You should get travel insurance before flying out
Before flying to Bermuda without travel medical insurance, everyone should consider twice. Bermuda's medical costs appear to be the second highest in the world, often exceeding those in the United States! Most, if not all, American and British medical insurance companies will not cover you if something goes wrong while you're on the island, so plan ahead of time.
Nobody expects something to go wrong (and ideally it won't), but accidents do happen, and you want to be covered when you need it the most, especially in a place like Bermuda where medical costs may be astronomical.
Because most domestic health insurance does not cover travel outside of the United States, travelers to Bermuda must purchase travel insurance. Applicants can begin the Travel Authorization process 48 hours before their trip. Bermuda will require all tourists aged 2 and up to have a negative PCR test result obtained within four days of arrival starting in July 2021. This is definitely among Things About Bermuda You Should Know before travelling to this country.
