The first kilometers and the first fjords are really rewarding, including a common seal colony, but after the coffee shop at Litlibaer (very good!) the landscape gets more and more unintersting. We planned to stay a night haf way to Holmavik, but kept on driving as the area north of Holmavik lured as more than what we saw on the way to Holmavik. I must admit it was rainy and dark, it may be diffferent in nice weather, but I doubt it.
Rewarding is the seal colony, at least if you have binos, for photographers it is just ok as the distance to the animals is even for 800mm (full format mm's) a bit far. But make sure to pass the colony during low tide! Talking about wildlife I have to mention the Arctic Fox center close to Isafjördur as well. Arctic foxes are still common in the West Fjords, but elusive in the wild outside Hornstrandir nature reserve. In the center you learn a lot about the foxes and can view two foxes in an enclosure close to the building.
