Breidafjordur is a vast fjord that one goes across by ferry. This sea journey spares you a good distance of bends and winding roads to access the Western Fjords.
You must count 2 hours 30 for the crossing which allows you to contemplate at will the massive mountains which all seem really small from here, but which turn out to be impassable walls once you are on land. If you have a car, you must book in advance, especially in summer when the crossing is popular.
I made this crossing from Brjanslaekur and the drive to get there took so long that I feared I would not arrive in time to catch the boat. Moreover, my level of petrol was low and as there are not many people in this part of the island, I was a little scared of running out of petrol in the middle of nowhere before getting back to civilisation!
Breidafjordur counts numerous islands, some being more like big rocks, but one of them, however, deserves a stop: Flatey. Lovers of birds and peacefulness will particularly appreciate this stop while on their Iceland trip.
