It can be stressful to make a plan when time is limited. That's why I created this guide to make sure you can get the most out of your short stay. It is designed for anything from 12 to 48 hours but the amount of things you'll be able to do depends on how much time you have and the timing of your flights. Feel free to mix and match the locations depending on your time of arrival.
NOTE: Due to the recent and current seismic activity in and around Grindavík and the Blue Lagoon, I didn't include them in the guide. But here you can check whether the roads around Grindavík are open.
