Travellers to Greece face growing anti-Covid measures despite the country previously having one of the best records in Europe on handling the pandemic while restarting travel and tourism.
Greek health authorities introduced new Covid-safety measures on the island of Mykonos and in the resort of Halkidiki on Wednesday
The restrictions, which came into force on Friday August 21, include a mandatory requirement to wear face masks outside and a maximum limit of four people per table at restaurants or six if family members.
Private and public gatherings are limited to nine and parties, religious processions, festivals and open-air markets are banned.
The restrictions will initially apply to the end of August.
There is already a midnight curfew on bars in Mykonos and on bars and restaurants in Halkidiki.
Greek travel news site GTP reported the authorities also launched random Covid-19 tests on arriving ferry passengers at the port of Piraeus this week.
Separately, travellers to Greece from Norway, Finland and Estonia will be required to self-isolate on their return following a rise in Covid-19 infections.
Norway announced 14-day self-isolation requirements on Wednesday for travellers from Greece as well as from the UK, Ireland, and Austria. The restrictions kick in from Saturday August 22. Norway already requires travellers arriving from France, Spain, Poland, and Switzerland to self-isolate.
Finland has advised against all but essential travel to Greece as well as Malta, Germany, Cyprus and a number of other EU states from Monday August 24 and will require arrivals from these countries to quarantine for 10 days.
Tui announced the cancellation of holidays from Finland to Greece in line with the decision.
