HI K99, I have just returned from turkey (been twice now-spectacular!) anyway even though they are not in EU they will infact take Euro's as we took some incase we visited rhodes, the currency in Turkey is Turkish lira but absolutley eveyone will except english currency, it pays you to have some, you often get better bargaining power with it, and if you do take english money and you want to exchange it there we found the exchange rates pretty good, have a great time!!
