Snorkel gear & local food
What to Pack
Clothing
Swimsuits (2–3)
You'll be in the water daily. Having multiple means one is always dry.
Rash guard or swim shirt
UV protection for snorkeling, surfing, and long beach days. More effective than sunscreen for extended water time.
Lightweight shorts and t-shirts
The island is casual. Linen or tech fabric shorts dry fast and pack light.
One nicer outfit
For a sunset dinner or luau. Hawaii dining is casual — a sundress or aloha shirt is enough.
Light layer or hoodie
For air-conditioned restaurants, evening trade winds, and the flight home. One is enough.
Flip-flops and sandals
For beach, town, and casual meals. Not for hiking.
Trail shoes or sneakers
Essential if you plan to hike Diamond Head, Koko Head, or any trail. Do not hike in flip-flops.
Water shoes (optional)
Useful for Hanauma Bay's rocky entry, snorkeling, or tide pools.
Sun & Beach
Reef-safe sunscreen (SPF 50+)
Hawaii law requires reef-safe sunscreen (no oxybenzone or octinoxate). Bring from home — it's significantly cheaper than buying in Waikiki.
Sunglasses
UV protection is essential. The Hawaiian sun reflects off water intensely.
Wide-brim hat
For hiking and long beach days. Prevents heat exhaustion on exposed trails.
Beach bag or dry bag
A simple tote works for the beach. A dry bag is useful for snorkeling or kayaking.
Snorkel gear (optional)
Snorkel sets are available to rent at Hanauma Bay and most activity desks. Only bring your own if you go frequently or have a preferred fit.
Health & Safety
Insect repellent
Mosquitoes are present in rainforest and valley areas (Manoa Falls, Ho'omaluhia). DEET or picaridin works best.
After-sun lotion
Even careful visitors get some sun. Aloe vera gel soothes and heals fast.
Prescription medications
Bring more than you need — refilling prescriptions on the island takes time.
Basic first aid kit
Band-aids, antiseptic wipes, and blister pads for hikes. Small enough to not matter.
Reusable water bottle
Critical for hiking. 1 liter minimum per person per trail. Refill at hotels and restaurants.
Tech & Documents
Waterproof phone case or pouch
For kayaking, snorkeling, and beach days. Your phone is your camera — protect it.
Portable charger / power bank
Long days of navigation, photos, and reservations drain batteries fast.
Downloaded offline maps
Some North Shore and Windward Coast roads have poor cell coverage. Download your route in Google Maps before you go.
Travel insurance info
Print or screenshot your policy details, especially emergency evacuation coverage.
Hanauma Bay reservation confirmation
Print or screenshot it. Reservations are required and they check at the gate.
Diamond Head ticket confirmation
Booking at hawaii.goingtocamp.com is required. Have it ready on your phone.
What to Leave Home
Heavy jeans
You won't wear them. Too hot, too heavy to pack. Leave them home.
Formal clothes
Hawaii's fanciest restaurants accept aloha shirts and sundresses. Nothing in Waikiki requires a blazer.
Umbrella
Oahu's rain showers last 10 minutes. Most visitors never use an umbrella — just wait it out.
Non-reef-safe sunscreen
It's illegal in Hawaii and damages the reefs you're going to snorkel. Don't bring it.
Multiple pairs of shoes
One pair of flip-flops + one pair of sneakers/trail shoes covers everything on Oahu.
Lots of cash
Oahu is card-friendly everywhere. Keep $50–$100 cash for farmers markets, food trucks, and tips.
Frequently Asked Questions
What should I pack for a week in Hawaii?
For a 7-day Oahu trip: 3 swimsuits, 5–6 lightweight outfits, one nicer dinner outfit, trail shoes, flip-flops, reef-safe sunscreen, sunglasses, a hat, a light layer for evenings, and a reusable water bottle. Pack light — you'll want luggage space for souvenirs and the island heat means you'll wear less than you think.
Do I need reef-safe sunscreen in Hawaii?
Yes — Hawaii law bans sunscreens containing oxybenzone and octinoxate, which damage coral reefs. Look for mineral sunscreen with zinc oxide or titanium dioxide. Brands like Raw Elements, Sun Bum Mineral, and Thinksport are widely available and reef-safe. Bring from home — reef-safe sunscreen in Waikiki costs 2–3x more.
Should I bring or rent snorkel gear in Hawaii?
Rent it. Quality snorkel sets are available at Hanauma Bay (included with entry), and rental shops in Waikiki and Kailua offer full sets for $10–$20/day. Unless you snorkel regularly and own a preferred set, renting is more practical than packing bulky fins.
What shoes do I need for Oahu?
Two pairs covers everything: flip-flops or sandals for beach and casual meals, and a pair of sneakers or trail shoes for hiking. Do not attempt Diamond Head, Koko Head, or any trail in flip-flops — the terrain is uneven and steep.
What can I buy when I get to Hawaii?
Almost everything, but expect to pay more. Sunscreen, beach gear, and drugstore items cost 30–50% more in Waikiki than on the mainland. The one exception: local food. Plate lunches, poke, and farmers market produce are significantly cheaper than you'd expect and worth every dollar.
Do I need to bring cash to Oahu?
Not much. Credit cards are accepted nearly everywhere, including food trucks. Keep $50–$100 cash for farmers markets, small food stands on the North Shore, tips, and the occasional cash-only spot. Most ATMs in Waikiki charge $3–$5 fees — withdraw what you need in one trip.
