Dalvíkurbyggð is a small municipality on the western shore of Eyjafjörður, northern Iceland's largest fjord. The main town of Dalvík (population around 2,000) is a working fishing port that serves as the departure point for the ferry to Grímsey — Iceland's northernmost inhabited island, sitting right on the Arctic Circle.
The area is a good base for exploring the Tröllaskagi peninsula, one of Iceland's most scenic coastal stretches with dramatic mountain passes and remote fjords. Dalvík itself hosts the annual Fiskidagurinn mikli (Great Fish Day) festival in August, where the town's entire catch is grilled and served free. Whale watching tours operate from nearby Hauganes.
From Árskógssandur, a short drive south, a ferry crosses to Hrísey, a small island in the middle of the fjord known for its birdlife and tranquility. The Svarfaðardalur valley inland offers horseback riding and farmhouse accommodation.
