Großer Arber
Großer Arber, known in Czech as Velký Javor, is the highest mountain in the Bavarian Forest and the wider Bohemian Forest mountain system. Rising to approximately 1,455.5 meters (4,775 feet) in southeastern Germany, it towers above a landscape of dense forests, glacial lakes, rocky summit formations, and deep valleys near the Czech border.
Often called the “King of the Bavarian Forest,” Großer Arber is especially notable for its topographic prominence. Despite being far lower than the nearby Alps, it rises more than 1,000 meters above its key saddle and is one of Germany’s most prominent non-Alpine mountains.
🏔️ Overview
Großer Arber stands in Bavaria, Germany, near the communities of Bayerisch Eisenstein and Bodenmais. The summit lies within the district of Regen, while parts of the mountain extend toward the district of Cham.
The mountain is the highest point of both the Bavarian Forest and the broader Bohemian Forest, a mountain system that extends across the German-Czech border.
Unlike the sharp limestone summits of the Alps farther south, Großer Arber belongs to the ancient Bohemian Massif. Its rounded, forest-covered slopes and resistant metamorphic rocks reflect hundreds of millions of years of geological history.
At the summit, rocky outcrops rise above an unusually open high-elevation landscape. Großer Arber actually has several distinct summit points, including the main summit, Bodenmaiser Riegel, Kleiner Seeriegel, and Großer Seeriegel.
Although the summit is only about 1,455 meters high, its exposed position creates a surprisingly harsh mountain environment.

📍 Location
Großer Arber rises in Lower Bavaria close to Germany’s border with the Czech Republic. Its summit lies within the municipality of Bayerisch Eisenstein, while the southwestern slopes descend toward Bodenmais.
The mountain belongs to the rear, or higher, section of the Bavarian Forest. Across the border in Czechia, the same broader mountain landscape continues into the Šumava, or Bohemian Forest.
This border region forms one of Central Europe’s great forest landscapes. Mountain ridges, peatlands, glacial lakes, streams, and extensive woodland stretch across both countries.
Großer Arber is particularly important geographically because it is the highest point in this entire mountain system. Nearby Jezerní hora in Czechia reaches 1,344 meters, while Großer Osser rises to 1,293 meters along the German-Czech border.
📏 Elevation & Prominence
The commonly published elevation of Großer Arber is approximately 1,455.5 meters (4,775 feet), frequently rounded to 1,456 meters.
Peakbagger’s lidar-based data gives an elevation of 1,455.1 meters (4,774 feet) using the German DHHN2016 vertical datum. The small difference simply reflects survey methods, vertical datums, and rounding.
What makes Großer Arber particularly impressive is its prominence.
Peakbagger calculates a topographic prominence of 1,026 meters (3,366 feet) and an isolation of 146.51 kilometers (91.04 miles).
That means the mountain rises more than a vertical kilometer above the highest saddle connecting it to higher terrain.
Its nearest higher neighbor in the Peakbagger database is Traunstein, a 1,691-meter mountain in the Austrian Salzkammergut.
Großer Arber is therefore much more geographically independent than its relatively modest elevation might suggest.
🪨 Geology
Großer Arber is part of the ancient Bohemian Massif, one of Central Europe’s oldest major geological structures.
Unlike the much younger Alps, which formed largely through the collision of the African and Eurasian tectonic plates, the rocks of the Bavarian and Bohemian Forests record geological events stretching back hundreds of millions of years.
The summit region of Großer Arber consists primarily of paragneiss.
Paragneiss is a metamorphic rock formed when older sedimentary rocks are transformed under intense heat and pressure. Repeated episodes of deformation, uplift, weathering, and erosion gradually exposed these resistant rocks at the surface.
Long periods of erosion softened what were once much higher mountains, producing the broad ridges and rounded profiles now characteristic of the Bavarian Forest.
Ice Age glaciers later reshaped portions of the Arber massif.
Small mountain glaciers carved cirques into its slopes and helped form the basins now occupied by Großer Arbersee and Kleiner Arbersee.
These lakes are among the clearest reminders that glaciers once occupied this comparatively low mountain landscape.
🌿 Flora & Fauna
The ecology of Großer Arber is unusually diverse because of its elevation, severe summit climate, extensive forests, exposed rock, and glacial landforms.
Much of the mountain is covered by spruce, fir, beech, and mixed mountain forest.
Near the summit, however, the landscape changes dramatically.
Interestingly, Großer Arber does not reach the normal climatic tree line. Nevertheless, parts of its exposed summit region are naturally treeless. Low temperatures, strong winds, heavy snow, ice, and a short growing season have produced vegetation resembling a subalpine environment.
The summit supports rocky grasslands, dwarf shrubs, mountain pine, and hardy plants adapted to severe weather.
Birds associated with the high mountain environment include:
- Ring ouzel
- Water pipit
- Meadow pipit
- Alpine accentor
- Northern wheatear
The surrounding forests provide habitat for red deer, roe deer, foxes, wild boar, woodpeckers, owls, and many smaller woodland species.
The wider Bavarian-Bohemian Forest landscape is also important habitat for the Eurasian lynx.
Several protected areas surround the mountain, including conservation zones associated with the two Arber lakes, forest habitats, and important bird areas.
🧊 The Arber Lakes
Two remarkable glacial lakes lie beneath the Arber massif.
Großer Arbersee lies southeast of the summit. It occupies a basin formed by glacial erosion and is surrounded by steep forested slopes and protected habitats.
Kleiner Arbersee lies northwest of the main summit, below Kleiner Arber.
Both lakes are relics of the last Ice Age. After the glaciers disappeared roughly 10,000 years ago, water accumulated in the depressions they had excavated.
Peat-forming vegetation later developed around portions of the shorelines.
The lakes are now among the Bavarian Forest’s most distinctive natural landmarks and provide an excellent way to understand how glaciation shaped the Arber landscape.
🥾 Hiking & Climbing Routes
Großer Arber is primarily a hiking mountain rather than a technical climbing peak. Numerous marked trails reach the summit from surrounding valleys and high trailheads.
One of the classic approaches begins near Bodenmais and climbs through the Rißloch area.
The trail passes the Rißloch waterfalls, where streams cascade through a steep forested gorge before the route continues toward higher slopes.
Another approach uses the high recreation area around Bretterschachten, allowing hikers to reach the Arber massif through forests and upland terrain.
Longer hiking routes can connect Großer Arber with surrounding peaks, including Kleiner Arber and other summits of the Bavarian Forest.
The mountain is also incorporated into sections of the extensive Goldsteig hiking network.
Visitors who do not want to make the entire ascent on foot can use the mountain’s gondola system when it is operating. From the upper station, walking paths provide access to the summit plateau and viewpoints.
🏔️ Field Guide Tip: Do not underestimate Großer Arber because of its relatively low elevation. The exposed summit can experience fog, strong winds, rapid temperature changes, snow, and ice when conditions in the valleys are comparatively mild. Check current mountain weather and trail conditions before starting your hike.
❄️ Großer Arber in Winter
Großer Arber is one of the best-known winter sports mountains in the Bavarian Forest.
Snowfall and relatively cold conditions have made its slopes a long-established destination for skiing and snowboarding. Ski lifts and groomed slopes occupy portions of the mountain, while the surrounding region also offers cross-country skiing and winter hiking.
Snow can transform the summit vegetation into strange ice-covered forms. Wind-driven snow and rime accumulate on mountain spruce and pine, sometimes creating dramatically distorted shapes.
Winter conditions can nevertheless be severe.
Fog, ice, deep snow, wind, and limited visibility can quickly make hiking considerably more difficult. Anyone venturing away from developed ski areas should carry appropriate winter equipment and understand current conditions.
🌤️ Best Time to Visit
Großer Arber can be visited throughout the year, but the best season depends on the activity.
Late spring through early autumn generally provides the most straightforward hiking conditions. Snow retreats from the upper mountain, trails become easier to follow, and longer daylight allows hikers to explore surrounding lakes and ridges.
Summer is popular for hiking, family outings, and summit sightseeing. Temperatures are normally more comfortable, although thunderstorms and sudden weather changes remain possible.
September and early October can be particularly attractive. Cooler temperatures, fewer visitors, and autumn colors create excellent conditions for photography and hiking.
Winter is ideal for skiing, snowshoeing, and experiencing the snowy Bavarian Forest, but mountain travel requires greater preparation.
Conditions vary substantially from year to year, so seasonal dates should never replace a current weather and trail report.
🛰️ The Summit and Radar Domes
One of Großer Arber’s most recognizable features is the pair of large white radomes visible near the summit.
A military radar facility was constructed here during the Cold War because the mountain offered an excellent position for monitoring airspace near what was then communist Czechoslovakia.
The installation entered service in the early 1980s and later received updated radar equipment.
Although the radar structures give the summit an unusual modern appearance, several older landmarks can also be found around the upper mountain.
A summit cross has stood on the main top since 1913, while a small chapel dedicated to Saint Bartholomew stands just below the summit.
The combination of rocky outcrops, mountain paths, summit structures, radar domes, and sweeping views makes the upper Arber unlike almost any other summit in Germany.
🧭 Nearby Mountains & Attractions
Großer Osser lies northwest of Großer Arber along the German-Czech border. Reaching approximately 1,293 meters, its distinctive rocky summit offers another excellent hiking destination within the Bavarian-Bohemian Forest.
Jezerní hora lies across the border in Czechia. At 1,344 meters, it is one of the higher summits of the Šumava region and illustrates how the mountain landscape continues seamlessly across the international boundary.
Großer Arber also makes a natural addition to a broader exploration of the peaks described in our guide to the Mountains in Germany.
