Credit cards are widely accepted in Greece, especially in major cities and tourist areas. It is generally safe to rely on credit cards for most transactions, such as dining, shopping, and accommodation. However, it is advisable to carry some cash for smaller establishments or when visiting more remote areas where card acceptance may be limited. ATMs are readily available throughout Greece, allowing you to withdraw cash in the local currency, Euros. It is advisable to inform your bank of your travel plans to avoid any issues with card usage and to check if any fees or charges apply for international transactions.
