The Hana highway is a string of one-lane bridges, waterfall pull-offs, and jungle so close to the pavement you hear it. Nobody does this road to make time. You wait your turn at the bridges, then spend the night on the other side, where the coast finally opens and the van stays put.
Haleakala is the other half of a Maui week. The crater floor sits above the cloud line, a wide bowl of cinder and dry rock, and sunrise from the summit lots is why people leave the beach in the dark. At the rim there are no trees in the way, the wind is real, and the temperature drop from the coast is the part that catches you. From June through November, hurricane season can close coastal county parks and put the Hana highway at landslide risk, and the Haleakala summit is still cold at sunrise in the middle of summer.
Waianapanapa State Park, on that Hana coast, is the state park that sells a campervan camping permit. The van area is small, so the site is the first booking and the van is the second. If you need more sleeping space than a campervan, Hawaii RV rentals are a different vehicle, and they still have to fit a permitted site.
You cannot roll up to Haleakala's highest lots in the dark and hope. As of September 2026 the park charges $30 per private vehicle, and sunrise is a separate $1 reservation for those four lots between 3am and 7am, bookable up to 60 days ahead and as late as two days ahead.
Campervan rentals on Maui are the island-level version of this trip, including the Hana night and the sunrise reservation.
The Big Island from Kilauea to the Kona coast
Kilauea's caldera steams in the middle of Hawaii Volcanoes National Park. The Chain of Craters road runs out through lava fields, black and bare, with that steam behind you. The volcano side and the Kona coast are separate nights on the biggest island.
Campervan rentals on the Big Island are how you stay on the volcanoes side, next to the caldera and the lava fields. The west side is dry and coastal, and campervan rentals in Kailua-Kona are how you stay on the Kona and Kohala beach parks.
Hawaii Volcanoes National Park charges $30 per private, non-commercial vehicle as of September 2026, and that pass covers up to 14 people in the van.
Waimea Canyon and Kauai's Napali cliffs
Waimea Canyon is a red-rock gorge you look into from the rim. The walls drop a long way, and the forest at Kokee sits on top of that drop. On the north shore the Napali cliffs come up in green flutes off the Kalalau trailhead, and that trailhead sits behind a reservation gate.
You need a Napali Coast camping permit to hike overnight past Hanakapiai, bookable up to 90 days ahead as of September 2026. Haena State Park is a separate day-use entry and parking reservation, and the paved road ends there. Campervan rentals on Kauai are the canyon overlooks, the Napali permits, and the county beach-park circuit.
Oahu's North Shore and Honolulu
Winter swell turns the North Shore into surf season, and Malaekahana is where that coast already has a campground. The water breaks off the point. Between Laie and Kahuku the old plantation towns sit right on the water, low and close to the sand. Honolulu is the day out.
Campervan rentals on Oahu run from the North Shore campgrounds through the windward county parks and over to the Waianae coast. Those county permits are their own system, and the North Shore sites fill when the swell is up.
Hawaii camping permits for a campervan
There is no vehicle ferry between the islands. A van rented on Maui stays on Maui. Same rule on every island, so you plan one rental per island rather than a hop.
Hawaii state park camping permits come from the DLNR system at $20 a night for residents and $30 for non-residents as of September 2026, per site for up to 10 people. Napali Coast State Wilderness Park is the exception and charges per person. Buy the permit online and print it before you arrive. A late flight does not get you a permit at the gate.
The statewide window is 90 days, except Oahu state parks and Kiholo State Park Reserve on the Big Island, which open at 30 days.
Each county also runs its own campground permits. Kauai's county parks are the version with a public fee page. They take reservations, they charge separately from the state, and they close on a weekday for maintenance. A state permit does not cover a county beach park.
Sleep in the van only at a campground that permitted that night.
