As you know Greece is in the Eurozone and its official currency is the Euro €. If you are travelling from a country of the eurozone (i.e.Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain) you don’t have to change your money.
If you are travelling from another country outside the eurozone, you will need to convert your cash into Euro €.
