Drive from Heydalur to Sauðárkrókur via Hvítserkur.
Distance: 352 km
Time to drive: 5:36 h

This drive and the stay in Sauðárkrókur is planned in as an interim stop on the way to Myvatn. Driving directly there would be a long trip.

Not sure whether it would make sense to go up the 745 to Skagaströnd and then follow the road around the peninsula Skagi.

 

Hvítserkur (Basaltfelsen)

 

Öxnadalur

The Oxnadalur is a valley in the north-east of Iceland. Optional to go there after check-in at the hotel in Sauðárkrókur.
