The need to self isolate on arrival in Turkey was removed a while ago. But over 65s only supposed to be out from 10-20.00 and everyone supposed to wear masks when out and about. Not when sitting in bars or restaurants though. Neither of them seem to be adhered to by a lot of people, but those are the rules so up to each individual. Covid19 insurance not mandatory but can be purchased at the airport I believe, highest cost is 23 euros for 7,000 euros cover. Posted on here, I think unde Cali s holidays in general section.
