I have just spent 10 lovely nights in Sisimiut! In my opinion, Sisimiut is quite an easy town to be a tourist in. It is easy to get to/from, and it is easy to find information once you arrive. You can get to/from Sisimiut by Air Greenland flights, by the 160 km Arctic Circle Trail, and by the Arctic Umiaq Line ferry, Sarfaq Ittuk. It seems that most tourists take advantage of these opportunities to be quite mobile. In Sisimiut, there are choices for accommodations, excursions, shopping, and local hangouts, but not so many that you feel like you are missing something perhaps. Information about excursions is readily available at all of the accommodations, and arrangements can be made on the spot.
Sisimiut is commonly the end point for trekkers who do the Arctic Circle Trail, so tourists and locals both help create the relaxed and quiet atmosphere. For those who want to relax in town, there are a number of nice cafés and shops to discover as well as the culture house, called Taseralik, the Arctic Technical Centre, and the Museum. For those who are looking for more activity, there are daytime sailing tours, helicopter flights, and two mountains close by to hike (551 – 775 meters / 1,808 – 2,543 feet). Finally, for those with a special interest in fishing, Sirius Greenland has two field camps where you can fish for all the Arctic Char your little heart desires! They can even help you with SCUBA diving! And of course, for those who want to get away from it all and enjoy the sounds of silence, the backcountry of Sisimiut is your oyster!
