Hardangervidda: Norway's Largest Mountain Plateau

Hardangervidda is a vast mountain plateau in southern Norway, spanning approximately 8,000 square kilometers across the counties of Vestland, Viken, and Vestfold og Telemark. Averaging 1,100 to 1,400 meters above sea level, it is Europe's largest mountain plateau — a windswept, treeless expanse of rock, lakes, and tundra that feels more like the Arctic than western Europe.

Introduction

The plateau is famous for its wild reindeer herd, the largest in Europe, and for a Stone Age history of human reindeer hunting that stretches back over 8,000 years. As a national park since 1981, Hardangervidda protects an ecosystem that serves as a refugium for Arctic species at the southern edge of their range, making it a critical indicator of how climate change is affecting Europe's mountain environments.

Geography & Dimensions

• Area: ~8,000 km² (total plateau)
• National Park: 3,422 km²
• Average Elevation: 1,100-1,400 m
• Highest Point: Hardangerjøkulen glacier area, ~1,862 m

Hardangervidda sits between the deep fjords of western Norway and the forested valleys of the east, forming a broad, gently undulating plateau dissected by river valleys and dotted with over 800 lakes. The western edge drops steeply toward Hardangerfjord, one of Norway's longest fjords, while the eastern boundary transitions more gradually into the forested slopes of Telemark.

The plateau preserves the remnants of an ancient peneplain — an erosion surface formed when the land was near sea level — that was subsequently uplifted and modified by Ice Age glaciation. The Hardangerjøkulen glacier on the northwestern edge of the plateau is Norway's sixth-largest glacier and feeds meltwater into the Vøringsfossen waterfall, which plunges 182 meters into the Måbødalen valley below.

Climate & Arctic Ecology

• Temperature: Winter: -20 to -30°C; Summer: 10-15°C
• Annual Precipitation: 500-1,500 mm (west to east gradient)
• Snow Cover: October to June on much of the plateau
• Biome: Alpine tundra and low-alpine heath

Hardangervidda has a harsh, sub-arctic climate despite its relatively low latitude (60°N). Winter temperatures regularly drop below -20°C, with extremes approaching -40°C during cold snaps. Snow typically covers the plateau from October to June, with some snowfields persisting through summer in sheltered locations. The western plateau receives up to 1,500 mm of precipitation, while the eastern side is drier at 500-700 mm.

The plateau's vegetation is classified as alpine tundra, dominated by dwarf shrubs (Empetrum, Vaccinium), lichens, mosses, and grasses. Above roughly 1,300 meters, vegetation becomes increasingly sparse, giving way to bare rock and snow. The plateau supports a flora and fauna typical of the Arctic — including Arctic fox, snowy owl, and rock ptarmigan — at latitudes far south of their main range. This makes Hardangervidda a critical refugium for these species in a warming climate.

Wild Reindeer

• Herd Size: ~6,000-7,000 animals (target population)
• Historical Herd: Once over 15,000
• Migration: Seasonal movements between winter and summer ranges
• Hunting: Regulated annual hunt of ~2,000 animals

Hardangervidda is home to Europe's largest population of wild reindeer (Rangifer tarandus), distinct from the semi-domesticated reindeer of Sámi herders in northern Scandinavia. The herd moves seasonally across the plateau, spending winters in the more sheltered eastern areas and migrating west to summer calving grounds near the glaciers and snowfields that provide relief from insect harassment.

The reindeer population has fluctuated significantly over the past century, reaching peaks of over 15,000 animals that caused severe overgrazing, followed by crashes and management reductions. The current target population is approximately 6,000-7,000, maintained through a regulated annual hunt that also serves as an important cultural tradition. Climate change is disrupting reindeer migration patterns, as icing events — where rain freezes on the ground, locking food beneath a layer of ice — become more frequent during winter warm spells.

Human History & Stone Age Heritage

• Human Presence: 8,000+ years of reindeer hunting
• Archaeological Sites: Over 250 Stone Age sites recorded
• Key Finds: Hunting blinds, pitfall traps, arrowheads
• UNESCO Status: Part of the Rjukan-Notodden Industrial Heritage Site

Humans have hunted reindeer on Hardangervidda for at least 8,000 years, making it one of Europe's most important archaeological landscapes for understanding the Stone Age. Over 250 sites have been recorded on the plateau, including hunting blinds (low stone walls behind which hunters hid), pitfall traps, and arrow and spearpoint manufacturing sites. The distribution of these sites reveals ancient reindeer migration routes that are remarkably similar to those used by the herds today.

Melting snow patches and glaciers have recently revealed extraordinarily well-preserved artifacts, including wooden arrows with intact fletching, leather shoes, and textile fragments dating back thousands of years. These "ice patch archaeology" discoveries, driven by climate change, are providing unprecedented glimpses into the material culture of Hardangervidda's ancient hunters. A bow dating to around 3,900 years ago was recovered from a melting ice patch in near-perfect condition.

Hiking & Access

• DNT Cabins: Over 30 staffed and self-service cabins
• Major Routes: Oslo-Bergen railway crosses the plateau
• Best Season: July-September for hiking; March-April for ski touring
• Difficulty: Moderate, but weather can be severe

Hardangervidda is one of Norway's premier wilderness hiking destinations, with an extensive network of trails and mountain cabins operated by the Norwegian Trekking Association (DNT). Over 30 cabins, ranging from fully staffed lodges to simple self-service huts, allow hikers to cross the plateau over multiple days without carrying a tent. The classic crossing from Finse (on the Bergen railway) to Kinsarvik on Hardangerfjord takes 4-6 days.

The Oslo-Bergen railway, one of Europe's most scenic rail journeys, crosses the northern edge of the plateau at Finse station (1,222 m), providing easy access to the western plateau. Ski touring across Hardangervidda in March and April, staying in DNT cabins, is a quintessential Norwegian mountain experience. However, the plateau's weather demands respect — whiteout conditions, extreme wind, and rapid temperature drops can occur at any time, and several fatalities occur each decade among unprepared hikers and skiers.

Key Facts

• Hardangervidda covers ~8,000 km² at 1,100-1,400 m, making it Europe's largest mountain plateau.
• It supports Europe's largest wild reindeer population of approximately 6,000-7,000 animals.
• Over 250 Stone Age reindeer hunting sites have been recorded on the plateau.
• Melting ice patches are revealing remarkably preserved artifacts up to 6,000 years old.
• The plateau has a sub-arctic climate with winter temperatures reaching -30°C or below.

Fun Facts

• The Oslo-Bergen railway across Hardangervidda is the highest mainline railway in northern Europe.
• Finse station on the plateau was used as a filming location for the ice planet Hoth in The Empire Strikes Back.
• A 3,900-year-old bow recovered from a melting ice patch on Hardangervidda was still intact enough to bend.
• The plateau's reindeer migration routes have remained essentially unchanged for 8,000 years, as revealed by matching archaeological sites with modern GPS tracking data.

Final Thoughts

Hardangervidda is Europe's most accessible piece of true wilderness — an Arctic landscape within a day's travel of continental Europe's largest cities. Its combination of ancient geology, Ice Age ecology, 8,000 years of human history, and the spectacle of Europe's largest wild reindeer herd makes it irreplaceable. As climate change melts the plateau's ice patches and disrupts reindeer migrations, Hardangervidda is both a monument to deep time and a thermometer measuring the pace of environmental change.
