While traveling along northern coast, you can find three more residencies on the mainland and one on the island.
One more residency can be found on the second biggest island in Iceland – Hrísey. It is located in the old school and run by artist group Norðanbál. Old School House Residency in Hrísey can be considered as on of the most remote residency in Iceland because you need to take a ferry which runs only 7 times a day in winter time. I have not visited it personally but you can find out more about it in the website. It seems quite popular because in 2012 August it is already fully booked till Summer 2013.
