Effective today until August 31:

Indoor restaurants and entertainment places are open only to fully vaccinated or former covid patients (had Covid more than a month ago but less than 6 months ago).

Outdoors restaurants, cafes etc will be designated vaccinated only or mixed (by the venue owner), with different rules and checks.

Minors under 18 can also enter the restricted to vaccinated places with a negative self test verification submitted by a parent on this site: https://self-testing.gov.gr/ (not sure about non Greek speakers though). Test must be within 24 hours from entry to place.

The major announcement is that even outdoors clubs, concerts, etc are only open to vaccinated or those who had covid in the last 6 months. Thank God! This means no outdoor clubbing in the Islands unless you are vaccinated.
