Iceland is one of the most expensive countries in the world to visit, although there are ways to keep costs down, such as by renting a camper van. Overall, visitors should be looking at a daily per-person budget of between USD 100 and USD 200. Most hotels, restaurants, and shops accept credit cards from major providers, and there are no minimum purchase requirements. Since cards are the preferred method of payment, you should be okay even if you avoid carrying cash completely, although having some for emergencies is always a good idea.
