So last trip to Kauai, I bought this giant straw hat. Not just big. GIANT.
The kind that makes you look like you should be sipping champagne at the Kentucky Derby.
I saw it in a shop in Poipu and thought it would be perfect for photos. Which it was. For exactly one photo shoot.
Then it lived in our hotel room taking up half the closet because it wouldn’t fit back in my suitcase without crushing everything else.
My husband still brings it up.
I’ve been going to Kauai since I was 10 – over 40 trips now.
My grandma had a place there, my mom lives there full-time. I’m a Certified Hawaii Destination Specialist and a professional tourist (yes, that’s what I call myself).
You’d think I’d have packing figured out by now.
But every trip I either forget something important or bring something ridiculous.
The hat wasn’t even my worst packing decision. One time I packed three pairs of sandals but no athletic shoes. Had to buy some at the Costco in Lihue.
Here’s what I wish someone had told me before my first trip. Not the perfect Pinterest packing list, but the real one. The stuff that actually matters and the stuff you can skip.
Quick reality check: Kauai had over 1.3 million visitors in 2025. Tourist spending hit $2.85 billion, which is 49% higher than before the pandemic.
Translation? Everything in Hawaii is expensive. Forgetting stuff and having to buy it there adds up fast.
The average family drops about $2,040 per person on a Kauai trip. So yeah, packing smart actually matters.
What to Wear on the Plane (Because You Still Have to Get There)
This sounds dumb but everyone forgets they have to fly TO Hawaii before they get to wear their cute beach clothes.
I live in Seattle. Most of the year when we fly out, it’s cold and rainy here. So we wear our warmest stuff on the plane. Fleece jackets, sweatshirts, long pants.
I know it feels weird packing for Hawaii and then boarding the plane in a hoodie. But trust me. Airports are freezing. The plane is freezing.
And those same warm clothes work later if you drive up to Waimea Canyon where it gets legit cold.
Also – wear your bulkiest shoes on the plane. For us that’s hiking shoes. Saves so much suitcase space.
And please, I’m begging you, don’t fly in flip-flops. I’ve seen luggage fall on people’s feet in the overhead compartment area. Not worth it.
Carry-On Stuff That Actually Matters
The flight from the West Coast is about 6 hours. East Coast? Around 10. Most airlines stopped giving out real meals years ago.
Bring your own snacks. We pack protein stuff (nuts, jerky, that kind of thing), granola bars, crackers.
And approximately 47 more snacks for the kids than we think we’ll need. We always run out anyway.
Water bottles for everyone. This is non-negotiable with kids. Those little airplane cups? Disaster. We use Hydro Flasks in different colors so nobody fights over whose is whose.
We get the free drinks from the flight attendants but pour them into the water bottles. No spills, everyone’s happy.
Headphones. The absolute best birthday present my husband has ever given me (and we’ve been married 15 years) was Bose noise-canceling headphones.
They block out engine noise and crying babies without completely blocking out my own kids when they need me. I can watch a movie and arrive in Hawaii like a human instead of a rage monster.
Are they expensive? Yes. Worth it? Also yes. These are the ones.
Your electronics. I’m a blogger so my laptop comes with me in a laptop sleeve. The kids bring iPads and Nintendo Switches. Those iPad cases with the built-in stand are worth every penny for movies.
I used to bring my big camera but honestly now I just use my phone and this little DJI Osmo Pocket for video. Takes up almost no space and the footage is surprisingly good.
Charging cables and battery packs. Bring cables for everything. Those airplane USB ports are useless for actually charging iPads. They’re so weak. We wasted half a flight once waiting for an iPad to charge that never got past 5%.
Now we bring portable battery packs and charge stuff before we even board.
Don’t check your electronics. Ever. Carry-on only.
Clothes for Kauai (Less Than You Think)
Kauai is the most casual place you’ll ever go. Shorts, t-shirts, tank tops, sundresses. That’s it.
Swimsuits, obviously. We’re that family that gets matching ones because I’m extra. You need a coverup for walking around the pool or running to grab lunch.
Sun hats and sunglasses. Don’t skip these.
About winter in Kauai (December through March) – it gets into the 60s at night. If you’re from Minnesota you’ll think I’m crazy for saying that’s cold. But after a day in 80-degree weather wearing shorts, 60 at night feels FREEZING.
I get cold easily so I always pack a couple lightweight sweaters, one pair of long pants, and a maxi dress or two for layering. Winter is also rainy season. Throw in a rain jacket that folds up small. You’ll use it.
Packing for Babies and Toddlers
Taking a baby or toddler to Kauai? Pack enough clothes for the whole trip. Then pack extra for blowouts, spills, and whatever else toddlers do.
Bring all your own baby stuff. Diapers, wipes, bottles, formula, pacifiers, any medications. Hawaii is expensive and finding your specific brand of formula at 8pm when you’re jet-lagged is not fun. Ask me how I know.
SPF swimsuits and rashguards save you so much sunscreen reapplication. Worth it.
You need swim diapers for pools. Most resorts require them.
Walking toddlers need sandals and water shoes. I have a whole post on beach essentials for babies if you want more details.
For Bigger Kids
Enough clothes and swimsuits for the trip. Let your kids pick their own sun hats. If they don’t pick it, they won’t wear it.
I learned this with my oldest when he refused to wear the adorable hat I bought him and got a sunburned scalp instead.
One nicer outfit per kid for fancy dinners or luaus or if you’re doing a family photo shoot.
Here’s the thing nobody tells you until it’s too late: Kauai’s red dirt stains everything. EVERYTHING. If you’re hiking or doing outdoor stuff, bring old clothes you don’t care about.
I ruined a white sundress on the Kalalau Trail lookout. Still mad about it.

The Three Things Everyone Forgets
Reef-Safe Sunscreen (You Legally Can’t Use Regular Sunscreen)
Hawaii banned sunscreens with oxybenzone and octinoxate back in 2021. Those chemicals kill coral reefs. Now stores in Hawaii can only sell reef-safe sunscreen.
Some counties have even stricter rules. Big Island and parts of Maui only allow mineral sunscreens with zinc oxide or titanium dioxide. No chemical sunscreens at all.
You can buy reef-safe sunscreen when you land but Hawaii prices are brutal. We usually order some before we go. Sun Bum, Blue Lizard, ThinkSport, CeraVe all make good ones.
Real talk: mineral sunscreen is harder to rub in than the chemical stuff you’re used to. You might look a little white for a minute. It fades. The coral reefs are worth it.
Reusable Shopping Bags
Kauai banned plastic bags in 2011. Stores won’t give you plastic bags. They’ll sell you paper ones but they charge for them.
If you’re planning to hit the grocery store at all, bring your own bags. I pack these foldable nylon ones that take up basically no space. We also use them as extra bags for dirty laundry and wet swimsuits on the way home.
Beach Bag
You need a good beach bag with kids. Something big enough for sunscreen, towels, toys, snacks, water bottles, and all the random stuff kids suddenly need at the beach.
Get some wet/dry bags to throw inside so wet swimsuits don’t soak everything.
Beach backpacks work too if you prefer that style.
Stuff for Specific Kauai Activities
Waimea Canyon
Waimea Canyon is called the Grand Canyon of the Pacific. It’s amazing. The drive up has switchbacks.
If anyone in your family gets car sick, bring Dramamine or ginger chews. My youngest can’t do winding roads without turning green.
If you’re just stopping at the lookout points you don’t need much. Maybe some cash for snacks from the vendors.
Going all the way up to Kokee State Park? Bring jackets. It’s actually cold up there. Like need-a-sweatshirt cold.
Boat Tours
Boat tours are huge on Kauai. Na Pali Coast tours, sunset cruises, snorkeling trips.
The wind on a boat tricks you into thinking you’re not getting sunburned. You are. Wear sunscreen and reapply it. Bring lip balm with SPF too.
I’m a big fan of long-sleeve rashguards for boat trips. Protects your skin and you don’t have to keep reapplying sunscreen to your arms.
Check with your tour company about shoes. Some boats are barefoot only, some want you in water shoes or sandals.
Hiking
Kauai has incredible hiking. I wrote a whole hiking packing list but the basics:
Actual hiking shoes or boots. Not flip-flops. I see tourists in flip-flops on trails all the time and it never ends well. My favorite sandals for active kids are here.
Kauai jungle areas have bugs. Bring bug spray.
Sunscreen and a hat even if you think the trail is shady. Sun finds you.
Snorkeling
You can snorkel on your own at beaches or book a snorkeling tour.
You need a swimsuit and rashguard. If you’re going on your own, it’s honestly cheaper to buy a snorkel set than rent one for a week. They sell them everywhere in Kauai too, even at grocery stores.
Fins help but aren’t required. Mask defogger is nice to have.
Best Kauai snorkeling beaches.
Luaus
Kauai luaus are fun. People dress up a little bit.
For guys, khaki shorts or pants with a polo or Aloha shirt.
Women usually wear sundresses, nice pants and a top, or a maxi dress (solid colors or tropical prints both work).
Kids can wear whatever but lots of families do Aloha shirts or dresses for the photos.
Skip heels. Some luaus are on grass and they get muddy if it rains. Which it does. Flats or sandals.
Photo Shoots
More families are booking professional photographers in Kauai and honestly it’s one of my favorite things we do.
The island is gorgeous, you get amazing photos, and I’m actually IN some pictures for once instead of being the one taking them.
Most families dress up a bit. Guys in collared shirts, women and girls in dresses. All white looks really good against Hawaii’s colors. Aloha shirts or dresses work great too.
Get fresh flower leis to wear in your photos. They make everything look more special. Lei Po’o (flower crowns) are beautiful.
Save $20 on your Kauai photo shoot.
What NOT to Pack (Learn from My Mistakes)
Giant hats for photos. I already told you about this. Don’t be like me. If you want a cute hat for photos, buy a foldable one or just buy one in Kauai.
Too many clothes. You’re in Hawaii. You’ll live in your swimsuit and shorts. I always pack too much and end up wearing the same three outfits the whole trip.
Full-size toiletries. TSA rules haven’t changed. That big bottle of shampoo isn’t making it through security. Either bring travel sizes or buy stuff when you land.
Heavy books. Download ebooks or audiobooks on your phone. Books weigh a ton and take up space.
Expensive jewelry. Why would you bring this to the beach? You won’t wear it. Leave it home.
Your whole medicine cabinet. Bring what you actually need (prescriptions, kids’ Tylenol, Benadryl, Dramamine). Skip the rest. You can buy stuff there if you need it.
Quick Answers to Questions Everyone Asks Me
What if I forget something important? You can buy almost everything in Kauai. It’ll just cost more. The only thing that might be tricky is finding your exact prescription medication, so definitely bring those.
Should I pack beach towels? If you’re staying at a resort, they provide them. Vacation rentals usually provide them too but check first. We bring one quick-dry towel per person as backup. Takes up almost no space.
What kind of shoes do I actually need? One pair of athletic shoes or hiking shoes. One pair of water shoes or sturdy sandals for the beach. One pair of flip-flops for the pool. That’s it. You don’t need dress shoes in Kauai.
What if it’s cold at night? Winter (December-March) gets into the 60s at night. Bring a light jacket or sweater. Summer nights are warmer but air conditioning in hotels can be intense. I always bring one long-sleeve option just in case.
Do I need formal clothes? No. Kauai is super casual. The dressiest you’ll get is “resort casual” for a nice restaurant or luau. Sundresses and Aloha shirts. Nobody wears suits or cocktail dresses.
What about those giant straw hats I keep seeing on Instagram? Already covered this. They’re cute in photos but terrible for packing. Your call.
Look, Here’s the Thing
I’ve been going to Kauai since I was 10 years old. My grandma lived there, my mom lives there now. I’m a Certified Hawaii Destination Specialist. I’ve taken my own family over 40 times.
And I still forget stuff every single trip.
Last time it was the ridiculous hat. Time before that I forgot athletic shoes and had to buy some at Costco. Time before that I forgot to pack enough sunscreen and paid $25 for a bottle at the hotel gift shop.
You know what though? Every trip was still amazing. Because Kauai is pretty forgiving.
You can buy almost anything you forget. It’ll just cost more. The stuff that really matters: reef-safe sunscreen (because you literally can’t buy any other kind there). Comfortable walking shoes. Your prescriptions. Reusable bags if you’re planning to shop.
Everything else? You’ll figure it out.
Planning a Kauai trip can feel overwhelming. There’s so much to figure out – where to stay, what to do, what beaches are good for kids, which tours are worth it.
That’s literally why I do personalized travel consultations.
I help families figure all this stuff out so they can actually enjoy their vacation instead of stressing about whether they’re doing it right.
I also share more Hawaii tips on my podcast Hawaii Travel Made Easy and in my Kauai Travel Guide for Families.
But honestly? You’re going to have a great time no matter what you forget to pack.
Kauai has a way of making you forget about everything you’re stressed about. That’s kind of the point.
