So there’s no “correct” way to do a road trip in Iceland. Do it at your own pace, and stop whenever you choose. But to give you an idea, the beginner’s 7-day road trip to Iceland would look like that:
Day 1: Driving from Reykjavik to the Golden Circle. It consists of the three most famous sites in Iceland: Þingvellir National Park, the geothermal area in Geysir and Gullfoss waterfall.
Day 2: The South Coast. This is one of my favourite areas of the country and filled with breath-taking wonders. There you have countless waterfalls, glaciers and black beaches.
Day 3 & 4: Skaftafell National Park. I recommend spending two days in the area, checking out some glacier tongues, hiking up to Svartifoss and then to Sjónarnípa.
Day 5: Höfn. After driving through the desolate South Coast, arriving in Höfn truly feels like entering a metropolis. Höfn is quite an important centre for tourists who travel around Iceland’s ring road.
Day 6 & 7: Return to Reykjavik with a few stops on the South Coast you’ve missed before (I recommend a short hike and a soak in the Reykjadalur hot river just a few hours away from the capital). In order to finish the whole Icelandic ring road, one needs 9–10 days.
