As of 26 August, guests aged 12 years and above must continue to be fully vaccinated including proof of a booster (if their original vaccine course was completed more than 270 days prior to embarkation).  

All guests are required to have a certified negative Covid antigen test taken no more than 48 hours prior to embarkation or a negative PCR test taken no more than 72 hours prior to embarkation, as opposed to the earlier requirement of the test being taken 24 hours prior to embarkation.

Those recently recovered from Covid can provide a doctor’s note supplemented with the positive test result corresponding to the date when the guest was diagnosed positive and the negative test result corresponding to the date of recovery.  

Masks, which were previously mandated in all indoor areas, are no longer required but instead highly recommended for indoor areas and outdoors when in large crowds.

"In accordance with updated guidelines from the European Healthy Gateways, CLIA and Greek health authorities, we are pleased to announce the further relaxation of our health protocols,” said Celestyal Cruises chief commercial officer Leslie Peden.

"The more flexible requirements provide our guests with the option of testing prior to departing for Greece as well as more flexibility when it comes to masking onboard."
