Honolulu & Maui Hawaii Travel Checklist: What to Pack & Plan

Affiliate disclosure: I may earn from links and buttons in this guide — they are optional shortcuts for booking flights, car rental, and tours.

I’m packing for a two-island trip and feeling that familiar mix of excitement and last-minute doubt. I want my first day to click: no missing gear, no frantic runs to find reef-safe sunscreen.

My aim is simple. This is a practical, not-overpacked plan that matches outfits and bookings with activities. I’ll show capsule outfits, beach gear, and quick notes on microclimates so I’m ready whether I’m wandering the easy beachfront or chasing a ridge trail.

For quick reference I link a full packing guide and smart tips here: complete packing checklist and a practical trip primer here: island travel tips. Later I promise two tables — capsule outfits and activity-to-gear matches — so I pack smarter, not bigger.

I build my bag around the scenes I expect: easy city meals and ocean naps for one island, sunrise drives and trailheads for the other.

Waikīkī is walkable, so I favor casual city outfits, a day tote, and shoes for strolling. I pack lighter dress options for dinners near the shore.

On the other island I expect long drives, hairpin curves, and trailheads. That means extra layers, hiking shoes, and a small day pack for hikes and viewpoints.

Temperatures can swing by about 15°F from ocean level (makai) up to mountain (mauka). I feel cooler at higher elevation and bring a warm layer for mornings.

Windward sides tend to be wetter than leeward. Forecasts can lie if you only check one shore. I always include a light jacket that packs small for sudden showers and breezy overlooks.

Mini checklist:

• Pack for two moods: city casual + adventure casual.
• Include a packable layer and a small rain jacket in the day bag.

I lock in flights and major reservations first so my trip starts smooth, not frazzled. That means flights, lodging, and any limited‑seat tours go on my calendar right away.

I aim for morning arrivals so check-in, groceries, and a quick beach walk fit my first day. Early flights also reduce risk of missed connections and give me more time if luggage is slow.

For short hops I travel with a small suitcase or carry bag when I can. Lighter packing eases overhead-bin stress and avoids unexpected weight fees on smaller planes.

For wide exploration I book a rental car early. A rental unlocks the Road to Hāna, Haleakalā sunrise, and remote trailheads that rideshares rarely serve.

If I expect only short drives, I compare rideshare and shuttles. But I note rentals sell out fast, so I reserve as soon as lodging is set.

I don’t hunt for island‑to‑island trains. Transit options are mostly cars, shuttles, and ride apps, so I plan ground travel around those choices.

For inspiration on activities and to match bookings with gear, I check a curated list of the best things to do so my packing and timing line up with the days I’ve reserved.

Before I zip my bag I run every item through a quick stress test: will it earn its place or just take space? That simple filter keeps my suitcase light and useful. I rely on packing cubes and a “buy-locally” mindset so I carry only core items.

My stress-test rule: if I can grab it easily in Waikīkī or Kahului, it doesn’t get prime real estate in my carry.

I prioritize items with multiple uses and avoid duplicates. Packing cubes let me compress and find gear fast. Laundry options at resorts or quick hand-washing fix most overpacking fears.

• Documents & meds — non-negotiable for peace of mind.
• Phone protection + waterproof case for beach days.
• Reef-safe sunscreen and a hat — sun protection earns space.
• One warm layer and one pair of reliable walking shoes.

ABC Stores in Waikīkī offer quick replacements. Costco in Oʻahu and on the island with Kahului stocks larger items and snacks. For a sample itinerary and gear matching, I also check this perfect itinerary guide.

If you only pack 10 things, pack these: ID, meds, phone charger, sunscreen, hat, swimwear, walking shoes, light jacket, waterproof phone case, and a small first-aid kit.

I keep my documents in one easy system so I don’t waste the first morning hunting for confirmations. It saves time at the airport and keeps the first day calm.

My single source of truth: a notes app folder, an email label for confirmations, and one small physical pouch. That trio means I never hunt for a boarding pass or hotel number.

• Exact admin items I gather: ID/passport, hotel reservations, flight confirmations, excursion tickets, car rental info, and a rough itinerary.
• I save screenshots offline so a weak airport or beach connection won’t block check-in.

I buy insurance that covers medical, delays, and rental car issues. I store policy numbers in my notes folder and keep a printed copy in the pouch. Emergency contacts are on my phone home screen and on paper inside the pouch.

I carry one card and small cash on me, the rest locked in the hotel safe. For beach days I move just the essentials into my day bag: ID, one card, cash, and a waterproof phone pouch.

Mini checklist (copy/paste): ID/passport, flight confirmations, hotel reservations, car rental details, insurance policy number, emergency contacts, one card + small cash.

I choose clothes that travel light, resist wrinkles, and still look pulled together after a long day outside. That rule keeps packing simple and makes outfit choices easy each morning.

My daytime uniform is breathable tops, a couple of tanks, and two pairs of shorts. I add one or two easy dresses that don’t need ironing.

Quick-dry fabrics mean I can rinse and re-wear if laundry time is tight.

For dinner I pack one simple dress or linen pants with an aloha shirt and chinos. It’s polished without feeling formal.

For a luau I pick an aloha shirt or a flowy sundress plus flat sandals that won’t sink in grass or sand.

Bring a lightweight cover-up for breezy evenings.

Haleakalā mornings can be very cold and windy. I bring a warm top layer, long pants, and a packable jacket for wind protection.

Laundry reality: With quick-dry pieces I wash a few items in the sink and wear them again. This cuts the total number of clothes I need.

For more timing and prep tips, I use a concise guide here: island travel tips and timing.

For easy beach days I keep a small, reliable kit that covers sun, snacks, and quick dips. I pack with the goal of staying longer on the sand and stressing less about missing items.

I bring two swimsuits so one can dry while the other is ready. Multiple dips, snorkel sessions, and quick changes mean a backup is low bulk and high value.

A sarong becomes a skirt, a beach blanket, a quick privacy wrap, or a light cover. It saves space and replaces heavier items.

For city beaches I carry a lighter bag with sunscreen, wallet, and a bottle. For long coastal days I add snacks, a collapsible cooler, and an extra layer for wind.

A sand‑resistant towel is lightweight and packs small — perfect if I prefer my own towel over hotel options.

I use an insulated water bottle, refill at grocery stops, and bring easy snacks so I skip resort prices. Local stores sell reusable bags and coolers if I forget something.

• Mini screenshot checklist: two swimsuits, sarong, sand‑resistant towel, reef‑safe sunscreen, reusable water bottle, sunglasses, small cooler (optional).

I treat sun gear as essentials, not extras—trade winds can hide how strong the rays are, and I don’t want a surprise burn after a long boat or snorkeling session.

Reef-safe sunscreen: I choose mineral or reef-conscious formulas labeled oxybenzone- and octinoxate-free. For beach and water activities I reapply every 80–90 minutes, or immediately after toweling off, swimming, or heavy sweating. I keep a small tube in my day bag and a larger bottle in my luggage.

Sun hat vs. baseball cap: A wide-brim sun hat gives better ear and neck protection, but wind can turn it into a chase. I pack a lightweight sun hat with a chin strap or a packable bucket hat. If I expect wind, a low-profile baseball cap plus a neck gaiter covers ears better without losing the hat.

Polarized sunglasses cut glare and make water colors pop for snorkeling and boat days. I pick polarized lenses rated for UV400 and stash a microfibre pouch in my top pocket so they stay scratch-free.

My tiny, often-forgotten item is SPF lip balm. I keep one in my day bag and one in my pocket. It’s a quick win for added sun protection.

Rash guard shirts are my go-to on surf lessons and long snorkeling sessions. They reduce sun exposure and cut down on how often I need to reapply sunscreen, which helps both my skin and sensitive marine life.

• Quick top-pocket checklist: reef-safe sunscreen, sun hat, polarized sunglasses, SPF lip balm, rash guard shirt, phone case for protection from sand and saltwater.
• Reapply sunscreen every 80–90 minutes in water, and after towel-drying.

My rule for shoes is simple: versatile pairs that match most activities. I aim for no more than three pairs because most days are beach plus casual walking.

Flip-flops or sandals are my go-to for the sand and quick errands. I wear them at the beach and around shops. They pack flat and save suitcase space.

I bring one comfortable pair of walking shoes for city days and long promenades. Choose breathable, cushioned sneakers you can wear all day without blisters.

If I plan serious hiking, I add hiking boots or trail sneakers. They offer ankle support and grip for rough trails. Otherwise, leave them at home to save weight.

Water shoes protect feet on coral, lava rock, and slippery beach entries. They give better grip and cut the chance of cuts. For waterfall pools and rocky shorelines I always bring them.

• No more than three pairs: sandals, walking shoes, and water or hiking shoes if needed.
• Socks only if I’m hiking or doing cool, early-morning crater visits.
• Decision guide: Road to Hāna + waterfalls = bring water shoes; resort-only beach days = skip hiking boots.

Even on sunny mornings, I pack a slim rain layer because coastal winds can bring fast-moving squalls. Quick rain can soak a day bag and gear, so a tiny plan saves the day.

My pick: a packable rain jacket wins for breathability and wind resistance. It folds small and clips to a backpack.

For heavy spray near waterfalls, a poncho covers more and fits over a daypack. I choose the jacket for hikes and the poncho for quick stops.

A compact umbrella lives in my day bag for short walks between shops and cafes. It’s handy when the wind is light and showers are brief.

Dry bag essentials: phone, wallet, hotel key card, and a small towel. I also tuck in a spare pair of socks for wet trails.

• Waterfall day mini checklist: extra socks, dry bag, rain jacket, traction shoes.
• Bring a phone case or waterproof pouch for quick dips and boat days.
• Safety note: wet lava rock and muddy trails are slippery—choose good soles and move slowly.

Good snorkeling days start with gear that fits and a plan that respects the reef. I balance space, comfort, and safety so every boat or shore session feels easy.

I rent if I’m island-hopping — it saves suitcase space and I can swap sizes. If I snorkel daily, I pack a trusted mask and fins for comfort and cleaner photos.

I bring a GoPro or small underwater camera for reliable footage. My phone stays backup-only unless it’s in a certified waterproof case and on a flotation strap.

My must-haves: fitted mask, defog, comfortable fins, rash guard, reef-safe sunscreen, waterproof phone case + flotation strap.

• Keep a few feet from coral; never stand on it.
• Move slowly, respect wildlife, reapply sunscreen on land.

Trail choices change my bag: stairs, mud, or summit wind—each needs a slightly different kit.

My simple daypack list fits three hike types:

• Diamond Head (sun + stairs): refillable water bottle, light sun protection, hat, and good grip on stairs.
• Rainforest trails (mud + bugs): traction shoes, small first-aid, rain jacket, and insect spray for shaded sections.
• Haleakalā (cold + wind): warm base layer, wind-blocking jacket, long pants, and closed-toe shoes.

I reach for bug spray after a rain or on damp, shaded paths. Dense vegetation and puddles mean more insects, so I apply before stepping into the forest.

I layer: a warm mid-layer, a windproof jacket, long pants, and sturdy closed-toe shoes. Gloves and a beanie help for bitter summit wind.

I only bring poles if they travel in checked baggage. That avoids carry-on hassles and lets me protect the tips with a sleeve or wrap.

Quick reminder: if a sunrise requires reservations, lock the time early so my gear and day schedule match the plan.

My tech bag is as intentional as my clothing — small, reliable, and ready for long days of photos and hikes.

Chargers, power bank, and cords: I bring one wall charger with multiple ports, a compact power bank, a multi-cord (USB-C, Lightning, micro‑USB), and one spare cable. That spare cable is my peace-of-mind item when outlets are scarce in hotel lobbies or shared chargers vanish at cafes.

Most of my memories start on my phone, so I treat it like my primary camera and protect it accordingly. I use a waterproof phone case, a wrist/neck strap for rough shorelines, and a small dry bag for boat days.

Practical habit: leave the phone in the dry bag during snorkel swims and clip the strap when I’m on wet, rocky shorelines. I carry a compact camera only for planned shoots or low-light scenes.

I pack a wireless headphone adapter for older plane entertainment systems and noise-cancelling earbuds for naps. It’s a tiny upgrade that makes flights calmer and keeps my main charger free for the long days ahead.

I use AirTag-style trackers in my checked suitcase and tucked into my day bag. That double placement covers both the bag I carry and the luggage in the hold during island hops, so I can watch location updates during connections.

• Core charging kit: wall charger (multi-port), power bank, multi-cord, spare cable.
• Photo safety: waterproof case, strap, dry bag, small camera for low light.
• Comfort: wireless headphone adapter, earbuds.
• Security: AirTag-style tracker in suitcase and day bag.

Quick note: organized, minimal tech makes island-hopping and short flights smoother. A tidy charging pouch and one realistic image on my phone (power bank, cords, AirTag, waterproof pouch on a hotel desk) remind me I’m ready for the next leg.

My toiletry strategy is simple and repeatable. I decant liquids into reusable travel bottles and keep the same clear pouch so TSA checks and airport transitions stay fast.

I bring a few small bottles: shampoo, sunscreen, and after-sun gel. Keeping them consistent means fewer forgotten items and less repacking at the hotel.

Hard rule: prescription meds always go in my carry-on. If luggage is delayed, my day won’t be derailed and I still have critical doses and rescue inhalers.

• Sunburn relief (aloe gel) and moisturizer for wind and salt exposure.
• Headache meds, motion sickness tablets for boat days, and blister pads for hikes.
• Small first-aid: bandages, antiseptic wipes, tweezers, and a compact pain reliever.

I tuck a travel hand sanitizer in my day bag for snack stops and touchpoints. Salt, sun, and wind dry skin fast, so I pack a light moisturizer and a soothing after-sun.

Micro-checklist for active days: blister kit, electrolyte packets, bandaids. For more island travel tips see island travel tips.

I treat family add-ons as an optional pocket of preparedness: small, light, and easy to pull out when needed. This section is a quick, copy/paste list for anyone planning with children so you don’t hunt elsewhere.

I bring a properly sized puddle‑jumper or life jacket when a child isn’t a confident swimmer. Sizes and stock can be limited on the island, so I prefer packing the right fit rather than hoping to find one locally.

• Downloaded shows and movies for offline viewing.
• Small toys, coloring pads, and sticker books.
• Kid headphones and a compact charger.

I pack at least one extra swimsuit and a quick‑dry top per child. Wet gear dries fast and keeps the next activity fun.

Family admin callout: label water bottles, tuck a small thermometer and child pain relief in the carry, and keep snacks within reach for transit days.

I map activities by day so my bag matches the rhythm of each outing. That makes mornings simpler and keeps my carry compact.

I mix Waikīkī beach lounging with museum stops, shopping corridors, and cultural attractions. For those days I favor light shoes, a breathable top, sunscreen, and a small camera or phone in a waterproof pouch.

Road to Hāna day trips, waterfalls, coastal trails, and Haleakalā sunrise shape my packing. A rental car makes these realistic, so I add a daypack, warm mid-layer, sturdy shoes, and plenty of water.

For a luau I bring a light layer, phone protection, a small wallet, and comfortable shoes for grass seating. A compact rain jacket fits if the night turns breezy.

My water days need quick extras: reef-safe sunscreen, rash guard, water shoes, and a waterproof camera or case. I either rent bulky gear or pack a trusted mask and camera if I’ll be in the water often.

For a concise multi-day gear match and timing, I also reference a practical itinerary guide: perfect itinerary guide.

My arrival routine is simple: check in, stash my bag, and grab a few essentials so the rest of the week feels effortless.

• Waikiki Market — great for prepared meals and fresh produce near the International Marketplace (open daily 6am–10pm).
• Food Pantry Eaton Square — handy if I’m staying near Hilton Hawaiian Village; fast for basics.
• Old Country Market — another easy stop for snacks, drinks, and small supplies.

Must-buy items: large supply of water, grab-and-go breakfasts, beach snacks, and reef-safe sunscreen if I’m low.

I bring a sturdy reusable bag that doubles as a beach tote and a backup for souvenirs. It saves plastic and frees my hands for a cooler or a fresh bottle of water.

Mini hotel-room setup: refill water bottles, pack tomorrow’s beach bag, and charge devices overnight. I skip bulky snacks while packing light — Waikīkī makes restocking easy.

I close my suitcase with intent: essentials in place and a little space reserved for finds. I use packing cubes so gear stays tidy and flexible if I buy a shirt or a snack at a local market.

Final pre-zip sweep — make sure your documents, meds, chargers, sun protection, swim kit, one warm layer, and your day-one outfit are where you can reach them. Seal liquids and keep critical things in your carry-on.

Realistic image suggestion: “Half-zipped suitcase with a little empty space and a folded aloha shirt waiting on top.”
