If you are planning to visit the island of Anguilla, you must be vaccinated at least three weeks before the date of arrival. Negative PCR tests too are required; one test should be done five days before your departure date and the other should be done on arrival. Anyone applying for permission to visit the Caribbean's from outside the islands must apply online for permission to enter. Visitors who book stays at resorts, villas, or hotels will not be asked to go into quarantine; instead, they must do a PCR once more on the fourth day of their stay in the nation. For easy Caribbean Island flights, you can check out the scheduled regional airlines such as interCaribbean Airways, which offer routes to over 20 cities within the archipelago.
