ATM at the airport?
Is there a cash machine (ATM) at the airport? Does it accept VISA cards?
Yes, there is an ATM at the Grenoble Airport. But I'm not sure about talking a Visa card unless you have a card that has a pin number, i.e. a debit card. If you do have a debit card make sure you won't be paying any excessive fees.
If you don't have a debit card, then look for a Bureaux de change. Many banks and post offices can also change money.
