Cuba requires health Insurance
When going to Cuba you will be required to have medical insurance. NOTE – your regular health insurance that you have in the United States will not suffice. Cuba requires non-US medical insurance. If you don’t have this, there are agents who will sell you a temporary policy upon arrival at the Havana airport for roughly $3 USD per day. However, when flying direct from the US, the price of your flight should include a Cuban health insurance policy. I confirmed this is true with American Airlines.
Best Bet is Buy Travelers Insurance
If you are arriving by boat/yacht then you need to make sure you have Travelers Insurance. I purchased the Travel Guard Insurance even though I am flying, so that I would have all the benefits of this policy including hurricane coverage, terrorist coverage and Medical Evacuation benefits.
