This is the page to read in the week before your trip. It covers everything that doesn’t fit neatly into the other guides — what to pack, what to book in advance, what to expect at the airport, how to be a respectful visitor, and the practical details that make the difference between a smooth trip and a stressful one.
Book These Before You Leave Oahu
Some things genuinely cannot wait until you land. These are the items that either sell out completely or become significantly more expensive if you wait:
Rental car — Book as early as possible. Maui has a serious car rental shortage and prices rise sharply as your dates approach. This is the one booking that can make or break your whole trip. If you don’t have a car on Maui, you’re limited to your resort area.
Haleakala Sunrise Permit — Required for independent visitors entering the summit between 3:00–7:00 AM. Book at recreation.gov. These sell out weeks or months in advance — sometimes within minutes of becoming available. If you can’t get a permit, book a guided sunrise tour instead, which doesn’t require one.
Waianapanapa State Park — The famous black sand beach on the Road to Hana requires advance reservations at gostateparks.hawaii.gov. Without one you’ll be turned away. Entry is $5/person plus $10/vehicle.
Iao Valley State Monument — Also requires reservations for out-of-state visitors. Book at gostateparks.hawaii.gov.
Molokini Snorkel Tour — Morning departures fill up fast in peak season. Don’t plan to book the day before.
Luau — Popular luaus fill up well in advance, especially during holiday periods and whale season (December–April).

What to Expect at Honolulu Airport (HNL)
Flying inter-island from Oahu is different from regular domestic travel in a few important ways that trip up first-timers every year.
You depart from the Inter-island Terminal, which is separate from the main international terminals at HNL. If you’re connecting from a mainland flight, you’ll need to collect your bags, clear any necessary checkpoints, and take a shuttle or walk to the inter-island terminal. This takes longer than most people expect — allow at least 90 minutes between a mainland arrival and your Maui departure if connecting on the same day.
Arrive at least 60–90 minutes before your inter-island departure. The inter-island terminal can get busy, especially during peak travel periods. This isn’t a commuter hop where you can slide in 20 minutes before departure.
Luggage considerations: Inter-island flights allow the same bags as any domestic flight, but checked bag fees apply on most airlines. If you’re only going to Maui for a few days, seriously consider traveling carry-on only — it saves money and speeds up your arrival at OGG.
Southwest’s free bags: If you have multiple checked bags, Southwest’s two free checked bags policy is a significant advantage on this route. Worth factoring into your airline comparison.
What to Expect When You Land in Maui
Kahului Airport (OGG) is a smaller, more relaxed airport than HNL. Baggage claim is fast and car rental pickups are straightforward — most companies are either on-site or a short shuttle ride away.
A few things to do the moment you land:
Fill up your gas tank in Kahului. Gas is significantly cheaper in Kahului than in the resort areas of Kaanapali or Wailea, and substantially cheaper than in Hana. Fill up before heading to your hotel.
Stop at Costco or Safeway in Kahului. Both are located right off the main road near the airport. Stocking up on groceries here — breakfast items, snacks, drinks, beach supplies — can save $300–$500 over the course of a week compared to buying everything in resort areas.
Download offline maps. Cell service is unreliable or nonexistent in parts of Maui, especially on the Road to Hana. Download your maps offline before leaving Kahului.
Pick up the Gypsy Guide app if you’re planning to self-drive the Road to Hana. It’s a GPS-triggered audio tour app that works offline and is far superior to trying to follow a list of mile markers.
Maui Packing List: What to Bring
Maui is casual — you won’t need anything formal — but there are a few specific items that many visitors wish they’d packed.
Absolute Essentials
Reef-safe mineral sunscreen — This is non-negotiable and worth understanding before you go. Hawaii banned sunscreens containing oxybenzone and octinoxate in 2021. Maui County went further in 2022 and banned the use of all non-mineral sunscreens — not just the sale. Guided tour operators will ask you to throw away non-compliant sunscreen before boarding. Your sunscreen must use zinc oxide or titanium dioxide as active ingredients. Check labels carefully — many products marketed as “reef-friendly” still contain harmful chemicals.
Warm layers for Haleakala — This surprises almost every first-time visitor. Haleakala summit sits at 10,023 feet and temperatures are regularly in the 30s–40s°F, even in summer. If you’re doing the sunrise tour (which starts at 3:00 AM), you’ll want a jacket, hat, and gloves. Don’t leave this to chance — it’s genuinely cold up there.
Light rain jacket — Maui has multiple microclimates and can go from sunny to rainy quickly, especially on the Road to Hana and in Upcountry. A packable rain jacket takes up almost no space and earns its place every trip.
Reef shoes or water shoes — Many of Maui’s best snorkeling spots have rocky entries. Water shoes make a big difference at places like Honolua Bay and some Road to Hana stops.
Rash guard — The Hawaiian sun is significantly more intense than most visitors expect, even those from sunny climates. A rash guard for snorkeling and beach days protects your back and shoulders far better than sunscreen alone.
Dry bag or waterproof pouch — Useful on snorkel tours and beach days to protect your phone and valuables.
Clothing
Maui is casual. The daily wardrobe for most visitors is swimwear, shorts, t-shirts or light linen, and sandals. For evenings at nicer restaurants, a sundress or collared shirt is typically sufficient — even Mama’s Fish House, one of Maui’s finest restaurants, doesn’t require formal attire.
- Swimsuits (2–3 — you’ll be changing often)
- Shorts and lightweight tops for daytime
- One or two nicer outfits for evening dining
- Light cardigan or wrap for cool evenings (it gets breezy)
- Comfortable walking sandals (Chacos or Tevas are popular for their water-friendliness)
- Hiking shoes or trail runners if you plan to hike Haleakala crater or Pipiwai Trail
- Warm jacket, hat, and gloves for Haleakala summit
Beach and Water
- Reef-safe mineral sunscreen (bring enough — it’s expensive on the island)
- Rash guard
- Snorkel mask and fins (rental gear is available everywhere, but your own gear fits better)
- Reef shoes or water shoes
- Wide-brimmed hat
- Polarized sunglasses
- Quick-dry towel (some hotels ask you not to take pool towels to the beach)
- Reusable water bottle (tap water on Maui is safe and high quality)
Practical Items
- Dry bag or waterproof phone case
- Bug spray (useful on the Road to Hana and in Hana’s jungle)
- Day pack for hikes and tours
- Portable charger / power bank
- Your Costco membership card (seriously — it’s worth using)
- Cash (some local spots are cash-only)
Leave These Behind
- Formal wear — you won’t need it
- Heavy shoes — leave the boots unless you’re doing serious hiking
- Too many clothes — Maui is hot and you’ll wear the same things on rotation
- Non-reef-safe sunscreen — you’ll have to throw it away anyway
What Maui is Like vs. Oahu
If you’re spending time on both islands, understanding the difference in pace and character helps you set the right expectations.
Oahu is urban, walkable (in Waikiki), and faster-paced. It has world-class dining, a lively nightlife, and the density of a city beach destination. You can get around without a car in the tourist areas, public transit exists, and there’s always something happening.
Maui is slower, more spread out, and more nature-focused. The pace is genuinely different — restaurants close early, nightlife is minimal outside of resort areas, and most of what makes Maui worth visiting requires getting in a car and driving somewhere. This isn’t a flaw — it’s the point. Maui rewards the traveler who is willing to wake up early, drive somewhere beautiful, and simply be there.
Practical differences to know:
- Most restaurants close by 9:00–9:30 PM — don’t arrive hungry at 8:45 PM expecting a full menu
- Cell service is unreliable in Hana and parts of the Road to Hana
- The island is significantly more car-dependent than Oahu — you’ll drive more than you expect
- Maui time is real — things move at a slower pace and that’s part of the experience
Cultural Respect: How to Be a Good Visitor
Maui’s residents have navigated significant challenges in recent years — the 2023 Lahaina wildfires were devastating, and the community is actively rebuilding. Tourism is essential to Maui’s economy (supporting roughly 75% of jobs on the island), and visitors are genuinely welcomed — but being a thoughtful guest matters.
Aloha is a value, not a greeting. The word means love, peace, compassion, and mutual regard. It’s the spirit that defines Hawaiian culture. Bringing that same spirit — patience, kindness, gratitude — to your interactions on the island is the most meaningful form of cultural respect.
Learn a few words: “Mahalo” (thank you) and “aloha” (hello/goodbye/love) go a long way. Locals genuinely appreciate the effort.
Respect Lahaina. The historic core of Lahaina is still being rebuilt after the 2023 wildfire. Visiting out of curiosity rather than genuine support for recovery has been a source of tension. The best way to support Lahaina is to eat at reopened local restaurants, buy from local vendors, and bring your aloha spirit — not disaster tourism energy.
Give wildlife space. Hawaiian green sea turtles (honu) are federally protected. You must stay at least 10 feet away from turtles on the beach and in the water. Monk seals — rarer and also protected — require 50 feet of distance. Never touch, chase, or block wildlife.
Use reef-safe sunscreen. Already mentioned, but worth repeating — it’s the law in Maui County and it matters for the reef ecosystem that makes snorkeling here so extraordinary.
Don’t take rocks or sand. It’s illegal to remove natural materials from Hawaii’s beaches and parks, and it’s deeply contrary to Hawaiian cultural values. Leave everything as you found it.
Follow trail and park rules. Several of Maui’s most popular natural sites require advance reservations (Waianapanapa, Iao Valley, Haleakala sunrise). These systems exist to protect both the natural environment and the experience for visitors. Respect them.
Support local businesses. Choosing locally owned restaurants, tour operators, and shops keeps more money in the Maui community. This is especially meaningful during the ongoing recovery from the 2023 fires.
Weather: What to Expect
Maui enjoys warm weather year-round, but there are meaningful differences by season and location.
Temperatures: Coastal areas stay between 75–88°F year-round. Higher elevations (Haleakala, Upcountry) are significantly cooler — sometimes 20–30 degrees colder than the coast.
Dry season (April–October): Sunny, dry, and warm. The best conditions for beach activities and snorkeling. Less chance of rain on the Road to Hana (though some rain is always possible in the rainforest areas).
Wet season (November–March): More rain, especially on the north and east sides of the island. Kihei and Wailea (South Maui) tend to stay drier than Kaanapali and Kapalua (West Maui). The Road to Hana gets significantly more rain in winter. The upside: whale season runs December through April and Maui’s humpback whale viewing is world-class.
Microclimates: Maui has dramatic weather variation across short distances. It can be raining in Hana while perfectly sunny in Kihei — both an hour’s drive apart. Don’t cancel Road to Hana plans based on morning weather in your resort area.
Ocean Safety: What Every Visitor Needs to Know
Hawaii’s ocean is beautiful and powerful. Respecting it is essential.
Check conditions before entering. Beach conditions change daily based on swell, wind, and currents. Check local surf reports and posted warning signs at each beach. A beach that was calm yesterday can have dangerous shore break today.
Shore break hazard. Beaches like Big Beach (Oneloa) in Makena have powerful shore break that causes injuries every year. Watch the waves for several minutes before entering, and don’t turn your back on the ocean.
Never swim alone. Especially at remote or unfamiliar beaches.
Coral cuts. If you’re snorkeling over shallow reef, cuts from coral are a real possibility. They heal slowly in the tropics — clean any cuts thoroughly and apply antiseptic promptly.
Sun intensity. The Hawaiian sun is genuinely more intense than most visitors are used to. First-day sunburns are extremely common among visitors who underestimate it. Apply reef-safe sunscreen 30 minutes before sun exposure and reapply every 90 minutes, especially after being in the water.
Dehydration. The combination of heat, saltwater, and activity depletes you faster than you expect. Drink water consistently throughout the day.
Driving in Maui: What’s Different
The Road to Hana is genuinely demanding. Over 600 curves, nearly 60 one-lane bridges, blind corners, and slow-moving tourist traffic in both directions. It requires your full attention. Don’t attempt it if you’re already tired, don’t put it off until afternoon, and don’t try to rush it.
Pull-over etiquette. If you’re driving slowly to look at scenery and there are cars behind you, pull over at the next available spot to let them pass. This is good manners on Maui’s narrow roads.
Never leave valuables in your car. Car break-ins happen at trailheads, beach parking lots, and scenic viewpoints across Maui. Take your valuables with you or leave them at the hotel.
Gas up strategically. Fill up in Kahului before heading toward Hana or Haleakala. Gas in Hana is very expensive and sometimes unavailable. Gas near resort areas is pricier than in Kahului.
Parking at popular sites fills early. Haleakala summit, Waianapanapa, and popular beach parks can have full parking lots by mid-morning. Arrive early — this is the single best piece of advice for avoiding frustration.

Frequently Asked Questions
Do I need ID to fly from Oahu to Maui?
Yes. Inter-island flights are domestic and require a valid government-issued photo ID — a driver’s license or passport both work.
Is Maui safe to visit in 2026?
Yes. Maui is open and actively welcoming visitors in 2026. The 2023 Lahaina wildfires affected a specific area of West Maui — all major resorts, beaches, the Road to Hana, Haleakala, and South Maui were unaffected and operating normally. Lahaina’s historic core is still being rebuilt, but much of Lahaina Harbor and surrounding areas have reopened.
What should I not do in Maui?
Don’t touch or approach sea turtles and monk seals. Don’t use non-reef-safe sunscreen. Don’t take rocks, sand, or coral from beaches or parks. Don’t leave valuables in your car. Don’t show up to popular sites late expecting easy parking. Don’t try to rush the Road to Hana.
Is it worth spending time on both Oahu and Maui?
Absolutely — they offer genuinely different experiences. A classic combination is 3–4 days in Oahu followed by 4–5 days in Maui. Oahu gives you Pearl Harbor, Waikiki, and a lively urban vibe; Maui gives you nature, quiet beaches, and iconic adventures like Road to Hana and Haleakala.
Can I use my phone on the Road to Hana?
Cell service is patchy to nonexistent on parts of the Road to Hana, especially past Ke’anae. Download your maps offline before leaving Kahului. The Gypsy Guide app works offline using GPS.
What is the inter-island terminal at HNL?
The inter-island terminal at Honolulu Airport is a separate facility from the main international terminals. All inter-island flights (including those to Maui) depart from here. If connecting from a mainland flight, allow at least 90 minutes between flights to make the transfer.
