Celestyal Cruises is to deploy a second ship out of Athens this summer.
The Greek line confirmed it will require guests to provide a negative PCR Covid test taken within 72-hours prior to embarkation of the cruise.
It said it is awaiting further guidance from health authorities as to whether it can waive the requirement for those who have been vaccinated against Covid-19.
Celestyal said its crew will be fully vaccinated and PCR testing will be available on board for all guests if needed, at their cost.
Celestyal Olympia will sail from Celestyal’s dedicated terminal at Lavrion Port & Marina on a seven-night Legendary Archipelago itinerary from June 28 to August 30.
The all-inclusive cruise will call in Thessaloniki, Mykonos, Santorini, Agios Nikolaos (Crete) and Rhodes in Greece and Limassol in Cyprus with prices from £759 per person.
As of August 30, Celestyal Olympia will operate her scheduled three- and four-night Iconic Aegean and Iconic Discovery itineraries from the same port, for the remainder of the season.
Bookings open from Friday, April 9. Celestyal Crystal is already due to sail from the port from May 29.
Greece has announced that, as of mid-May, it will welcome European travellers back as long as visitors provide proof of being vaccinated, or certified to have Covid-19 immunity or a negative PCR test 72-hours prior to departure.
“As the vaccination programme picks up speed across Europe, we are confident that travellers from our key markets will soon be on the move again,” said Leslie Peden, chief commercial officer.
“We are thrilled with the positive progress of the safe and healthy reopening of Greece and cruising in May, building on last year’s successful partial deployment of cruises in Greece. It is not surprising that we are witnessing a strong increase in demand from our European guests as a result.”
