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 January 5.
(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.
Each of them has its own rules, subject to frequent change. Some have put up travel bans or changed their rules because of the recent Omicron variant.
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.
Here's a roundup of key highlights on nine popular Caribbean destinations. There is also a link to keep track of the most recent risk level for each destination from the US Centers for Disease Control and Prevention.
Aruba is known for its white beaches and colorful buildings in the capital city of Oranjestad.
What's on offer: Days are usually dry and sunny. Arikok National Park features caves, desert landscapes and giant lizards. Wide beaches bordering clear jade water are the big draw.
Who can go? As of January 5, citizens of all countries can enter with the exception of seven nations in southern Africa: Botswana, Eswatini, Lesotho, Mozambique, Namibia, South Africa and Zimbabwe.
Entry requirements: These vary depending on your country of departure.
Aruba has introduced a list of very high-risk countries, all of them in Europe, from which arrivals must adhere to stricter testing than other visitors and must test no more than one day before their departure for Aruba. These visitors won't have the option of test upon arrival.
People coming from high-risk countries, including the United States and Canada, must take a molecular Covid-19 test within two days of their departure to Aruba and won't have the option to test upon arrival.
Aruba visitors insurance, in case you test positive for Covid-19, is mandatory. No quarantine is in place. Travelers who test positive for Covid-19 are required to stay in mandatory isolation, however.
US CDC travel advisory: Level 4 (very high). Avoid travel to Aruba.
You'll find Bimini Big Game Club and Marina on North Bimini, which is off the coast from Miami, Florida.
