Pack cubes by day, not category
For beach trips you'll wear the same 3 things on rotation. One cube per 2 days keeps the suitcase tidy and your bathroom counter clear.

Essentials you'll want
Reef-safe sunscreen (SPF 30+)
Required at many reefs in Mexico, Hawaii, and Thailand. Reef-damaging oxybenzone is banned in several destinations.
Two swimsuits
One always ends up wet when you need it. Rotation also doubles their lifespan.
Quick-dry beach towel
Packs down 4× smaller than a regular towel and dries between morning and afternoon swims.
Waterproof phone pouch
Boats, kayaks, sudden rain — worth the $10. Lanyard versions float.
Aloe vera gel
Buying it at the resort costs 5×. Refrigerate it for instant sunburn relief.
Sun hat + polarized sunglasses
Skin protection plus zero glare on the water. Packable straw or canvas survives the suitcase.
Reef-safe lip balm with SPF
Lips burn first and peel for days. Most people forget this.
Light long-sleeve cover-up (UPF 50)
Best protection on snorkeling boats and 11am–2pm peak sun.
Water shoes or sport sandals
Coral, rocks, hot sand, and sea urchins. Required at many rocky-beach destinations.
Dry bag (10–20L)
Keeps phones, keys, and a change of clothes safe on boat days.
Pro packing tips
Skip jeans
They take 2 days to dry in humidity. Linen and quick-dry shorts win every time, and they pack flatter.
Bring an empty tote
For wet swimwear on travel day home, plus duty-free, market finds, and the inevitable extra bottle of mezcal.
Apply sunscreen 20 minutes before sun
Chemical sunscreens need time to absorb. Reapply every 80 minutes in the water — no matter what the bottle says.
Decant your toiletries
Resort toiletries are mediocre and resort shops are predatory. 100ml silicone bottles fit your real shampoo without leaking.
Leave the white linen for one outfit
Sunscreen + sand + sweat = permanent yellow stains. Save the all-white look for the one dinner photo.

How to pack for a beach week without overpacking
Most people pack like they'll change three times a day. In reality, beach days are simple: swimsuit, cover-up, sandals, sunglasses, sunscreen, water bottle. Plan three categories of outfits — pool/beach by day, casual lunch, and dinner — and pack two of each per week. Laundry is widely available at beach resorts and Airbnbs, and rotating fewer pieces means less wrinkled chaos in your suitcase. Build everything around one consistent color story (sand, navy, white, one accent) so any top works with any bottom.
Sun protection: what actually works
SPF is non-negotiable, but it's the layering that prevents burns. Use a mineral sunscreen (zinc-based) on your face, a spray for arms and legs, and physical barriers — a wide-brim hat, polarized sunglasses, and a UPF rash guard or cover-up — between 11am and 3pm. For coral reefs in Mexico, Hawaii, Palau, and Thailand, oxybenzone and octinoxate are banned. Check the back of the bottle before you fly: if you can't find a non-nano zinc oxide formula, buy one at the destination duty-free.
What not to bring
Skip: hair dryer (almost every property has one), iron, heavy beach towels (resorts provide them and Airbnbs have them), full-size toiletries, bulky novels (Kindle or phone library), more than one pair of dress shoes, and any jewelry you'd be sad to lose. The pool will eat at least one earring per week — leave the real stuff at home.
Frequently asked
How many outfits do I need for a 7-day beach trip?
Plan for 3 swim-day outfits, 3 dinner outfits, and 1 travel outfit. Most beach destinations have laundry, so you can comfortably rotate.
Can I bring sunscreen on a plane?
Yes, in containers under 100ml/3.4oz in your carry-on. Larger bottles go in checked luggage. Aerosol cans have airline-specific limits — check before you fly.
What shoes do I really need for a beach vacation?
Flip-flops, one pair of sandals you can walk in, and sneakers for the airport. That's it. Heels are almost never worn on a beach trip.
Should I bring a beach towel?
Resorts: no — they provide them. Airbnbs and hostels: yes, or at minimum a quick-dry travel towel that packs into a fist.
What's the best bag for a beach day?
A canvas or mesh tote you don't mind getting sandy, plus a small dry bag inside for phone, keys, and cash.
Is reef-safe sunscreen really required?
Legally required in Hawaii, parts of Mexico (Cozumel, Xcaret, Xel-Há), Palau, Bonaire, and Aruba. Strongly encouraged everywhere with coral. Rangers do check.
