Experience - a couple of years ago in October, I rented a car in Akureyri and spent 2 days driving around the north-east of Iceland (to Dettifoss, Lake Mytvan, etc) so I am familiar with that part of the Ring Road.
I am returning to Iceland in May. My flight arrives at Keflavik at 6:30 am. I am considering driving the Ring Road the long way around to arrive in Akureyri the same night. Google tells me this is about 940 km and will take approx. 11-12 hours I realize I will not have much time to stop for sightseeing, however, I believe the views while driving will make up for it. Since this is mid-May there will be plenty of sunshine all day, so no worries about driving in the dark.
Any suggestions ? Advice ?
