San Diego Packing List 2026

Must have 6+ months validity from your travel date — airlines and immigration will turn you away without it.

Check requirements for your passport — many countries have visa-on-arrival or eVisa options.

Print a copy AND have it on your phone. Include the emergency phone number.

Printed + digital copies of flights, hotels, and any pre-booked tours.

Some visa-on-arrival counters still require physical photos. Print at CVS, Walgreens, or any pharmacy before you go — takes 10 minutes.

Have some local cash before leaving the airport — not everywhere accepts cards.

Charles Schwab, Wise, or a travel card — foreign transaction fees add up fast.

Laminated card: embassy number, insurance hotline, family contacts. Keep separate from wallet.

Schedule at usps.com/manage/hold-mail.htm — free, takes 2 minutes, holds mail up to 30 days. Overflowing mailbox is a visible signal your home is empty.

Quick-dry, light-colored. Pack roughly 1 per 2 days — laundry is cheap and available.

Doubles as beach and town wear. Avoid cotton — it stays wet forever in humidity.

Required for temples, nicer restaurants, and cooler evenings. Lightweight linen or nylon.

You'll be in the water. A lot. Pack two so one can dry.

Beach cover-up, temple scarf, picnic blanket, emergency towel. Most versatile item you'll pack.

Lightweight, broken-in before you go. Your feet will thank you after 15,000 steps on cobblestones.

Beach, boats, showers at budget guesthouses. Chacos or Tevas hold up far better than cheap flip-flops.

Packable wide-brim hat for all-day sun exposure. Baseball caps don't protect your neck.

Lightweight. You'll want it in air-conditioned rooms which can be arctic.

Packable down jacket as mid-layer. Essential for cold mornings even in temperate climates.

Reef-safe mineral sunscreen for coastal destinations — oxybenzone destroys coral. Apply every 2 hours.

💡 Available locally but reef-safe options are limited and expensive

Bring 2x what you need plus copies of prescriptions. Some medications are controlled or unavailable abroad.

Band-aids, antiseptic wipes, gauze, medical tape, pain relievers. Compact kits fit in a zip-lock.

💡 Available at pharmacies — assemble your own or buy compact kits

Before every meal, after every market, after every tuk-tuk. Non-negotiable.

💡 Available everywhere — buy on arrival

Travel-size toothpaste goes fast. Pack 2 tubes for longer trips.

💡 Available everywhere locally

Solid shampoo bars are great for travel — no liquids restriction, last longer.

💡 Most hotels provide basics — buy locally for longer stays

Get a solid stick or crystal deodorant — gels count as liquids at security.

💡 Available locally but familiar brands may not be found

Pack more solution than you think you need. Daily disposables eliminate solution hassle.

Lips burn too — especially on boats and beaches at altitude.

You will get burned. Have this ready. Keeps in the fridge of your room for maximum relief.

💡 Available at pharmacies and 7-Eleven

Imodium + ORS packets. The ones who don't pack these are the ones who need them most.

💡 Available at pharmacies everywhere

Your navigation, translation, offline maps, and camera all in one. Pack the cable AND a wall adapter.

Big enough to charge your phone 4–5x. Non-negotiable on long travel days and remote islands.

Check the plug type for your destination. A universal adapter works everywhere.

For long flights, buses, and drowning out snoring hostel roommates.

If you want shots better than your phone. Even a compact point-and-shoot is a step up for landscapes.

Cheap insurance. One wave on a boat and your unprotected phone is gone.

Kindle Paperwhite is the standard. Hundreds of books, weeks of battery, beach-readable in sunlight.

Secure your data on public WiFi — essential for hotel, airport, and cafe networks abroad.

Stabilized video from your phone — no editing needed.

Separate from your main luggage for daily exploring. Packable ones fold to nothing.

Insulated bottle keeps water cold for hours in tropical heat. Reduces plastic waste too.

Polarized lenses cut ocean glare and protect your eyes properly. Don't cheap out on this one.

Beach resorts provide towels. Island-hopping boats, waterfalls, and homestays don't.

Game-changer for organization. Your bag stays tidy even after 3 weeks of living out of it.

Island hopping means your stuff rides in open boats. One wave and your unprotected gear is soaked.

For checked baggage and hostel lockers. TSA-approved so security can open without cutting it.

Worth it for anything over 6 hours. Memory foam compressible ones are far better than inflatable.

Markets, beach trips, random purchases. Many countries now charge for plastic bags.

Wet clothes, snacks, liquids for carry-on, sand-proofing electronics. Pack 5–10.

San Diego averages 266 sunny days per year — the most of any major US city. UV index hits 10+ from April through October. Reef-safe sunscreen is required for snorkeling and diving at La Jolla Cove and Cabrillo National Monument. Apply before you reach the beach, not after.

San Diego has a marine layer — coastal fog that rolls in most mornings and evenings from May through August (locals call it "June Gloom"). Even when inland temperatures hit 80°F, beach areas stay 65–70°F until noon. Always bring a light jacket or packable fleece for beach mornings and evening craft beer patios.

San Diego is a walking city — Balboa Park covers 1,200 acres and you will log 8–12 miles on a day there. The Gaslamp Quarter's cobblestone streets and Old Town's uneven terrain make comfortable shoes essential. Flip-flops work for the beach; bring real shoes for everything else.

San Diego is one of America's most eco-conscious cities — plastic water bottles are frowned upon and water quality from the tap is excellent. Stay hydrated (the dry coastal air is deceptively dehydrating) with a reusable bottle. Free water refill stations throughout Balboa Park, the Zoo, and the waterfront.

Rental masks are often scratched or foggy and shared by hundreds of people. Your own costs $25 and lasts years.

💡 Rentable at most dive shops for $3–8/day but quality varies

Travel-size split fins or short blade fins fit in checked luggage. Full-size fins can be rented locally.

💡 Rent locally for $2–5/day — perfectly reasonable

UPF 50+ protection while snorkeling. Reduces sunscreen needed, prevents jellyfish scratches.

Marine park rangers at many sites will turn you away with chemical sunscreen. Zinc oxide is mandatory.

GoPro HERO is the standard. Captures video your phone camera cannot touch underwater.

Break them in for at least 20 miles before your trip. Blisters from new boots on day 1 ruin everything.

Reduces knee impact by 30% on descents. Collapsible carbon poles pack down small.

For pre-dawn summit starts, cave tours, and power outages. 200+ lumen minimum.

Pack more than you think for day hikes. Clif bars, jerky, nuts. Hard to find on trails.

💡 Buy before the hike at local markets or convenience stores

Moleskin on hot spots before blisters form. Carry this in your day bag every hike.

Required at most temples and mosques. Keep a lightweight long-sleeve and pants accessible — not buried in your bag.

You'll remove shoes constantly at temples. Laced boots become frustrating fast.

Cover shoulders on short notice. Many temples loan sarongs but they're often worn and uncomfortable.

💡 Buy one at the first market you visit — cheap and locally made
