Hochgall
Hochgall, known in Italian as Monte Collalto, is the highest mountain of the Rieserferner Group in the Eastern Alps. Rising to 3,436 meters (11,273 feet) in South Tyrol, Italy, the mountain towers above the Antholz Valley near the Austrian border and forms one of the most distinctive summits in this heavily glaciated corner of the Hohe Tauern.
With more than 1,100 meters of topographic prominence, Hochgall is not merely the highest point of its immediate range—it is a major independent Alpine summit. Its steep ridges, tonalite rock, shrinking glaciers, and long mountaineering history make it particularly notable among the three-thousand-meter peaks of the Eastern Alps.
🏔️ Overview
Hochgall stands in the Rieserferner Group, a mountain group traditionally considered part of the Hohe Tauern. Although the main Alpine watershed and the Austrian border pass very close to the mountain, the summit itself lies on the Italian side in South Tyrol.
The mountain dominates views from the upper Antholz Valley and Lake Antholz. Its northern and western surroundings are characterized by rugged ridges, high cirques, and remnants of glaciers that were once considerably larger.
Hochgall also lies within Rieserferner-Ahrn Nature Park, one of South Tyrol’s major protected high-mountain landscapes. The park contains an exceptional concentration of glaciers and high summits and connects with protected areas across the Austrian border.

📍 Location
Hochgall rises in northeastern South Tyrol, close to the border between Italy and Austria. It is situated between the valleys of Antholz/Anterselva to the south and Rein in Taufers/Riva di Tures to the northwest.
The Austrian border passes only a short distance northeast of the summit. This geographic position places Hochgall within a dramatic cross-border mountain landscape where the Italian Rieserferner-Ahrn Nature Park meets Austria’s Hohe Tauern protected area.
Lake Antholz, or Antholzer See/Lago di Anterselva, lies south of the mountain and provides one of the best-known viewpoints toward Hochgall. From the valley, the summit appears particularly imposing because of its large prominence above the surrounding terrain.
📏 Elevation & Prominence
At 3,436 meters (11,273 feet), Hochgall is the highest summit in the Rieserferner Group.
Its approximately 1,148 meters (3,766 feet) of topographic prominence makes it an especially significant mountain within the Eastern Alps. The associated key saddle is the Klammljoch, while the higher Rötspitze forms the relevant higher summit beyond Hochgall’s isolation radius.
Hochgall’s isolation of approximately 13.7 kilometers (8.5 miles) means that a climber would have to travel that distance before encountering terrain rising above the summit’s elevation. That combination of elevation, prominence, and isolation explains the mountain’s commanding appearance from surrounding valleys.
🪨 Geology
Hochgall is especially interesting geologically because it forms part of the Rieserferner Pluton, one of the major Periadriatic intrusive bodies of the Eastern Alps.
Geological studies identify Hochgall itself as being composed primarily of fine-grained tonalite, an intrusive igneous rock related to granite but typically containing more plagioclase and dark minerals. The Rieserferner intrusion developed during Oligocene magmatic activity associated with the complex tectonic evolution of the Alps.
The larger pluton extends for roughly 40 kilometers and includes several tonalitic and granodioritic intrusive phases. Its emplacement was closely connected with regional fault structures, particularly the Defereggen-Antholz-Vals fault system.
This hard, erosion-resistant rock contributes to the steep ridges and rugged summit architecture seen across the Rieserferner Group.
Glaciers subsequently played an enormous role in sculpting the modern landscape. Cirques, moraines, glacially polished rock, erratic blocks, and small alpine lakes remain widespread throughout the region.
🌿 Flora & Fauna
Although Hochgall’s summit environment consists primarily of exposed rock, snow, and ice, the surrounding Rieserferner-Ahrn Nature Park supports a surprisingly diverse series of habitats.
Lower elevations contain spruce-dominated forests mixed with larch and Swiss stone pine. The timberline generally lies between roughly 1,900 and 2,200 meters, above which alpine grasslands and increasingly sparse vegetation dominate.
Alpine meadows support plants such as arnica, anemones, golden cinquefoil, and various sedges. At still higher elevations, specialized species including saxifrages and cushion plants can survive among scree and rocky ledges approaching 3,000 meters.
Wildlife found within the broader protected area includes:
- Chamois
- Marmots
- Red deer
- Roe deer
- Golden eagles
- Ravens
- Alpine accentors
- Snow mice
- Foxes
- Eurasian pygmy owls
Golden eagles regularly nest within the park, while chamois are capable of occupying the rocky terrain at very high elevations.
🥾 Hiking & Climbing Routes
Hochgall is a mountaineering objective, not an ordinary hiking summit. Reaching the top requires substantial alpine experience, exposure tolerance, route-finding ability, and climbing skills.
One traditional Italian approach reaches the mountain from the Rein in Taufers side and uses the Kasseler Hütte/Rifugio Roma as a base. From there, climbers historically followed terrain toward the Graues Nöckl and the northwest ridge. Sections of climbing reach approximately UIAA Grade II, with exposed terrain requiring confidence and good conditions.
New Summer Route from Lake Antholz
An important change occurred in 2025, when a summer route from the Antholz Valley was improved in cooperation with local mountain guides. The route was developed because the traditional spring ice-gully ascent becomes increasingly unsuitable after snowmelt.
The route begins near Lake Antholz at approximately 1,642 meters and initially follows trail No. 39 toward the Riepenscharte. Above the pass, the route enters rocky terrain marked partly by cairns.
Climbers encounter sections graded approximately UIAA II–III, with bolts and iron pegs assisting at selected locations. The upper climbing section reaches Grade III before arriving at the summit.
The Antholz tourism authority classifies the climb as difficult and recommends it only for experienced alpinists. Depending on conditions, equipment can include a helmet, harness, rope, crampons, and ice axe.
🏔️ Field Guide Tip: Hochgall should be treated as a serious high-alpine climb rather than a trail hike. Conditions on snowfields, gullies, and ridges can change dramatically during the season. Climbers unfamiliar with the mountain should strongly consider using a certified local mountain guide.
🌤️ Best Time to Visit
For hikers exploring the valleys and lower trails around Hochgall, summer through early autumn generally provides the most accessible conditions.
Summit climbing is considerably more complicated. The ideal route can change according to snow cover, glacier conditions, temperature, and seasonal rockfall.
Historically, snow and ice routes were often attempted earlier in the season while gullies remained filled with consolidated snow. By summer, melting can expose loose rock and make some traditional lines unsafe. The newer Antholz summer route was developed specifically to provide an alternative once the spring snow route becomes unsuitable.
Always obtain current local information before attempting the summit.
🧭 Nearby Mountains & Attractions
Hochgall sits among an impressive collection of high Alpine peaks and glacial landscapes.
Rötspitze
The Rötspitze rises northwest of Hochgall and reaches approximately 3,495 meters. It is Hochgall’s nearest higher neighbor and another major summit of the surrounding Hohe Tauern.
Wildgall
Wildgall rises immediately south of Hochgall, separated from it by the Schwarze Scharte. Its sharp summit profile adds to the dramatic mountain skyline seen from the Antholz Valley.
Schneebiger Nock
Schneebiger Nock is another major summit of the Rieserferner Group. Glaciers lying between it and Hochgall helped give the mountain group its name.
Lake Antholz
Lake Antholz is one of South Tyrol’s largest natural lakes and occupies a beautiful high valley beneath the surrounding mountains. It offers much easier walking opportunities for visitors who want to experience the Hochgall landscape without attempting technical mountaineering.
Rieserferner-Ahrn Nature Park
The surrounding nature park encompasses more than 31,000 hectares of forests, alpine meadows, rocky summits, lakes, waterfalls, and glaciated terrain. It is also part of a larger cross-border network of protected landscapes adjoining Austria’s Hohe Tauern National Park.
