Greece is one of the Schengen area countries, which means some travelers will require specific travel insurance. U.S. citizens are not required to obtain a Schengen visa to travel to Greece, but citizens of many other countries are. Note that if you are a resident of the U.S. but not a U.S. citizen, you may need to get a Schengen Visa to travel to Greece. It's essential to review the Schengen Visa travel plans before going to Greece.
