The official currency of Egypt is the Egyptian Pound (EGP), and it is best to bring this currency with you when traveling to Cairo. It is recommended to exchange currency at a bank or reputable money exchange office upon arrival, as they usually offer better exchange rates than airports and hotels. Credit cards are widely accepted in tourist areas, but cash is still preferred in local markets and smaller stores. It is always a good idea to carry a mix of cash and credit cards for your trip.
