Ilulissat Kangerlua: What Visiting the World’s Most Productive Glacier Actually Involves

The Sermeq Kujalleq glacier discharges approximately 20 billion tonnes of ice into the fjord annually. It is the fastest-moving glacier in the northern hemisphere, advancing and calving at a rate that researchers measure in metres per day rather than per year. The icebergs that result from this process are so enormous that they frequently ground on the shallow seafloor at the mouth of the fjord before eventually breaking free and drifting south into the North Atlantic shipping lanes. The one that sank the Titanic is generally believed to have originated here.

This is Ilulissat Kangerlua, or the Ilulissat Icefjord, inscribed on the UNESCO World Heritage List in 2004 for the combined scientific and visual value of this ice-calving system. It sits on the west coast of Greenland, about 250 km north of the Arctic Circle, and around 5,000 people live in the town of Ilulissat that overlooks it.

Getting There

Access has always been the main practical barrier. Until recently, reaching Ilulissat required flying through Copenhagen to Kangerlussuaq, then connecting to Ilulissat on Air Greenland, with the whole journey taking the better part of a day. The situation is improving materially: from October 2026, Air Greenland launches a direct service between Copenhagen and Ilulissat, coinciding with the opening of a new airport terminal in the town. Icelandair operates seasonal flights from Reykjavik to Ilulissat between June and September. From within Greenland, Air Greenland connects Ilulissat to Nuuk with 2 to 3 daily flights taking about 90 minutes.

There is no road connection to Ilulissat from anywhere. Everything arrives and departs by air or, in summer, by sea.

The Icefjord

The fjord itself is approximately 40 km long. You cannot sail into it because the density of icebergs and unpredictable calving makes navigation too dangerous, but you can see it comprehensibly from the walking trail that runs along the southern rim. The main trail from town passes the Sermermiut archaeological site and follows the fjord’s edge to a viewpoint above the ice-choked mouth where icebergs queue up before they can exit. The walk is about 6 km return and takes 2 to 3 hours on a clear day. It is accessible year-round, with snowshoes or crampons required in winter.

Boat tours go out into Disko Bay to approach the icebergs that have already exited the fjord and are floating freely. These trips give you a sense of scale that photographs rarely convey: icebergs the size of apartment buildings, with only the top 10 percent visible above the waterline. Summer evening departures, operating during the midnight sun period from late May to mid-July when the sun stays above the horizon, catch the low warm light that turns the ice amber and gold. These tours book out quickly in peak season; reserve in advance through operators in Ilulissat.

Sermermiut

The Sermermiut settlement ruins, on the cliff trail between town and the main icefjord viewpoint, are one of the best-integrated archaeological sites in the Arctic. Human cultures have used this spot for over 4,000 years: Saqqaq, Early Dorset, and Thule peoples all lived here, with the Early Dorset occupation carbon-dated to around 600 to 200 BCE. In 1737, Sermermiut was the largest settlement in Greenland. It was abandoned in 1850 when the remaining residents moved to what is now Ilulissat town.

The ruins are marked by low stone walls, tent rings, and depressions in the tundra. The permafrost layer that has preserved them for centuries is now thawing due to climate change, causing erosion that archaeologists are racing to document. Most visitors walk past them focused on the fjord view; stopping to look at them properly adds context that makes the landscape more than just a backdrop.

The Icefjord Centre

The Icefjord Centre museum, opened in 2021 and designed by Dorte Mandrup Arkitekter, sits on the fjord rim and covers the glaciology and cultural history of the area. The building’s form is deliberately low and angular to avoid competing with the landscape. Exhibits on glacier dynamics, Inuit history, and climate change are well-produced and worth two hours. It is the best introduction to what you are looking at if you arrive without background knowledge.

Activities

Hiking: The fjord trail is the most accessible. For longer routes, local guiding companies run multi-day walks into the backcountry around the Disko Bay area.

Dogsled: The traditional season runs from February to April when sea ice and snow cover are stable. This is the primary period for experiencing travel methods that Greenlandic hunters have used for centuries. Ilulissat has several operators who run day trips and multi-day expeditions.

Kayaking: Summer sea kayak tours between icebergs in Disko Bay are offered by outfitters in town. Experience in cold-water sea kayaking is required for independent hire; guided tours are available for beginners.

Northern Lights: The period from September to April, when darkness returns to the Arctic sky, offers northern lights viewing. February and March are generally considered the best months for combining lights with dogsled activities and manageable temperatures.

Whale Watching: Humpback and minke whales feed in Disko Bay during summer, following the same krill and fish as the local fishing fleet. Boat tours in July and August have a high sighting rate.

When to Visit

Ilulissat has two very distinct seasons. Summer (June to August) offers the midnight sun, maximum iceberg activity as winter-calved ice moves through the fjord, and the best weather for hiking and boating. Temperatures are typically 5 to 15 degrees Celsius. Winter (February to April) offers dogsled travel, northern lights, and the clarity of a truly dark Arctic sky, but temperatures drop to minus 20 Celsius or below, and some activities are unavailable.

The midnight sun period (late May to mid-July) is the most spectacular visually, particularly for the evening boat tours. Book accommodation months in advance if you are visiting in July.

Where to Stay

Hotel Arctic is the main 4-star property in Ilulissat, sitting directly above the fjord with icefjord-view rooms. It runs two restaurants, including Restaurant Ulo which serves Greenlandic cuisine with a focus on local seafood and game, and offers a shuttle from the airport 5 minutes away. Nightly rates start around $175 and rise significantly for fjord-view rooms in peak season.

Hotel Søma and the Best Western Plus Hotel Ilulissat are smaller alternatives with competitive pricing. Budget guesthouses and self-catering apartments are available in town for travellers trying to keep costs down, though accommodation in Ilulissat is expensive by any standard given the logistical difficulty of supplying the town.

Where to Eat

Restaurant Icefiord and Inuit Cafe in town are the main alternatives to hotel dining. Greenlandic cuisine in Ilulissat centres on what can be sourced locally: halibut, Arctic char, shrimp, musk ox, and reindeer. These are not dishes you will easily find elsewhere, which makes trying them worthwhile even at Greenland’s high price points. A main course at a sit-down restaurant typically costs 200 to 350 Danish Krone.

Greenland uses the Danish Krone (DKK), and card payment is accepted in hotels and most restaurants.

Practical Notes

Ilulissat sits at 69 degrees north, well inside the Arctic Circle. Even in summer, temperatures can drop sharply when wind comes off the ice. Layered waterproof clothing is required for any outdoor activity regardless of the season you visit.

The new direct Copenhagen to Ilulissat service from October 2026 will change the logistics considerably, cutting travel time and eliminating the Kangerlussuaq stopover. Check Air Greenland’s schedule before booking if your travel falls in late 2026 or beyond.

Photography of icebergs is almost impossible to overdo, but the most interesting light is during the low-sun hours of the midnight sun period, roughly 22:00 to 02:00 in local time (West Greenland Time, UTC-3 in summer). Setting your alarm for midnight is not unusual behaviour among photographers here.

Book boat tours as soon as accommodation is confirmed; July slots sell out weeks or months in advance.
