(CNN) — US passport holders have more international travel options now than at any point during the Covid-19 pandemic.
Total US cases are around the 37.3 million mark since the pandemic started. After a promising spring and early summer of declining cases in 2021, new dark clouds have appeared on the horizon.
Still, more of Europe opened up this summer to US leisure travelers, especially the fully vaccinated. And Canada joined the list on August 9.
In the end, it’s up to you to decide whether travel to international destinations is a good idea. The health risks are obvious if you’re not fully vaccinated. Nations might change their rules at any time. You may have to adhere to strict curfews and mask mandates. Violations could involve big fines and even jail time.
If you want expert input into your decision, the US State Department and the Centers for Disease Control and Prevention provide Covid-19 risk assessments by country. Both agencies rate many of the countries open to US travelers at Level 4, the highest risk for Covid-19. Also, remember that all air passengers 2 and older must show proof of a negative Covid-19 test that’s no more than three days old to enter the United States.
List of nations
What follows is an alphabetical list of countries and territories where it’s still possible for US passport holders to go for a vacation. Click the links at the end of each destination for important information on:
— Presenting negative results from Covid-19 tests to enter (including time limits to take the test, types of tests allowed and additional tests upon arrival). — Quarantines (if any) and health screenings. — Possible exemptions from the rules for the fully vaccinated, people recovered from a recent case of Covid-19 or children. — Health insurance requirements, curfews and lockdowns. — Different rules if you’re arriving from a third country vs. the United States.
These are all things you need to research before you book your trip. People testing positive for Covid-19 upon arrival or while visiting can expect to go into quarantine. Rules for land entry may be different.

Recently removed from the open list
The following countries had been allowing US citizens to enter but have closed again or were removed by CNN Travel for other reasons:
— Cambodia: The US Embassy reports the Southeast Asian nation has stopped issuing tourist visas; you can still apply for business-linked visas.
— Chile: It has closed its borders to almost all tourists through at least August 31.
— Ethiopia: CNN Travel has removed because of ongoing warfare in parts of the country.
— Sri Lanka: CNN awaits further information before returning this nation to the “open” list.
This is a curated list and not a full listing. CNN Travel has omitted certain open countries if they had very limited numbers of US travelers before the pandemic; have ongoing or recent armed conflicts, terrorism or rampant crime and unrest; or have entry requirements so extensive and complicated that they put the country out of reach of almost all US citizens. However, you can click here to check for the status and entry requirements of any country or territory in the world you wish to visit.
