Currency

Finland uses the euro. There are exchange bureaus in all bank branches and major hotels; Forex booths in major cities; and at Helsinki–Vantaa Airport. Some large harbor terminals also have exchange bureaus, and international ferries have exchange desks. Local banks and Forex offices usually give the best rates and charge a minimal commission. You can also change back any unused currency (no coins) at no fee with the original receipt. An exchange cart moves through the trains to Russia.
