Where can Americans travel in Europe? Find out here

While the news of Europe's reopening to American travelers is causing excitement among travel advisors and their clients, each country is able to set slightly different entry requirements, causing complications for would-be travelers.

To add to the complications, the EU signaled a move to reinstate travel restrictions barring nonessential travel from the U.S. and imposing quarantine and testing on U.S. travelers arriving into the region, according to a Reuters report on Aug. 27. However, the restrictions recommended by the European Council will not be mandatory among EU-member states.

A Covid test is still required of any traveler entering, or re-entering, the U.S.
