The route that gives Hawaii more than the Waikiki hotel strip that the package holiday sells: two days on the Big Island for the Kīlauea volcano (the most active volcano on Earth — the lava entry into the sea visible at the Kalapana coast when the eruption is active, the specific encounter with the planet in the act of making itself that no other destination gives at this accessibility) and the Mauna Kea summit at 4,205 metres (the specific astronomy destination — the 13 world-class observatories on the summit visible from the visitor centre, the summit stargazing giving the lowest light pollution of any accessible point in the Pacific), two days on Maui for the Hana Highway (the 65km road through 59 bridges and 617 curves with the bamboo forest and the black sand beach and the ‘Ohe’o Gulch pools visible from the road), and three days on the North Shore of O’ahu for the Banzai Pipeline (the December-February surf break — the most specifically dangerous and specifically beautiful wave in the world, the specific tube visible from the beach at Ehukai at 7am before the spectator crowd arrives).

Hawaii is the 50th US state and the most geologically active island chain in the Pacific — the Hawaiian Islands are the surface expression of the Hawaii hotspot, the mantle plume that has been producing the volcanic chain for 70 million years, moving northeast as the Pacific Plate moves northwest. The Big Island (the island of Hawaii — the youngest and largest, 10,433 square kilometres) is the island currently over the hotspot and is actively growing. The specific Hawaii quality: nowhere else in the accessible world gives the planet’s geology at this pace and this scale.
Before You Leave
Getting there: Fly London-Honolulu (via Los Angeles or San Francisco — 22-24 hours total, the specific long Pacific haul) or London-Kona on the Big Island (via the US West Coast). UK citizens: ESTA required (USD 21 / £16.54 at esta.cbp.dhs.gov).
The inter-island routing: Hawaiian Airlines and Southwest Airlines serve the inter-island routes (USD 60-150 / £47-118 per leg). The specific 7-day routing: fly into Kona (Big Island), Big Island circuit, fly Kona-Kahului (Maui), Maui circuit, fly Kahului-Honolulu, O’ahu North Shore, fly Honolulu-London.
The Route
Big Island: Kona base (2 nights) → Maui: Kahului/Hana base (2 nights) → O’ahu: North Shore base (3 nights)
DAYS 1-2 — The Big Island
Day 1: Kīlauea and Hawaiʻi Volcanoes National Park
Hawaiʻi Volcanoes National Park:
The Kīlauea caldera (the summit caldera of the world’s most continuously active volcano — the lava lake visible within the Halemaʻumaʻu crater when the eruption is in the summit phase, the sulfur dioxide visible as the plume rising from the crater):
The specific visitor instruction: the eruption status changes — visit the USGS Hawaiian Volcano Observatory at volcanoes.usgs.gov for the current activity level before the park visit. The park (entry USD 35 / £27.56 per vehicle, valid 7 days) is accessible regardless of the eruption level; the specific lava encounter depends on the current activity.
The Thurston Lava Tube (the 500-year-old lava tube — the tunnel formed when the lava flow’s outer crust cooled and solidified while the inner lava continued flowing and drained out, the specific underground geology accessible at walking pace):
Day 2: Mauna Kea Stargazing
The Mauna Kea Summit:
The Mauna Kea (4,205 metres — the highest point in Hawaii, the specific altitude that gives the lowest water vapour and the clearest atmospheric view of any accessible observation site in the world, the reason 13 world-class observatories are on the summit):
The Mauna Kea Visitor Information Station at 2,804 metres (the visitor centre open to the public, the free stargazing programmes on clear nights — the ranger-operated telescopes, the constellation tour, the galaxies visible from the VIS):
The summit (4,205 metres): accessible by the 4WD road (the last 14km requires the 4WD, the VIS has the rental equipment information). The summit at sunset (the shadow of the Mauna Kea visible on the cloud layer below as the specific mountain sunset visible from above the cloud) and the summit at night (the Milky Way from 4,205 metres without atmospheric interference).
The cultural context: Mauna Kea is sacred to the Native Hawaiian people — the mauna (mountain) is the physical connection between the Earth (honua) and the sky (lewa), the summit the domain of the deities. The Thirty Meter Telescope (TMT) construction controversy (the 2015-present dispute over the new telescope’s construction on the summit sacred land) is the specific Hawaii political event that the visitor who is on the summit should understand. The visitor centre has the cultural context information.
DAYS 3-4 — Maui
The Road to Hana:
The Hana Highway (the Maui Route 360 — the 65km road from Kahului to the Hana town, the 59 bridges and the 617 curves, the trailheads visible at the road’s edge for the waterfall hike and the bamboo forest walk):
The Pipiwai Trail (the 4km trail through the bamboo forest to the Waimoku Falls — the bamboo forest giving the specific sound (the hollow bamboo knocking in the wind, the canopy rustling) and the specific light (the green tunnel, the midday sun filtered to the forest floor)):
At 7am: the Hana Highway before the rental car convoy begins at 9am. The road shared with 10 other cars at 7am and with 200 at 10am.
The ‘Ohe’o Gulch (Seven Sacred Pools):
The ‘Ohe’o Gulch (the series of pools in the Haleakalā National Park — the swimming in the lower pools accessible when the water level is safe (the flash flood risk requires the current conditions check at nps.gov/hale)):
DAYS 5-7 — O’ahu North Shore
The Banzai Pipeline:
The Banzai Pipeline (the surf break at the Ehukai Beach Park on the O’ahu North Shore — the reef break that produces the specific hollow right-hand tube that the surf community regards as the most technically challenging and most visually dramatic single wave on Earth):
The Pipeline runs from November to February (the North Shore swell season — the northwest Pacific swells generating the 4-8 metre surf that the Pipeline break shapes into the specific tube). At 7am: the beach before the spectator crowd arrives at 9am.
The specific Pipeline instruction: the Pipeline is not safe to surf without the expert level competence and the local knowledge. The beach at Ehukai gives the full encounter from 10 metres — the tube visible from the shore, the surfer visible inside the tube, the specific Pipeline moment available to the spectator at full resolution.
The North Shore food trucks:
The North Shore food trucks at the Haleiwa Town (the garlic shrimp (macadamia nut garlic shrimp — the Giovanni’s Shrimp Truck, the specific North Shore food institution, the plate lunch at USD 14 / £11.02)) and the acai bowl (the Waialua Bakery, the Big Wave açaí bowl at USD 12 / £9.45 — the local açaí with the Big Island honey and the granola):
The Waimea Bay:
The Waimea Bay (the winter surf break adjacent to the Pipeline — the big wave surfing, the 6-metre faces visible from the bay shore in the December-February swell, the jump rock (the cliff above the bay from which the local population jumps into the bay, free, the specific Waimea Bay social institution)):

Hawaii is expensive — the most expensive domestic US destination and the most expensive Pacific Island destination. The specific Hawaii value is the specific Hawaii geology, culture, and landscape that no other destination provides.
