Entry to Estonia for foreign nationals is still restricted.
The borders of Estonia have been reopened from 1 June to passengers arriving from European countries. Estonia will admit people with no symptoms arriving from the European Union, the members of the Schengen area or the United Kingdom of Great Britain and Northern Ireland.
The compulsory self-isolation for people arriving in Estonia depends on whether the relative coronavirus infection rate in their country of departure where they have spent at least 14 days before departure is above 16. This means that no more than 16 people per 100 000 inhabitants are infected in the passenger’s country of departure in the past 14 days. Anyone arriving in Estonia from a country with a higher infection rate (including Romania and Bulgaria) must self-isolate for two weeks on arrival.
A foreign national who is in Estonia for transit to reach their home country can travel through Estonia provided they have no symptoms of the disease.
