You’ve got one trip, probably a week, and three islands people keep recommending. Everyone you ask gives a different answer and says it with total confidence.
So let’s cut through it. These islands are genuinely different, they suit different trips, and picking wrong is the difference between a great holiday and a slightly frustrated one.
Short version at the top: Oahu if it’s your first time or you want things to do. Maui if you want the classic resort holiday with a bit of adventure. Kauai if you want to be outside and don’t care about nightlife.
Oahu: The One With Everything
Oahu has Honolulu, which means it has a real city on it. About a million people, proper restaurants, museums, traffic jams and a nightlife that exists.
Waikiki is the famous beach and it is a wall of high-rise hotels, which puts some people right off. Fair. It’s also genuinely convenient, the swimming is easy, and you can learn to surf on gentle waves with Diamond Head sitting behind you.
Pearl Harbor is here, and it’s a serious, well-done memorial that takes half a day. Book the USS Arizona tickets ahead, they release online at set times and go instantly.
The mistake is thinking Oahu is only Waikiki. Drive forty minutes and you’re on the windward side with cliffs, or the North Shore with farmland.
Oahu’s Other Half
The North Shore in winter is where the big-wave surfing happens, waves of 20 to 30 feet at Pipeline and Waimea Bay, and watching it from the beach is genuinely frightening.
In summer the same beaches are flat and calm enough to swim. Two completely different places depending on the month.
The shrimp trucks at Kahuku are a proper institution, garlic shrimp served on paper plates from converted vans, and they’re the best cheap meal on the island.
Hanauma Bay is a flooded crater with a reef right off the beach. Reservations required, closed Mondays and Tuesdays, and you watch a conservation video before you’re let in. Worth every bit of the faff.
▶ Watch This Before You Go
Maui: The Classic Choice
Maui is the one most people picture. Resorts along the west and south coasts, reliable sun, calm swimmable beaches, and a very well-oiled holiday machine.
The Road to Hana is the headline drive: 64 miles, 620 curves, 59 bridges, waterfalls and rainforest. It takes a full day and it’s beautiful. It’s also a lot of car sickness and you should treat it as a whole day, not a morning.
Snorkelling here is the best of the three for casual swimmers. Molokini crater is a half-sunk volcanic ring you boat out to, and the visibility is genuinely absurd.
One thing to be aware of: Lahaina was devastated by fire in 2023 with significant loss of life. Much of the town is closed and rebuilding. Respect that, go where you’re welcome, and spend money on the island because tourism is the economy.
Maui’s Volcano
Haleakala is 10,023 feet and you can drive to the top, which takes about two hours from the coast and climbs through several climate zones.
Sunrise up there is the famous thing and requires a reservation booked well in advance, a 3am alarm and warm clothes, because it’s frequently near freezing while your hotel is at 24 degrees.
Honestly? Sunset needs no reservation, is nearly as good and you’ll have slept. The crater itself looks like Mars and you can walk down into it.
Kauai: The Wild One
The oldest of the main islands, and it shows. More eroded, greener, dramatically more mountainous, and about 70,000 people on the whole thing.
Waimea Canyon is fourteen miles long and 3,600 feet deep, red and green and completely unexpected on a tropical island. You drive up, stop at viewpoints, and it takes half a day.
The Napali Coast on the north west is the reason people come. Cliffs up to 4,000 feet dropping into the sea, no road access at all. You see it by boat, by helicopter, or by hiking the Kalalau Trail, which is spectacular and genuinely serious.
Hanalei Bay in the north is the prettiest bay on any of the islands, in my opinion. Mountains, waterfalls behind, a pier, and a small town that hasn’t been resorted to death.
The Kauai Catch
It rains. Mount Waialeale in the middle of Kauai is one of the wettest places on earth, over 400 inches a year, and the north shore gets a serious share of it.
The south and west coasts around Poipu are much drier, which is where the resorts cluster. If you’re going in winter and want sun, stay south.
Also: there is very little to do at night. A couple of decent restaurants and then bed. For some people that’s the whole appeal, and for others it’s a slowly dawning problem.
The Honest Comparison
Cheapest: Oahu, by a distance. More hotels, more competition, and a bus network that actually works so you can skip the hire car.
Best beaches for swimming: Maui, for consistency and calm water.
Best scenery: Kauai, not particularly close.
Best for a first visit: Oahu, because it has the widest range and the easiest logistics.
Best for a honeymoon: Maui, or Kauai’s north shore if you’d rather hike than lounge.
Best for families: Oahu for variety, Maui for the resort pools and easy sea.
Should You Do Two Islands?
In a week, no. Inter-island flights are quick, about 40 minutes, but you lose most of two days to airports, hire cars and check-ins.
Ten days or more, sure. Oahu plus Kauai is the best pairing because they’re so different. Maui plus the Big Island works too if volcanoes interest you.
One island for a week beats two islands for four days each. This is the single most common regret people report :/
Common Questions
Which Hawaiian island is best for first-timers? Oahu. Easiest logistics, widest range of things to do, and the cheapest of the three.
Do I need a rental car? On Maui and Kauai, absolutely yes. On Oahu you can manage without if you’re staying in Waikiki, though a car for a day or two opens up the island.
When is the best time to visit Hawaii? April to June and September to early December. Good weather, lower prices and fewer people than the winter and summer peaks.
Which island is most expensive? Maui, generally, followed by Kauai. Oahu has the widest range of prices because it has the most beds.
What about the Big Island? Worth its own trip. Active volcanoes, black sand beaches, snow on Mauna Kea, and it’s bigger than the other islands combined. Different holiday entirely.
