(CNN) — Once one of the world's most powerful travel documents, the might of the United States passport has been diminished during the pandemic. With US Covid-19 cases nearing the 31 million mark, some nations continue to view vacationers warily. In the end, it's up to you to decide whether travel to international destinations is a good idea. The health risks are obvious. Nations might change their rules at any time. You may have to adhere to stricter curfews and mask mandates than Americans are used to following. Violations could involve big fines and even jail time. Also, keep this in mind: All air passengers 2 and older must show proof of a negative Covid-19 test that's no more than 72 hours old to enter the United States. That includes US citizens returning from trips to other countries. Meanwhile, new CDC guidance says fully vaccinated people can travel at low risk to themselves but still recommends against it because of rising numbers of coronavirus cases.
What follows is an alphabetical list of countries and territories where it's still possible for US passport holders to go for a vacation:
Set on the Adriatic Sea, Albania remains open. While there's no Covid-19 test requirements or quarantine to enter, you can expect a health screening. More info: US Embassy.
