Which Island for a Road Trip?

Top beach: Road to Hana

Iconic 64-mile drive with 620 curves and 59 bridges

Big Island — The Ultimate Hawaiian Road Trip

The Big Island is twice the size of all other Hawaiian islands combined, making it the only island where a road trip feels like a genuine multi-day driving adventure. The 225-mile loop around the island passes through 11 climate zones, from tropical Hilo rainforest to volcanic desert to sunny Kohala Coast resort country. In a single day, you can drive through black lava fields, past waterfalls, around a volcanic caldera, and end at a white-sand beach. The Hamakua Coast scenic drive from Hilo north is one of the most beautiful stretches of highway in the state.

Road trip beaches: Hapuna Beach as your Kohala Coast base, Punaluʻu Black Sand Beach for a mid-loop stop, Richardson Beach for a Hilo beach break, and Makalawena Beach for a detour to a hidden cove.

Costs: Full-island loop requires a full day (5–7 hours of driving plus stops). Rental car is essential ($50–$100/day). Gas costs more than the mainland ($4.50–$5.50/gallon). National park entry is $30/vehicle.

Best timing: Year-round for the full loop. Start early (7am) to beat afternoon clouds on the Hilo side. The Kohala Coast is sunny all year. Allow 3–4 days minimum to do the road trip justice with beach stops and side excursions.

Maui — Road to Hana, One Iconic Drive

Maui’s Road to Hana is the most famous drive in Hawaii: 64 miles, 620 curves, 59 bridges, and 50+ waterfalls along a rainforest coastline. It is a full-day commitment (10–12 hours round trip with stops) that rewards with bamboo forests, black sand beaches, roadside fruit stands, and the pools at ʻOheʻo Gulch. Beyond Hana, the Backside Road continues through ranch country and past Kaupo Gap for an adventurous (rough road) return to civilization.

Road trip beaches: Hamoa Beach near Hana for a mid-drive beach break, Waiʻanapanapa State Park for black sand and sea caves, and Red Sand Beach in Hana for a dramatic cove (accessed by a slippery trail—use caution).

Costs: The drive itself is free (gas and snacks are the expense). Haleakalā National Park entry (ʻOheʻo Gulch) is $30/vehicle. Guided Hana tours (someone else drives) run $150–$250 per person. Pack food—options past Paʻia are limited.

Best timing: Start by 7am to avoid traffic. February–April offers the best waterfall flow. Avoid rainy days—the road becomes slippery and dangerous. Book Waiʻanapanapa parking reservations in advance.

Oʻahu — Compact but Varied

Oʻahu can be circled in about 3–4 hours without stops, making it the most compact road trip island. The drive from Waikiki to the North Shore through the center of the island, then along the windward coast back to town, covers Oʻahu’s full range: urban Honolulu, pineapple fields, surf towns, rugged windward cliffs, and suburban bedroom communities. The route from Kaneʻohe to Laʻie along the windward coast is particularly scenic.

Road trip beaches: Kailua Beach for a windward stop, Waimea Bay for the North Shore, Sunset Beach for the surf culture stretch, and Sharks Cove for a snorkeling break (summer only).

Costs: Rental car ($40–$80/day) or TheBus for a budget version. North Shore food trucks are the best road trip meal option ($14–$22). Gas costs are moderate given the short distances.

Best timing: Start early on a weekday to avoid H-1 traffic. Summer is best for swimming at North Shore beaches. The east coast from Laʻie to Kaneʻohe is the scenic highlight regardless of season.

Kauaʻi — Two Dead-End Roads, Maximum Scenery

Kauaʻi’s road system is unique: there is no road circling the island. Two roads diverge from Līhuʻe—one heading north to Haʻena (end of the road) and one heading west to Polihale (end of the road). This means every drive is a there-and-back journey, but both routes are spectacularly scenic. The north shore drive passes through Hanalei Valley lookout, Princeville, and ends at Keʻe Beach trailhead. The west route climbs to Waimea Canyon before descending to remote Polihale.

Road trip beaches: Anini Beach on the north shore drive, Tunnels Beach near the end of the north road, and Polihale State Park for the endpoint of the western drive. Poipu Beach is a south shore base between the two routes.

Costs: Haʻena State Park requires $5 parking + $5 entry reservations. Waimea Canyon lookout parking is $10. Polihale is free but needs 4WD. Total driving distances are short (under 40 miles per route).

Best timing: Both routes work year-round, but the north shore drive is more rewarding May–September when the beaches are swimmable. Waimea Canyon is best in the morning before afternoon clouds obscure the views.
