Every island has its own personality, but our starting packing list is almost always the same: sun protection, water gear, something to carry cold drinks, and a few small comfort items that keep everyone from melting down halfway through the day. Some links in this article are Amazon affiliate links, which means we may earn a small commission if you buy through them at no extra cost to you.
The short version: pack for sun, sand, salt water, bugs at dusk, and expensive convenience purchases. We try to bring the boring things from home so we can spend island money on the good stuff.
If you already know your destination, we also have island-specific checked-bag lists for Grand Cayman, Saint Thomas, Saint Martin and Sint Maarten, and Turks and Caicos.
Start with sun protection
The Caribbean sun is not subtle. We pack more sunscreen than feels reasonable, because buying it on island is usually one of those annoying little expenses that could have been avoided.
We also bring at least one hat that can get crushed in a bag without becoming useless. The person who says they do not need a hat is often the person borrowing one by lunch.
Bring your own snorkel setup if you plan to use it more than once
If snorkeling is a one-time maybe, renting can be fine. If you know your family will be in the water most days, we would rather bring our own gear. Fit matters, and it is nice not to spend the first 20 minutes of a beach morning adjusting a leaky mask.
Travel fins are the part we do not skip anymore. They make shore snorkeling feel calmer because you can cover more distance with less effort.
Pack a small cooler plan
We do not need a giant hard cooler on a beach vacation. We do like having a backpack cooler for water, seltzers, fruit, sandwiches, and whatever snacks were supposed to last the whole afternoon but obviously did not.
This is one of the easiest ways to keep a beach day relaxed. Nobody wants to abandon a good parking spot just because everyone suddenly needs cold drinks.
Plan for dusk bugs
Mosquitoes are not usually an all-day problem for us on island trips, but that evening window can be brutal. We keep bug spray in the room and use it before dinner if we are walking, sitting outside, or driving somewhere near mangroves.
We also pack a small anti-itch option. It takes almost no space, and it is exactly the kind of thing nobody wants to shop for after the bites already happen.
Add comfort items only if they match your trip
Beach chairs, pool floats, and underwater cameras are not universal must-packs. They are worth it when they fit the way you travel.
For us, a packable chair makes sense when we are visiting public beaches without guaranteed rentals. Inflatable float hammocks make sense when the water is calm or the condo has a pool. An underwater camera makes sense when snorkeling is part of the trip and we do not want to trust a phone case underwater.
Our bottom line
We pack Caribbean trips around the moments that repeat: sunscreen before breakfast, beach bags in the car, wet gear on the balcony, hungry kids after swimming, and one last walk outside after dinner. If the gear helps those moments go smoother, it earns space. If it only sounds useful in theory, it can stay home.
