All charges are made in the tour operators currency: For tours in Iceland it's Icelandic krona, ISK, but for tours in Canada/Greenland it's either USD or CAD. On Adventures.com you can view an estimate of prices in EUR and other currencies. This is only to help you understand the approximate price. Your credit card will always be charged in the operators currency. Keep in mind that your card issuer may charge you a foreign transaction fee.
