Hiking the Untersberg: what the cable car doesn't tell you

The Untersberg sits directly south of Salzburg, its silhouette visible from almost everywhere in the city. At 1,853 metres at its highest point (the Berchtesgadener Hochthron), it is not technically difficult by Alpine standards — but it is a real mountain, and the number of visitors who arrive unprepared because they assume the cable car makes it easy is considerable.

This is the guide I wished I had before my first Untersberg day.

What the Untersberg actually is

The Untersberg is a limestone massif that straddles the Austrian-German border, partly in Salzburg province and partly in Berchtesgaden. It is larger and more complex than it appears from the city: the summit plateau is roughly 2km across, there are multiple peaks, and the cave system beneath it (the Schellenberger Ice Cave and the Eisriesenwelt system are related formations) is extensive.

The Austrian side of the mountain — the side most Salzburg visitors approach — has a cable car from the village of St. Leonhard at the mountain’s foot, about 12km south of the city.

Getting there from Salzburg

From Salzburg Hauptbahnhof, the bus 25 runs to the Untersberg cable car station at St. Leonhard in about 40 minutes. Driving is about 20 minutes. The cable car parking area has ample space and costs around €4–6 for a full day.

The cable car (the Untersbergbahn) runs from approximately 8:30 to 17:00 (check seasonally — it closes November to late December and on days with dangerous weather). The return fare is around €23–25 per adult. The Untersberg cable car guide has the current hours and pricing.

What to do at the top: the summit plateau

The cable car arrives at approximately 1,776 metres, very close to the Salzburger Hochthron peak. From here, the summit plateau extends south and east. On a clear day, the panorama covers the Salzburg plain, the city itself (recognisable by the fortress), the lakes of the Salzkammergut, and the Hohe Tauern range including the Grossglockner to the south.

The plateau walk — a loop from the cable car station to the Berchtesgadener Hochthron and back — takes about 90 minutes to two hours and involves some scrambling on the rocky terrain. It is not technically demanding, but the altitude means the weather can change quickly, and the exposed ridge sections require appropriate footwear. Trainers are not adequate for the full summit walk.

The mountain hut at the top (the Zeppezauerhütte) serves hot food and drinks. In summer, it is busy; in early autumn, it is one of the more pleasant Alpine hut experiences in the region.

The hiking route from the valley

For visitors who prefer to walk the whole mountain, the most-used trail from the valley is the Zinkenkogel path from St. Leonhard, which gains about 1,200 metres of elevation over approximately 6km of trail. The walk up takes 2.5–4 hours depending on fitness; the descent is 2–3 hours. It is a full-day commitment.

The route passes through beech and pine forest for the first two-thirds before emerging onto the limestone karst of the upper plateau. The landscape change is dramatic — from dense woodland to open white rock with Alpine flowers in the crevices.

A few practical points for the walking route:

• Start before 9:00 in summer. The afternoon thunderstorms that develop over Alpine terrain are a genuine risk on exposed ridges above 1,500 metres.
• The summit plateau can have snow and ice patches into June. After a heavy winter, the north-facing sections may be impassable without crampons until mid-June.
• Tell someone your plans and expected return time.
• The mountain rescue service in Austria is excellent but expensive for those without Alpine rescue insurance. The ÖAV (Austrian Alpine Club) offers it as part of membership.

What you will see (and smell)

The Untersberg summit plateau has a specific character that the cable car summary does not convey: it is primarily limestone karst, which means white rock, extraordinary silence, and views in every direction without obstruction. The Gaisberg — the other major hill near Salzburg — is lower and rounder, accessible by road to the summit, and offers a different type of view. The Untersberg is more demanding and more Alpine.

On a clear day from the summit, you can see the Watzmann (the large pyramid directly south, in Berchtesgaden territory), the Hochkönig to the southwest, and on exceptional days the glaciers of the Hohe Tauern. The city of Salzburg appears surprisingly small from 1,853 metres.

In early summer, the plateau is covered with Alpine flowers — cranesbill, alpine clematis, rock roses — growing in the limestone crevices. By August, the grass is bleached by sun and the rock takes on a harsh quality. September and early October, with the first snow on the peaks further south, is when the colours are richest.

Photography and timing

The best light for photographing the city from the Untersberg is morning — the sun comes from the east and illuminates the fortress and the Altstadt spires from behind you (if you are facing northwest). By afternoon, the city is in partial shadow and haze.

The best light for photographing the mountain itself is late afternoon in September–October, when the south-facing limestone glows orange before sunset.

What to pack

The temperature at the summit is typically 8–12°C cooler than in Salzburg city, even in summer. July afternoons that reach 28°C in the city can be 16–18°C on the summit with wind. Pack a waterproof layer regardless of the forecast.

Footwear: proper hiking boots for the plateau walk. Light trainers are acceptable for the immediate cable car station area but not the summit loop. For the walking route from the valley, solid hiking boots with ankle support are required.

Water: 1.5–2 litres minimum. The mountain hut sells water but it is expensive by Austrian standards (€3–4 for 0.5L). There are no reliable water sources on the plateau.

The Untersberg vs Gaisberg

Both hills are within easy day-trip distance of Salzburg. The Gaisberg (1,287m) has a road to the summit that makes it accessible without walking; it is the easier, more accessible option. The Untersberg is a proper Alpine mountain with a proper Alpine atmosphere. If you have hiking experience and appropriate gear, the Untersberg is the more rewarding experience. If you want a panoramic view without significant exertion, the Gaisberg or Mönchsberg are simpler options.

For serious hikers: the Untersberg is a satisfying half-day or full-day objective with accessible logistics from the city. It is not the Dachstein or the Grossglockner, but it gives you genuine Alpine terrain within an hour of Salzburg’s Altstadt — which is one of the stranger and better facts about this city.
