Hardangerjøkulen
🏔️ Overview
Hardangerjøkulen is a broad plateau glacier in southern Norway, occupying the northern edge of the Hardangervidda highlands in Vestland county. Shared between the municipalities of Ulvik and Eidfjord, it is one of the largest surviving ice masses in mainland Norway and an important landmark of the Scandinavian mountain landscape.
The Norwegian Water Resources and Energy Directorate (NVE) currently lists Hardangerjøkulen at approximately 64 square kilometers (24.7 square miles), making it the sixth-largest glacier in mainland Norway. Older references often give an area of about 73 square kilometers; the difference reflects both glacier shrinkage and newer glacier mapping.
Unlike a valley glacier confined to a single trough, Hardangerjøkulen forms an elevated ice cap from which several outlet glaciers descend toward the surrounding valleys. Its combination of accessible blue ice, dramatic outlet glaciers, long scientific record, and proximity to Finse makes it one of Norway’s best-known glaciers.

📍 Location
Hardangerjøkulen lies in Vestland county in southern Norway, on the northern side of Hardangervidda. The ice cap straddles the municipalities of Ulvik and Eidfjord, with the Bergen Railway running north of the glacier and the Simadalen valley lying to the south.
This location places the glacier within the broader landscape of the Scandinavian Mountains, although Hardangervidda itself is characterized more by extensive high plateaus than by continuous sharp alpine ridges.
Finse, on the Bergen Railway, provides the best-known gateway to the northern side of the ice cap. The combination of railway access and high-mountain terrain has made the Finse area an important base for hiking, skiing, glacier travel, research, and outdoor education.
🧊 Glacier Form & Major Outlet Glaciers
Hardangerjøkulen is classified as a plateau glacier, meaning that much of its ice occupies a broad high-level surface rather than being confined entirely within valleys. Gravity carries ice outward from the central plateau into several distinct outlet glaciers.
Among the most important outlets are:
Rembesdalskåka descends toward the southwest and is one of the largest outlets of the ice cap. It has also been especially important for scientific monitoring.
Blåisen flows toward the northeast and is known for its heavily crevassed ice front.
Midtdalsbreen descends on the northern side of the glacier near Finse and is one of the more accessible parts of the Hardangerjøkulen system.
The outlets respond differently to local terrain, elevation, snow accumulation, and melting. As a result, individual glacier fronts may advance or retreat at somewhat different rates even though they belong to the same ice cap.
📏 Size, Elevation & Ice Thickness
Hardangerjøkulen illustrates why glacier statistics need dates attached to them. An area of about 73 km² appears in many older publications and visitor guides, while NVE’s inventory based on Sentinel-2 satellite data from 2018–2019 gives 64 km². For a current Mountain Field Guide profile, 64 km² is therefore the better figure to use.
The highest fixed point associated with the glacier is now mapped at approximately 1,861 meters (6,106 feet) above sea level. Store norske leksikon notes that the top of the glacier reached about 1,876 meters in 1925, illustrating how loss of ice thickness can alter the elevation of an ice-covered landscape.
The greatest measured ice thickness is approximately 380 meters (1,247 feet). That enormous depth demonstrates that Hardangerjøkulen remains a substantial body of ice despite its long-term decline.
🪨 Glacial Landscape & History
The landscape around Hardangerjøkulen preserves extensive evidence of past glacier positions. Moraines, trimlines, glacial sediments, and erosion boundaries allow researchers to reconstruct where the ice once extended.
Research published in The Holocene reconstructed Hardangerjøkulen at approximately 110 km² around its Little Ice Age maximum, near AD 1750. By 2010, the ice cap had lost about 41 km², or 37 percent, of that reconstructed area. Researchers also calculated an average cumulative retreat of the outlet-glacier fronts of approximately 1.3 kilometers by 2013.
The retreat has not occurred at a perfectly steady rate. Individual outlets have experienced pauses and temporary advances, but the long-term change since the Little Ice Age has been a substantial reduction in the overall size of the ice cap.
These exposed glacial landforms effectively form a natural record of Hardangerjøkulen’s changing boundaries.
🌿 Flora & Fauna
The glacier itself provides little habitat for conventional terrestrial vegetation, but the ice-free terrain surrounding it belongs to a harsh alpine environment adapted to cold temperatures, short growing seasons, strong winds, and persistent snow.
Vegetation becomes sparse close to the glacier margins, where recently exposed surfaces may initially consist largely of bare rock, gravel, and glacial sediment. Farther from the ice, mosses, lichens, grasses, sedges, dwarf shrubs, and other hardy mountain plants gradually colonize more stable ground.
The surrounding Hardangervidda landscape is particularly important for wild reindeer. Ptarmigan and other mountain birds also occur in the wider region.
Because vegetation develops slowly in this environment, hikers should avoid trampling fragile alpine plants or creating unnecessary new paths across tundra.
🥾 Hiking & Glacier Travel
Finse is the best-known starting area for experiencing Hardangerjøkulen. Summer routes lead from the settlement toward the northern glacier outlets, while guided excursions provide opportunities to travel onto the ice itself.
Glacier hiking should be treated very differently from ordinary hiking. Crevasses can be hidden beneath snow, meltwater can alter routes, and ice surfaces can become extremely slippery. Proper glacier travel may require crampons, harnesses, ropes, helmets, ice axes, and the knowledge to use them safely.
Organized glacier trips from Finse generally use trained guides and appropriate glacier equipment. Weather can deteriorate quickly even in midsummer, and temperatures on or near the ice may be much colder than conditions at lower elevations.
🏔️ Field Guide Tip: If your goal is simply to see Hardangerjøkulen, you do not need to walk onto the glacier. Approaching a viewpoint near one of its outlets can provide an excellent experience without exposing yourself to the hazards of unroped glacier travel. Only enter glacier terrain with appropriate skills, equipment, and preferably a qualified guide.
🌤️ Best Time to Visit
For hiking and glacier sightseeing, the main season is generally July through early September, when high-country access is usually easiest and guided glacier activities operate around Finse. Even during this period, conditions can include strong wind, heavy rain, fog, freezing temperatures, or fresh snow.
Winter transforms the region into a major ski-touring landscape, but travel becomes substantially more demanding. Navigation in whiteout conditions, avalanche awareness, cold-weather equipment, and experience with remote winter terrain are essential.
There is no reliably “easy” season on Hardangerjøkulen. This is exposed Norwegian high country where weather can change quickly.
🌍 Glacier Retreat & Climate Change
Hardangerjøkulen has undergone major long-term shrinkage.
The reconstructed Little Ice Age ice cap covered roughly 110 km² around 1750. By 2010 it had lost approximately 37 percent of that area, and NVE’s more recent inventory puts the glacier at about 64 km².
The glacier has therefore become an important location for studying how plateau ice caps respond to changes in snowfall, summer melting, elevation, and regional climate.
NVE also maintains a long observational record associated with Hardangerjøkulen. Measurements on Rembesdalskåka began in the 20th century, making the outlet valuable for tracking glacier mass balance and changes in ice-front position over many decades.
Hardangerjøkulen is especially useful scientifically because its broad plateau and multiple outlet glaciers allow researchers to compare how different sections of a single ice cap respond to changing conditions.
🧭 Nearby Mountains & Attractions
Hårteigen
Hårteigen is one of the most recognizable mountains on Hardangervidda. Its distinctive steep-sided, flat-topped profile rises to about 1,690 meters southwest of Hardangerjøkulen and forms one of the plateau’s classic landmarks.
Sandfloegga
Sandfloegga rises to approximately 1,721 meters in the Hardangervidda region. Its position within the same broad southern Norwegian highlands makes it another useful reference point for understanding the terrain surrounding Hardangerjøkulen.
The glacier also lies close to Finse and the Bergen Railway, giving visitors an unusual opportunity to reach a remote high-mountain environment without a road approach.
