First of all, please note that here we will be talking about destinations open for tourism. Many countries are open for citizens and non-citizens traveling with permits, but not many have opened for tourists. So, please choose your vacation destination this summer carefully!
The following countries are open to US tourists without any restrictions:
Albania, Belarus, Cuba, Dominican Republic, Egypt, Kiribati, Kosovo, Mexico, North Macedonia, Palau, Portugal, Serbia, Slovenia, Saint Vincent and the Grenadines, Tanzania, Turkey, Ukraine.
Please check your destination country's restrictions before traveling! Most of them still require you to complete a health form, and some are asking tourists to quarantine for 14 days.
These countries might require medical information or a negative COVID-19 test:
Antigua and Barbuda, Bahamas, Cambodia, Jamaica, Northern Mariana Isl., Puerto Rico, Rwanda, St. Lucia, St. Maarten.
The situation is even better for EU citizens - most of the European Union countries have opened their borders for domestic travel.
