Travelers should rent a car for the duration of their trip in Iceland to allow for maximum flexibility and the opportunity to explore more remote areas. Most rental companies require a valid driver's license, a credit card for payment, and drivers must be at least 21 years old. Gas averages about $5 per gallon in Iceland. Travel times between destinations can vary greatly due to road conditions, so it is important to plan for extra time to ensure ample time for exploration.
If you have more time, consider spending another day in the Vatnajökull National Park area to explore even more of the stunning glaciers and waterfalls. If you have less time, consider shortening the stay in the Eastfjords or Snaefellsnes Peninsula. Be sure to always check weather conditions before traveling and plan for extra time as needed due to weather or road conditions. Also, don't forget to pack warm and waterproof clothing, as the weather in Iceland can change quickly!
