramas of Mauna Kea and Mauna Loa, and a straightforward cross-island link that minimizes backtracking. This route shines for efficient travel with a handful of scenic detours into Waimea and surrounding highland landscapes.
Northern Route overview (Highway 19)
Running along the Hamakua coast, this route treats you to dramatic sea cliffs, dense rainforest canyons, and viewpoints over the Pacific. It’s ideal for nature lovers and photographers who want coastal panoramas blended with lush inland scenery. Expect a winding drive with several notable pull-offs to stretch and take in the views.
Southern Route overview (Highway 11)
The southern path travels the island’s warm, sunlit belt, passing through coffee country and iconic cultural sites before meeting the volcanic landscapes that define Hawaii’s Big Island. This route is excellent for a longer day that culminates in volcanic wonders and a taste of Hawaii’s agricultural heritage.
Getting there and getting around the Big Island
Arriving and navigating between towns is straightforward, but a little planning saves time and reduces surprises. Below are practical considerations to keep your trip smooth and enjoyable.
Car rentals on the Big Island: tips for smooth sailing
Choosing the right rental is key to a stress-free trip. Consider the following:
- Vehicle type: A comfortable sedan works for most days, but if you plan multiple scenic hikes or need extra cargo space, a compact SUV or crossover offers flexibility on rougher roads and in variable weather.
- Insurance and coverage: Review options and understand what’s covered for road hazards, wind, and gravel—especially on rural routes or parklands.
- Fuel and mileage: Gas stations are plentiful along main routes; plan for longer stretches between towns when you venture into the central highlands.
- Fuel policy: Full-to-full is common—return the vehicle with a full tank to avoid extra charges.
- Pickup and drop-off logistics: If your plan spans both Kona and Hilo, check cross-island return policies and any fees.
One-way rentals Kona to Hilo: are they possible?
Yes—many agencies offer cross-island drop-offs, but policies vary and additional fees may apply. If you plan a post-drive stay in Hilo or want to start in Kona, book early, compare rates, and confirm cross-island terms to avoid surprises.

Safety, weather, and driving tips for island roads
Islands roads have quirks, especially when weather shifts quickly or wind gusts pick up at higher elevations. A few practical reminders help you stay safe and enjoy every mile:
Road conditions and seasonal considerations
Central highland routes can bring fog, mist, and cooler temperatures, while southern and coastal roads stay warm and dry most of the year. After heavy rains, some secondary roads may close briefly. Always check local updates before you depart and stay flexible for detours.
Best times to drive for comfort and scenery
To maximize comfort and minimize crowds, start early on longer drives, especially when linking multiple stops. The central corridor is typically most comfortable in the morning when air is crisp and visibility is best. For coastal and rainforest segments, late afternoon light adds depth to photos and keeps temperatures pleasant.
Frequently asked questions about the Kona to Hilo road trip
How long does the Kona to Hilo drive typically take?
Without stops, a direct cross-island drive takes roughly 2–3 hours along the central route, depending on weather and traffic. If you weave in several must-see stops along saddle, Hamakua, or the Volcano corridor, plan for a full day or more to enjoy nature walks, viewpoints, and detours.
Is it safe to drive on the Big Island?
Yes, with typical island awareness. Weather can change abruptly; rural roads may be narrower, and some routes face coastal winds or mist in the highlands. Adhere to posted limits, stay focused, and pack a small kit with water, snacks, a flashlight, and a charger when venturing into less-populated areas.
Can you take a bus between Kona and Hilo?
Public transit exists, but intercity service is limited and infrequent. For a cross-island transfer on a tight schedule, driving is usually more practical.
Is flying between Kona and Hilo a viable option?
Inter-island flights (KOA to ITO) are possible but often slower overall due to check-in and security. For most travelers, driving provides quicker, more flexible access to the island’s varied landscapes and stops.
Can you rent a car in Kona and return it in Hilo?
Cross-island one-way rentals are common but may incur additional fees. If your plan includes a multi-day island loop, confirm policies in advance, compare rates, and weigh convenience against extra charges.
Where to stay: choosing Kona or Hilo as your base
Your base shapes daily pacing and access to different experiences. Here are practical considerations for each coast as your home base.
Where to stay in Kona
Kona offers beachfront resorts, casual rentals, and boutique stays near town and along the coast. Choose an area with easy Saddle Road access and a range of dining options. If you’re into morning coffee tastings or sunset snorkeling, a beachfront or near-town location minimizes drive time and keeps evening options flexible.
Where to stay in Hilo
Hilo presents a rainforest ambiance with a walkable downtown and proximity to waterfalls, gardens, and the volcano region. An inland or coastal lodging choice provides convenient access to the park, University of Hawaii, and a distinct strand of island culture, shopping, and dining.
