What to Pack for Hawaiʻi: A Local's Updated List (2026)

Every time someone asks me what to pack for Hawaiʻi, I want to shake my head at the massive, 50-item checklists floating around the internet. You know the ones—the ones that make you think you need seventeen sundresses, a formal gown, and enough shoes to fill a second suitcase. I get it. You’re excited. You’re picturing Instagram photos and sunset dinners. But here’s the truth from someone who’s lived here and watched countless visitors arrive with luggage they barely open: you don’t need nearly as much as you think.

This guide is a refresh of what I originally wrote back in 2017, and it reflects what locals actually bring when we travel between islands or for visiting family. It’s realistic. It’s practical. And most importantly, it won’t weigh you down while you’re exploring our islands. Whether you’re heading to Oʻahu, Maui, Hawaiʻi (the Big Island), Kauaʻi, or any of our smaller islands, this list works for everyone—with a few island-specific tweaks I’ll walk you through.

Let me break down what you actually need versus what the tourism boards want you to buy.

What Most People Overpack

The number one category of overpacking? Clothes. I watch people arrive with eight pairs of shorts and twelve shirts for a week-long trip. Most of your time here, you’ll be wearing the same rotation of beachy basics—and honestly, you’ll probably rewear the same clothes multiple times without thinking twice about it.

The thing about Hawaiʻi is that our laundry situation is different. Even if you’re staying in an Airbnb or condo without a washer, there are laundromats everywhere, and many visitors grab clean clothes for under ten bucks when needed. Your hotel or rental usually has laundry facilities too. This means you can pack three to four pairs of shorts instead of eight, and you’ll be absolutely fine. The same goes for lightweight shirts—bring four or five max, and you’ll rotate through them without issue.

Another major offender: footwear. People pack heels, dress shoes, sneakers, hiking boots, water shoes, flip-flops, and sandals, thinking they’ll need every option. Here’s what I’m telling you to actually bring: one pair of comfortable, easy-to-walk-in sandals and one pair of hiking shoes. That covers ninety percent of what you’ll do. The fancy dinner you’re imagining? A nice pair of flat sandals or strappy sandals works perfectly. I’ve never heard anyone say they regretted not bringing heels to Hawaiʻi.

Heavy jackets are another waste of luggage space. Unless you’re specifically heading up to Mauna Kea on the Big Island for stargazing or you’re caught in a rare cold snap in January, you won’t need anything heavier than a lightweight rain jacket. And even then, you can sometimes buy or borrow one here rather than cramming it in your checked bag.

The True Essentials

Now let’s talk about what you actually cannot skip. Some of these might surprise you—not in terms of their presence on packing lists, but in terms of their importance when you’re actually here.

First and foremost: reef-safe sunscreen. I’m not exaggerating when I say this is the law in Hawaiʻi now. Back in 2017 when I first wrote about packing, reef-safe sunscreen was more of a suggestion. Today, it’s mandatory. Hawaii’s state law, which took effect in 2021, bans oxybenzone and octinoxate in all sunscreens. But it gets stricter: Maui County went even further in 2022, banning all non-mineral sunscreens entirely. The County of Hawaii on the Big Island has the same rule. This means you can only use mineral sunscreens with zinc oxide or titanium dioxide as active ingredients. When you’re choosing, look at the label—if it doesn’t say “mineral” or “physical sunscreen” with zinc oxide or titanium dioxide, don’t bring it. Most major retailers have updated their shelves, but if you have old sunscreen at home, leave it behind. Buying reef-safe sunscreen here is easy and just as affordable as what you’d grab at home.

Next: a reusable water bottle. Seriously. This single item changes how you experience these islands. Fill it up at your hotel or any tap, and you’ll stay hydrated on hikes, at the beach, and while exploring. The sun here is intense, and dehydration sneaks up on people. A good insulated bottle keeps water cold throughout the day, which makes you actually want to drink more. Bring one from home if you have a lightweight stainless steel bottle, or grab one here for fifteen to twenty bucks. Either way, this is non-negotiable.

Good sandals matter more than most people realize. I’m not talking about luxury brands here—just something that won’t break or fall apart in a day of walking. Locals tend to grab Birkenstocks, Rainbows, or even basic rubber flip-flops and wear them into the ground. Your feet will thank you because our terrain varies wildly, from smooth sand to sharp lava rocks. Cheap flip-flops often snap when you’re halfway through a trail, and then you’re walking barefoot through volcanic terrain. Not ideal.

And while we’re on footwear: one pair of solid hiking shoes. These are non-negotiable if you’re planning any hikes beyond a casual beach walk. Our trails range from muddy and slippery (especially on the windward side and Kauaʻi) to legitimately rocky and sharp. Hiking shoes with good grip and ankle support keep you safe and comfortable. I recommend bringing these from home since finding your exact size and fit here might be frustrating.

Clothing: Light, Breathable, and Practical

When it comes to what to actually wear while you’re here, the mantra is simple: light, breathable, and quick-drying. Cotton is perfectly fine, but merino wool blends and moisture-wicking synthetic fabrics are your friends if you’re planning active days. The humidity means your clothes will feel damp sometimes, and you’ll appreciate things that dry fast.

Bring three to four pairs of shorts. Mix it up: maybe two pairs of beach shorts, one pair of hiking shorts, and one slightly nicer pair you can wear to a casual dinner. That’s plenty. Add in four or five lightweight t-shirts, tank tops, or casual tops depending on your preference. One lightweight sundress or loose shirt is great for covering up at the beach or wearing around town. These should be clothes you feel good in and don’t mind rewearing multiple times—because you will.

One outfit that’s dressier than beachwear is smart to pack. You don’t need formal wear—Hawaiʻi is casual, even at upscale restaurants. A nice sundress, linen pants with a simple blouse, or nice shorts with a pretty top works for dinner. Pair it with your nicer sandals, and you’re set. I’ve worn the same sundress to three different restaurants over different trips, and nobody noticed or cared.

A rashguard or lightweight swim shirt is a smart addition if you’re planning any water time. Not only does it protect you from the sun on your torso while snorkeling or swimming, but it gives you an extra layer in situations where you’re not sure of the dress code. Many locals who spend a lot of time in the water swear by them.

Finally, a rain jacket or lightweight windbreaker is essential. The funny thing about Hawaiʻi weather is that despite the tropical reputation, we absolutely get rain. The windward sides of the islands—especially Kauaʻi and parts of Oʻahu and Maui—get significant rainfall. A compact rain jacket packs down small and weighs almost nothing. When you need it, you’ll be grateful it’s in your bag. Pack one that’s easy to roll up and fits in a small corner of your luggage.

Beach Gear: What to Bring Versus What to Buy

Beach items are a tricky category because some things are worth their luggage space and others just aren’t. Here’s my breakdown.

Bring a microfiber travel towel. These are game-changers. They’re compact, lightweight, dry incredibly fast, and are large enough to actually use at the beach. You can find them everywhere for under ten bucks, and once you use one, you’ll never pack a regular beach towel again. Most hotels provide towels anyway, but for day trips to beaches and snorkeling spots, a personal travel towel is worth the space.

The snorkel gear debate is interesting. Some people swear by bringing their own set because fit matters and they already own quality gear. Others buy locally. If you’re a casual snorkeler, honestly, rent or buy a basic set here for twenty to thirty dollars. If you’re a serious snorkeler with specific mask and fin preferences, bring your set from home. What you shouldn’t do is check a checked bag filled with snorkel gear you might use once. That’s the move of someone who’s never actually packed for a trip to Hawaiʻi before.

Dry bags and wet bags are legitimately useful if you’re planning water activities. A dry bag keeps your phone, keys, and wallet safe during boat tours, kayaking, or waterfall visits. Wet bags contain your damp swimsuit so it doesn’t soak everything else in your luggage. If you already own these, bring them. If not, they’re cheap and easy to grab here or pick up before your trip.

Skip the beach cover-ups and wraps. I know they look cute in ads, but realistically, you’ll either wear your shirt or rashguard over your swimsuit, or just rock the swimsuit alone. The fancy cover-up stays in the suitcase. Same goes with linen pants for beach days—they take up space and you probably won’t reach for them over your shorts.

Tech and Electronics: Practical Additions

A waterproof phone case or pouch is essential if you’re planning any beach time, hiking near waterfalls, or water activities. Phone damage from water is the number one travel mishap I see, and a simple waterproof case costs ten to fifteen bucks and weighs nothing. Get one that actually floats if you can—then even if it accidentally ends up in the water, you can fish it out.

A GoPro or basic action camera is optional but increasingly popular for capturing underwater snorkeling footage and action shots on hikes. If you already own one, absolutely bring it. If not, don’t buy one specifically for this trip. Phones now take surprisingly good photos and videos, and you don’t need additional gear to have great memories.

A portable charger is smart insurance. Hawaiʻi’s sun and constant outdoor activities drain batteries faster than you’d expect, and finding an outlet while you’re out exploring isn’t always convenient. A lightweight portable charger keeps you connected and able to capture photos without hunting for a plug.

Bring your charging cables and an adapter if needed. International visitors, check what type of outlet Hawaiʻi uses—it’s the standard US two-prong and three-prong outlets. If you’re coming from outside North America, grab an adapter before you travel.

Health and Safety: Don’t Forget These

A basic first aid kit is smart. Include band-aids for blisters (because hiking on volcanic terrain can cause them), antibiotic ointment, and pain relievers. Most hotels provide basic stuff, but having your own is convenient and gives you peace of mind. If you take regular medications, bring enough for your entire trip—don’t assume you can easily find specific prescriptions here.

If you’re sensitive to motion sickness and planning boat tours, bring medication. Hawaiʻi’s waters are generally calm, but the ocean unpredictably gets choppy, and some boats are rockier than others. Having ginger pills, dramamine, or whatever works for you means you won’t miss out on activities because of seasickness.

Aloe vera gel is almost mandatory. Even if you’re diligent with sunscreen, you might get a little pink, and having aloe on hand is a game-changer. Most drugstores here have it, so you could wait and buy it locally, but having it in your luggage the moment you arrive is convenient. Get pure aloe or aloe with a bit of lidocaine for pain relief.

Insect repellent is smart, especially if you’re planning hiking or spending time in lush, green areas. Mosquitoes exist in Hawaiʻi and can carry dengue fever. A simple DEET-based repellent works fine. Many stores carry it, but having some from home means you’re protected your first day if needed.

One small thing most people don’t think about: a money belt or neck wallet. Honolulu, especially Waikiki, has pickpockets. Tourists with cameras, expensive phones, and wallets are targets. A simple neck wallet or money belt that sits under your clothes keeps your ID, passport, and credit cards safe while you’re walking around busy tourist areas.

What NOT to Pack: The Definitive No-List

I want to be explicitly clear about things that take up valuable luggage space and never get used. Leave your heavy jackets at home unless you specifically know you’re heading to high elevation. Leave formal wear—the fancy dress, the suit, the dress shoes. Leave most of your shoes at home. Leave hair styling tools (blow dryers, flat irons, curling irons) unless your hair genuinely requires them—the humidity here means your hair will do its own thing anyway, and tools just add weight and take up electrical outlets. Leave fancy accessories and jewelry. Leave thick jeans, long pants beyond one pair of linen or lightweight material, and anything that doesn’t breathe.

Don’t bring full-size bottles of toiletries. They’re heavy, take up space, and you can grab what you need here. Bring travel sizes or plan to buy locally. Hotels provide basic shampoo and conditioner, and drugstores carry everything else at reasonable prices.

Island-Specific Packing Tips

Each island has its own personality and weather patterns, and packing adjustments matter.

Kauaʻi is the wettest island, especially on the windward side and in central areas like the Wailua region. If you’re heading to Kauaʻi, definitely pack a rain jacket and consider bringing an extra pair of hiking pants or shorts that can handle mud and wet trails. Kauaʻi rewards you with lush green landscapes and waterfalls, but you’ll need to dress for the moisture.

The Big Island is massive with elevation variations. If you’re planning to visit Haleakala or Mauna Kea for stargazing, bring a warm layer—a fleece or lightweight sweater. At high elevations, it gets cold, especially at night. The rest of the island is warm and dry, but that summit temperature is shocking if you’re not prepared.

Maui and Oʻahu are generally similar to what I’ve described—warm and tropical. Maui’s west side is drier, while the road to Haleakala gets chilly as you climb. Oʻahu varies by area, but overall, the standard Hawaiʻi packing approach works perfectly.

If you’re planning serious hiking on any island, definitely review specific trails beforehand. Some require hiking boots with aggressive tread, while others are fine with regular hiking shoes. Checking trail reports means you can pack the right footwear instead of generic options.

Carry-On Versus Checked Luggage: Practical TSA and Airline Tips

As of 2026, TSA rules remain consistent with what they’ve been for years. Your carry-on needs to fit in the overhead bin, and the standard size limit for most airlines is 22 x 14 x 9 inches, with Southwest allowing slightly larger bags at 24 x 16 x 10 inches. Your personal item must fit under the seat in front of you. The 3-1-1 liquid rule is still in effect: 3.4-ounce bottles or smaller, all fitting in one quart-sized bag. Sunscreen counts as a liquid, so if you’re packing large bottles, they need to go in checked luggage.

For interisland travel (because Hawaiʻi’s best experience involves island hopping), Southwest offers two free checked bags per person, which is incredible. Hawaiian Airlines charges for checked bags but includes one carry-on and one personal item free. This changes your packing strategy. With Southwest, you can pack more casually and check a bag. With Hawaiian, you’re more limited, and packing efficiently matters more.

My advice: if you’re traveling with Southwest between islands, check a bag for more flexibility. If you’re with Hawaiian, pack lighter and use a carry-on when possible. For the main flight from the mainland to Hawaiʻi, most people use checked luggage anyway because they’re arriving with enough stuff for their whole trip.

One more TSA note for 2026: as of February 1, 2026, if you don’t have REAL ID-compliant identification, you’ll need to pay a $45 fee to use TSA’s Confirm.ID identity verification process. This has been rolling out gradually, but it’s fully in effect now. Check your driver’s license to make sure it has the REAL ID star before you travel.

Packing light for Hawaiʻi isn’t deprivation—it’s liberation. You’ll move faster through the islands, navigate airports more easily, and honestly, you’ll dress better because everything you bring actually fits your body and makes you feel good. The islands have everything you need if you forget something, and the local vibe is so casual that you’ll probably feel overdressed if you try too hard. Come as you are, pack smart, and focus on experiences instead of luggage. That’s the local way.
