Editor’s Note — Coronavirus cases remain in flux across the globe. Health officials caution that travel increases your chances of getting and spreading the Covid-19 virus. Unless you’re fully vaccinated, staying home is the best way to stem transmission. Below is information on what to know if you still plan to travel, current as of July 23.

(CNN) — If you’re planning to travel to the islands of the Caribbean, here’s what you’ll need to know and expect if you want to visit during the Covid-19 pandemic.

The first thing to keep in mind is the Caribbean Sea region consists of 13 independent island nations. There are even more overseas territories. Each of them has its own rules, subject to frequent change.

Some of the islands opened back up to travel in the summer and fall of 2020. Others reopened more recently. Restrictions can vary. Some islands require quarantines, even for vaccinated travelers, while others don’t even request a Covid-19 test. Rules vary depending on your country of origin.

Also remember that hurricane season continues through November 30. Typically, the worst part of the season is mid-August through September. Islands in the southern part of the Caribbean are usually less affected by hurricanes than their more northerly neighbors. Get updates at CNN Weather.

Here’s a roundup on 10 popular destinations that are open. Follow the links provided so you can find out all the crucial details and check for updates before you book a trip:
