What to Pack for Cozumel

A day ashore is not a holiday, and the list is shorter.

You are back aboard by evening. That removes most of what a packing list usually argues about and leaves a handful of things that genuinely decide how the day goes: sun cover, water, cash in small denominations, comfortable shoes for paving and uneven stone, and whatever you need to get back through the terminal.

The item people forget is not an item.

The general travel advice for this country asks every traveler to get appropriate travel insurance, and to check it covers all their planned activities. On this island that second clause carries more weight than usual, because the activity most people come for is in the water. If you intend to get in it, the cover has to say so before you sail, not after.

The same advice is direct about what that activity involves. For adventure sports including scuba diving it states that equipment may not meet UK safety and insurance standards, and that British nationals taking part have been injured and in some cases killed. It asks that the company you use is reputable, takes safety precautions, uses up to date equipment and is fully licensed and insured. Those are the four things to ask about before you hand over money, and they are worth asking whatever passport you hold. If you plan to snorkel or dive, read the safety guide first: it carries this in full.

The water itself.

The advice notes that sea conditions can be unpredictable and that some beaches are unpatrolled, and asks visitors to follow coastguard and local authority guidance on whether it is safe to swim. That is worth packing in the sense that matters: a willingness to not get in.

What this page does not list.

No seasonal clothing guidance, because this register publishes no temperature for this island. The weather guide explains that absence. For a full country-level list, including what changes if you are traveling inland or staying longer, the Mexico packing list is the better page.
