The Mediterranean country previously lifted restrictions for Israelis who had been vaccinated and promised to cancel obligatory quarantines for many other nations over the course of April.
Athens announced on Monday that travellers from multiple countries who have a negative PCR test or have been vaccinated against the coronavirus can enter Greece without quarantining.
The list includes European Union member states and countries in the Schengen Agreement, the United States, United Kingdom, Serbia, Israel and the United Arab Emirates. Their nationals will be allowed to travel to Greece via the airports of Athens, Thessaloniki, Heraklion, Chania, Rhodes, Kos, Mykonos, Santorini, and Corfu, as well as two border crossings.
However, all of the previous travel restrictions for international and domestic flights will remain in place until 26 April.
Before the restrictions were partially lifted earlier this month, all foreigners arriving in Greece had to provide a negative PCR test and then quarantine for seven days.
So far, Greece has registered only 315,000 coronavirus cases and around 9,400 deaths from the disease.
