PARKING IN ICELAND

But unlike all other countries, if you are traveling along Route 1 Ring Road, parking at most tourist attractions, for example, the car parks close to waterfalls, glaciers, and volcanos are FREE. So the actual parking fee you must pay during your stay in Iceland comes down to where and when you park your car.
In urban areas, you may need to pay for parking. Parking meters or pay-and-display machines typically accept coins or credit cards. May sure to display your parking ticket on your dashboard. some cities require a parking payment only within a certain time period during the day. For all designated parking locations, you will see a "P" sign with a blue background. This sign indicates that you can park your car here, and you will need to pay for parking in these areas most of the time.
You will also find this paid Parking area in some famous tourist attractions, for example, the Thingvellir National Park and Seljalandsfoss waterfall.
