Strong winds are common, especially in coastal areas, and can make conditions feel much colder.Always carry a waterproof jacket, sturdy boots, and gloves, even in summer. In winter, icy roads and storms may disrupt travel plans, so keep an eye on weather forecasts using vedur.is and plan flexibility into your itinerary. 2. Iceland is Expensive Expect higher prices for everything, from meals at restaurants to basic groceries and fuel. Dining out can cost upwards of $30–$50 per person for a simple meal, so consider cooking your own food. Budget supermarkets like Bónus, Krónan, and Nettó are great for stocking up on supplies.Many travelers also save by bringing snacks or dry foods from home. Accommodation, especially in remote areas, can be limited and pricey, so plan ahead to avoid overspending. 3. Driving Can Be Challenging Driving in Iceland gives you freedom, but it’s not always easy. Gravel roads, sudden fog, and one-lane bridges require caution. F-Roads (highland mountain roads) require 4x4 vehicles and are open only in summer.Additionally, Icelandic sheep roam freely and might cross the road unexpectedly! Use road.is for live updates on road conditions, closures, and weather warnings.

Cards Are King But Cash Can Be Use Iceland is one of the most cashless countries in the world. Credit and debit cards are accepted everywhere, including small towns, food trucks, and parking meters. A PIN is often required for transactions, so make sure your card has one. If you do want cash, ATMs are available, but you likely won’t need it unless you prefer tipping in cash (though tipping isn’t expected in Iceland). 5. Respect Nature Iceland’s breathtaking landscapes are its biggest draw, but they’re also fragile. Stepping off marked paths damages moss and plants that can take decades to recover.Hot springs and volcanic areas may look inviting but can be dangerous, with scalding water or unstable ground. Always follow signs, listen to local advice, and avoid littering. Stay safe while respecting Iceland’s pristine environment. 6. Plan for Daylight Extremes Iceland’s location near the Arctic Circle means daylight varies dramatically throughout the year. From May to August, the Midnight Sun provides nearly 24 hours of daylight, ideal for late-night hikes or photography.In contrast, from November to January, daylight may last as little as 4 hours. This impacts your ability to explore, so plan key activities during daylight and pack a headlamp for winter visits. 7. Icelandic Tap Water is the Amazing Iceland’s water is some of the purest in the world, sourced from natural springs and glaciers. You can drink directly from the tap, even in remote areas. Hot water from taps may smell like sulfur due to geothermal activity, but it’s completely safe. Carry a reusable water bottle and refill it as you go to save money...
