Ilulissat means icebergs in Greenlandic, and the name is a plain description. The town sits at the mouth of the Ilulissat Icefjord, where the glacier Sermeq Kujalleq pushes out an enormous amount of ice every year, and the biggest bergs run aground on a shallow bank at the fjord mouth until they melt enough to float away. The fjord has been a UNESCO World Heritage Site since 2004. People have lived here for about 4,000 years, the Danish trading post was founded in 1741, and today around 5,000 people live in the town. It is the third largest town in Greenland, which is a self-governing part of the Kingdom of Denmark, with its own parliament and government, and Greenlandic as its official language.
This is not a city break. There are no roads out of town, no museum row and no nightlife to speak of. There are a few museums, a few good hotel restaurants, a lot of sled dogs and one of the great natural sights in the Arctic, a short walk from a visitor center. Five days is a good length because weather and ice decide what you can do, and you need slack. Flights are infrequent, boats don't leave in fog, and the northern lights or the whales don't come on schedule. Be honest with yourself about prices too: Greenland is expensive, flights alone cost several hundred euros, and almost every tour is 100 EUR or more.
The plan starts on a Wednesday, because that is the day of the weekly direct flight from Copenhagen and because the Icefjord Centre is open Wednesday to Sunday for most of the year (in 2026 it was daily from mid-June to mid-September and closed in December and January). Day one is the town, day two the Icefjord Centre and the boardwalk to Sermermiut, day three the yellow trail, whales and a kaffemik, day four the Eqi glacier, and day five the village of Oqaatsut and a boat among the icebergs. The plan is written for summer, June to September, when every boat runs. From November to April the same days still work: dogsleds or snowmobiles replace the whale boat on day three (January to April), the Eqi day becomes an Igloo Lodge trip (February to April), and in the polar night (26 November to 13 January, Icefjord Centre closed in December and January) you trade trails for the town and northern lights evenings. Our page on Denmark covers the wider kingdom. Read the season section in the essentials first, because the choice of month changes the whole trip.
