“Iceland comfortably in 15 days” - a trip in 2023 in a rental car with all-wheel drive (4WD) - Part1

We travel Iceland in 15 days in a rental car with four-wheel drive (4WD). Part 2.
A wonderful tourism trip.
The original Iceland is our destination. We want to make our vacation as active as possible.
So that we can move a little off the paved road, we chose a rental car with four-wheel drive.
