Located just north of the Arctic Circle, Sisimiut is the northernmost town in Greenland where the port remains free of ice in the winter. Yet it is also the southernmost town where there is enough snow and ice to drive a dogsled in winter and spring. In Sisimiut, travelling by sled has been the primary means of winter transportation for centuries. In fact, the area has been inhabited for approximately 4,500 years. Modern Sisimiut is the largest business center in the north of Greenland, and is one of the fastest growing Greenlandic cities. Commercial fishing is the lead economy in the town‘s thriving industrial base.
