As soon as there is relevant news about Crete regarding Corona I will post it here on the forum.
Greece and Crete will not be open in May, although this is not official yet. Not only the situation in Greece, but also in the home countries of the tourists, determines when Greece will open. Until then there is only hope.
Some hotel owners, like the ones in Sfakia, hope to be able to open in July. Others hope for August or September, and some expect not to open at all this season.
All the best,
