The Big Island might not look that big on a map, but once you’re on the road, you’ll quickly realize it packs a lot into its size. With over 300 miles of driveable coastline and more than 4,000 square miles to cover, a full circle drive is an ambitious — but doable — one-day adventure if you plan it right.
Here’s how to make it work safely and without missing the highlights.
Start Early, Like Really Early
If you’re doing the full loop from Kona, leave no later than 7 AM. Ideally 6 AM. The Big Island rewards early starters with clear skies, empty parking lots, and the version of Hawaiʻi that feels most like itself before the tour groups arrive. You’ll need every hour of daylight — a full loop including stops runs 10 to 12 hours.
Suggested Route (North from Kona)
Most full-loop drivers go counterclockwise — north from Kona up the Kohala Coast, across to Hilo, south through Volcano, and back up the Ka’ū coast to Kona. This puts the most dramatic coastal scenery early, when you’re freshest.
Kona to Waimea (1 to 1.5 hours)
Take Highway 19 north along the Kohala Coast. Stop at Hapuna Beach or Mauna Kea Beach for a sunrise walk if you left early enough. The resort coast is beautiful in the morning light. Continue through Kawaihae and climb to Waimea — the temperature drops noticeably and the landscape shifts to rolling ranch land. Stop for coffee in Waimea before heading east.
Waimea to Honoka’a and Waipiʻo Valley Lookout (30 minutes)
The Waipiʻo Valley overlook is a non-negotiable stop on this route. The 600-foot cliffs and the black sand beach far below are unlike anything else on the island. The descent road into the valley is currently restricted to residents and is extremely steep — the overlook is your legal and perfectly spectacular stop. Budget 30 minutes here.
Hāmākua Coast to Hilo (1 to 1.5 hours)
Highway 19 along the Hāmākua Coast is one of the most scenic drives in Hawaiʻi. Pull over at the Akaka Falls turnoff (a short walk, worth it), drive through the historic sugar town of Honoka’a, and roll into Hilo for lunch. Hilo is underrated — eat at one of the local spots near Hilo Bay, walk the farmers market if it’s Saturday, and fuel up.
Hilo to Hawaiʻi Volcanoes National Park (45 minutes)
From Hilo, Highway 11 climbs to the park entrance at about 4,000 feet elevation. Allow at least 2 to 3 hours in the park: Crater Rim Drive, a stop at the Kīlauea overlook, and Chain of Craters Road if active lava conditions allow. This is the centerpiece of the southern loop. Check the NPS website for current road and lava access before you go.
Punalu’u Black Sand Beach (30 minutes)
Continue south on Highway 11 and stop at Punalu’u — one of the few black sand beaches on the island and a regular resting spot for Hawaiian green sea turtles (honu). Don’t touch or approach the turtles; federal law protects them. It’s a quick stop that almost everyone wishes they’d spent more time at.
Ka’ū Coast Return to Kona (1.5 to 2 hours)
The southern return on Highway 11 is long, largely featureless, and the most tiring segment of the loop. Fuel up at Nāʻālehu (the southernmost town in the U.S.) and push through. The road improves north of the turnoff to South Point. You’ll arrive in Kona exhausted in the best possible way — and with a full Big Island story to tell.
Pacing and Safety Notes
- Build at least 2 hours of buffer into your plan. The Big Island consistently surprises people with how long everything actually takes.
- Plan fuel stops in Waimea, Hilo, and Nāʻālehu. Stretches between these towns can exceed 50 miles with no services.
- Download offline maps before you leave. Cell signal drops in Volcano, the Ka’ū coast, and parts of the Kohala highlands.
- Don’t try to hit every detour. Green Sand Beach, Mauna Kea, and the south tip of Ka Lae each deserve their own day trip. Fit one per loop, not all three.
- The loop takes 10 to 12 hours with stops. Start before 7 AM and you’ll be back in Kona before 8 PM.
The Overnight Option: Two-Day Circle with a Hilo Stop
The full circle in one day is aggressive ? 220 miles with stops takes 12-14 hours. If your schedule allows, splitting it over two days with a Hilo hotel night is the local preference. Drive Kona to Hilo via Saddle Road on day one (stopping at Mauna Kea or Volcanoes), then the Hamakua Coast, Waipio Overlook, and back to Kona on day two. The pacing is relaxed, you see the north coast in proper morning light, and you aren’t exhausted for your flight home.
What to Pack for the Full-Circle Route
- Layers: temperature swings from 85?F at Kona beach to 40?F on Mauna Kea summit ? all in one day
- Reef-safe sunscreen: most Big Island beaches now enforce it
- Cash: Hilo farmers market vendors, roadside poke stands, and some parking areas are cash-only
- Full tank from Kona: gas stations thin out between Waimea and Waipio; fill up in Kamuela
- Download offline Google Maps for the Puna district ? cell coverage drops near Pahoa
Vehicle Recommendation for the Full Circle
The Wrangler Rubicon is the full-circle vehicle: it handles Saddle Road, can take the summit road if you add that detour, fits comfortably on Chain of Craters Road, and has enough seat height for the Waipio Overlook without climbing out on loose gravel. The Grand Wagoneer is a strong second for four or more passengers who want comfort over the long miles. Check availability for your travel dates.
