Hawaii Travel Guide

The only decision that really matters in Hawaii is which island you book, and the honest answer for a one-week trip is: one of them. Oahu suits first-timers and anyone who wants city, history and surf in the same week. Maui is the beach-and-drives island. Kauai is for scenery and hiking. The island of Hawaii is for volcanoes and long drives. Pick by what you want out of the week, not by which name sounds most like a postcard.

Island-hopping is where good trips go to die. A flight between islands takes 30 to 50 minutes, which sounds trivial until you add checkout, the rental car return, the airport, the new rental counter and the drive to a new hotel. Each hop costs most of a day and one night’s sleep, and the islands aren’t so different that you need two of them in seven days. Two weeks, two islands. One week, one island. That single rule will improve your vacation more than any other advice on this page.

Which island, honestly

Oahu holds three quarters of the state’s population and every kind of Hawaii in one place: Waikiki, Pearl Harbor, the Chinatown food scene, and the North Shore’s winter surf an hour away. It is the cheapest island to reach and the only one with real public transportation, so it works if you’d rather not drive constantly. Honolulu gets its own guide: things to do in Honolulu.

Maui is the classic honeymoon-and-family island: long west and south shore beaches, the Hana Highway, Haleakala’s crater at 10,000 feet, and the best winter whale watching in the state. It is also the island where the 2023 wildfire hit, so read the section below before you plan around Lahaina.

Kauai is the oldest and greenest of the four, and the one with the most dramatic coastline. No road circles the island - the Na Pali cliffs break the loop - which means you see that coast from a boat, a helicopter or the Kalalau Trail, and nothing else. Waimea Canyon runs 10 miles inland and is worth a full morning.

The island of Hawaii, which everyone calls the Big Island, is larger than the other islands combined and has the climate range to prove it: black sand, rainforest, high desert and snow on Mauna Kea. It also has two airports on opposite coasts, Kona in the dry west and Hilo in the wet east, and a two-hour drive between them. If you book the wrong one you’ll spend your week commuting.

Lahaina, and what visiting with care means right now

The August 2023 fire destroyed most of historic Lahaina and killed more than a hundred people. Three years on, the town is a construction site and a community in the middle of rebuilding, not an attraction. The County of Maui says Front Street reopens to vehicular traffic on 1 August 2026 between Papalaua and Shaw streets, with the Ulu o Lele Marketplace, Kimo’s and more than a dozen other businesses coming back; Market Street, Papelekane Street and Mokuhinia Place stay closed while state harbor dredging continues.

Maui’s own leadership has been clear that visitors are welcome and that tourism pays a lot of local wages. What they ask is simple: spend money in West Maui businesses, stay out of residential burn areas, and don’t photograph people’s destroyed homes. Check mauirecovers.org, the county’s recovery site, in the week before you fly, because what is open changes month to month.

The reservations you cannot fix on arrival

Hawaii has moved its most-visited natural sites onto booking systems, and the windows are short and unforgiving. On Maui, entering the Haleakala summit district between 3 and 7 a.m. for sunrise requires a reservation made on recreation.gov; slots go live at 7 a.m. Hawaii time, a portion of each day’s allocation is held back and released 48 hours ahead, and one visitor can only hold one sunrise reservation in any three-day period. Summer weekend dates disappear fast. On Oahu, Diamond Head and Hanauma Bay both require non-resident reservations through their official systems - details are in the Honolulu guide.

Don’t trust a screenshot from someone’s 2023 blog post for any of this. Rules, windows and prices on the Hawaii systems have all changed at least once in the last two years. Book from the official site, the week the window opens.

You are going to be driving

Outside Waikiki, a rental car isn’t a convenience in Hawaii, it’s the trip. Book it at the same time as the flight: supply on the smaller islands is thin, and walk-up rates in July or at Christmas are eye-watering. Skip the convertible, take something you don’t mind parking at a trailhead, and download offline maps before you leave the hotel wifi, because coverage on the windward coasts and inside the craters is patchy.

Both of the famous drives punish rushing. Maui’s Hana Highway runs 52 miles from Kahului with roughly 620 curves and 59 bridges, most of them one lane, and the state’s own tourism office puts the one-way time at two to four hours. Doing it as a day trip means seven hours in the car for a handful of waterfall stops; staying a night in Hana turns it into the best day on Maui. On the island of Hawaii, the Kona-to-Hilo crossing is about two hours through five climate zones, which is either a highlight or a chore depending on whether you planned for it.

The volcano runs on its own schedule

Kilauea’s current summit eruption inside Halemaumau is episodic rather than continuous, and that is the part most volcano itineraries get wrong. Episode 51 started around 8:30 a.m. on 15 July 2026 and was finished by 4:46 that afternoon, with lava fountains reaching roughly 950 feet; USGS then forecast the next episode for somewhere between 25 and 29 July. In other words, the difference between seeing fountains and seeing a steaming crater can be 36 hours.

If lava is the reason you’re going, watch the USGS Hawaiian Volcano Observatory updates rather than a tour operator’s marketing, and keep your Big Island nights flexible. Also worth knowing before you commit: the summit area of Hawaii Volcanoes National Park is in the middle of a two-year construction project with rolling closures, and volcanic gas (locals call the haze vog) is a real problem for anyone with asthma.

When to go

Hawaii doesn’t have a bad season, only different ones. Humpback whales are in the islands from November through April, and Maui’s Auau Channel is the best place on earth to watch them from a boat or, on a good day, from the shore; federal rules keep boats and swimmers 100 yards away, so any operator promising a close encounter is selling something they shouldn’t.

Winter also brings the big north-shore surf, more rain, and peak prices between mid-December and early January. Summer flips it: calmer north shores, hotter and drier leeward coasts, and family crowds. The value windows are late April to early June and September to early November, when the water is warm, the rates soften and the trails are quieter. One budget note: Hawaii’s accommodations tax went up 0.75% from 2026 under the state’s climate “green fee” law, so the tax line on your hotel bill is a little heavier than older guides suggest.

The rules locals care about

Hawaii asks more of visitors than most US destinations, and the requests are reasonable. Sunscreens containing oxybenzone and octinoxate have been illegal to sell here since 2021 because of reef damage, so buy mineral sunscreen or bring a rash guard. Green sea turtles and monk seals hauled out on the sand are federally protected: give them room and don’t crowd them for a photo. Don’t stack rocks, take lava rock or sand, or walk into fenced sites - many are burial grounds or temples, not scenery.

And treat the ocean with more respect than the postcards suggest. Shore breaks snap collarbones, currents at unpatrolled beaches carry off strong swimmers, and the advice every Oahu lifeguard repeats is the simplest one going: swim where they are. Do that, keep the itinerary to one island, and Hawaii turns out to be a far easier place to travel than the planning makes it look.
