There is no Antarctic currency. However, if you visit Port Lockroy in the Antarctic Peninsula, US dollars, Pound Sterling and Euro are accepted, as are Visa and MasterCard. Your transaction will be charged in US dollars. Onboard purchases made during your voyage (shop, laundry, communications charges, drinks, etc.), will require your signature. This will be charged automatically to your cabin and at the end of your voyage you will receive an invoice. Most ships will accept all Mastercard and Visa major credit cards, US dollars or Euro cash. Please contact Antarctic Travel Specialists for currency accepted on the cruise and ship that you have booked on.
