The currency used in Turkey is the Lira. We recommend not attempting to purchase the local currency before your trip, as you will be able to use US dollars for most of your purchases! We suggest bringing approximately $250 USD per person in small bills for spending on things like drinks, water on the bus, small souvenirs, tips over and above the standard, prepaid tips for waitstaff, housekeeping, and your bus driver. You can use dollars in many places in Turkey, and it keeps things easy for quick purchases of small items. Note that if you give a shopkeeper payment in dollars, they will give you change in lira. If you would like to get shekels for your trip, we recommend withdrawing lira via ATM upon your arrival. There are plenty of ATMs at the airport. Tipping housekeeping staff and others in the local currency is an extra blessing you can give them, as they will not lose the value of the tip money when exchanging it!
