The Key West packing list is shorter than most vacations require — but a few items are non-negotiable. Reef-safe sunscreen (heavily encouraged by Florida Keys regulations and required by most snorkel boats). Water shoes for Fort Zachary Taylor and snorkel boats. Polarized sunglasses, since the sun reflects off Key West water with intensity most travelers underestimate. Dramamine for any boat trip longer than 2 hours. A light layer for the surprising winter cold fronts that drop overnight temps to the 50s. And — for travelers visiting in the last week of October — multiple costumes for Fantasy Fest. This guide is the complete 2026 Key West packing list organized by activity type, with the items locals wish every visitor knew, the things NOT to bring, what to buy locally vs from home, and the seasonal variations (winter cold fronts, summer thunderstorms, hurricane season). Written by Key West locals who help visitors with packing questions weekly.
You will find the complete general Key West packing list, dedicated lists for snorkel/dive trips, fishing trips, sunset cruises, family trips with kids, and Fantasy Fest week. Plus the carry-on-only strategy for short trips, what to buy at Publix on arrival, the bug-spray hot zones (mangroves at dusk), the dress codes for Key West restaurants (mostly casual; a few exceptions), and the realities most first-time visitors don’t know.

Quick Universal Key West Packing List

The mandatory items for any Key West trip, regardless of season:
- Reef-safe sunscreen lotion (SPF 30+). Mineral-based — zinc oxide or titanium dioxide. No oxybenzone or octinoxate.

- Insulated water bottle. Refill stations are common.
- Phone charger and waterproof phone case.
- Reef-safe lip balm with SPF.
- Light cardigan or fleece for AC. Restaurants and resorts crank the AC.

- Prescription medications. Easier to bring than refill on the island.

Reef-Safe Sunscreen: The Most Important Item
Florida Keys reef ecosystem is sensitive to common sunscreen ingredients. Most snorkel and dive operators require mineral-based reef-safe sunscreen. The local Key West ordinance banning oxybenzone and octinoxate was state-preempted in 2022, but the conservation reasoning still applies — and most boat operators enforce reef-safe-only policies.
What to look for:
Active ingredients: Zinc oxide (preferably non-nano) or titanium dioxide. NOT oxybenzone, octinoxate, octocrylene, or homosalate.
Form: LOTION ONLY. Spray sunscreens are banned on most snorkel boats — they damage the reef AND make boat decks dangerously slick.
Recommended brands:
- Stream2Sea (locally-developed, certified reef-safe)
- Thinksport (mineral, sport-formulated)
- Raw Elements (heavy zinc, certified reef-safe)
- Badger (mineral, organic)
- All Good (mineral, surf-formulated)
Where to buy in Key West: Every CVS and Publix carries certified reef-safe options. Pricing locally is roughly double mainland pricing — bring from home if you can.

What to Buy Locally vs. Bring From Home

Buy in Key West (cheaper or only available locally):
Beer and wine (no need to fly with).
Snacks, fruit, breakfast items (Publix, 3316 N Roosevelt Boulevard).
Bug spray (CVS, Publix).
Some reef-safe sunscreen (markup vs mainland).
Beach umbrella, sand toys, beach chairs (CVS).
Souvenirs (Old Town shops).
Bring from home (cheaper or specialty):
Prescription medications.
Reef-safe sunscreen (mainland prices half local).
Specialty fishing or dive gear (mask, fins, dive computer).
Preferred sun hat (limited Key West selection).
Costumes for Fantasy Fest (huge price markup locally during festival).
Cuban-style guayabera or other dressier outfit.
Underwater camera or GoPro.
Travel-sized Dramamine.
What NOT to Bring
- Spray sunscreen. Banned on most boats. Damages reef. Slicks decks.
- Oxybenzone or octinoxate sunscreen. Banned by ordinance at boat operators.
- Glass bottles or containers. Banned at most beaches and on all boats.
- Formal wear. Key West dress code is casual. A nice button-down or dress is the dressiest you’ll need.
- Heavy luggage. Old Town is walked, not driven. Hard-sided suitcases are awkward on catamaran trips and brick sidewalks.
- Loud jewelry or valuables. Avoid attracting attention on rentals or beach.
- Bananas (for fishing trips). Old fishermen’s superstition; many captains seriously won’t allow them.
- Heavy winter coats. Even December-January, lightweight layers are sufficient.

Bug Spray Hot Zones
Mosquitoes and no-see-ums are real in Key West, particularly at certain times and locations:
- Dawn and dusk anywhere near mangroves — heaviest bug activity.
- Truman Waterfront at dusk — mangroves nearby.
- Mangrove kayak tours — bring bug spray for the boat ride.
- Fishing trips that include backcountry — bug spray essential.
- Outdoor dining in summer at dusk — many restaurants supply bug repellent at the table.
- Geiger Key, Sugarloaf Key — heavy mosquito areas during summer.
Recommended: Picaridin-based or 30% DEET. Buy locally if you forget — every CVS stocks both.
