This question already has an answer here:

I will eventually end up with so few US dollars when in San Francisco airport, that I won't have to declare them to customs when I arrive at Greece.

Should I convert them to Euros in SF, or in El. Venizelos airport at Athens? Or it's pretty much the same fees in both cases?

    Also pleas explain, because I have no idea how all this works. I think you are suggesting go going to the bank in Greece and give them my US dollars? How else do you think you can exchange dollars to euros? Of course you have to give them your dollars. – deviantfan Sep 10 '16 at 7:05

    How much money do you have? Under 100 bucks the difference is negligible. – JonathanReez Sep 10 '16 at 8:52

    I think this is covered by What is the best method for exchanging dollars for Euros?: that also talks about using cards, but covers cash as well. Basically, so long as you don't change at the airport, it'll be pretty much the same, make sure you change somewhere that's not a captive market – user568458 Sep 10 '16 at 11:44
