The Westfjords or West Fjords is the name of the large peninsula in northwestern Iceland and an administrative district. It lies on the Denmark Strait, facing the east coast of Greenland. It is connected to the rest of Iceland by a 7 km wide isthmus between Gilsfjörður and Bitrufjörður. The Westfjords are very mountainous; the coastline is heavily indented by dozens of fjords surrounded by steep hills. These indentations make roads very circuitous and communications by land difficult.
