Königstuhl, Mountain summit in Gurktaler Alps, Austria

Königstuhl is a 2,336-metre summit in the Nockberge range of the Gurktaler Alps, where the borders of Carinthia, Styria and Salzburg meet. Its top is built of dark quartz conglomerates and sandstones, giving it a craggy shape unlike the surrounding grassy peaks. The Kleine Königstuhl (2,254 m) lies about 7 km north on Salzburg territory.

The mountain has served as a natural boundary marker between three Austrian regions for centuries. Its location at this triple junction made it a recognized reference point for travelers and herders moving through the Alpine area.

The name Königstuhl means "king's chair". The main summit, the Großer Königstuhl, marks the tripoint of Carinthia, Styria and Salzburg, while the Kleine Königstuhl (2,254 m) lies about 7 km north on Salzburg territory. The Nockalmstraße passes beneath western foothills and reaches its highest point, 2,049 m, at the Eisentalhöhe.

The mountain is reachable via several routes, with parking available near the Dr. Josef-Mehrl-Hütte. Optimal conditions for hiking or skiing occur during periods of stable weather when paths and slopes are safest to traverse.

The ascent to the summit gains roughly 600 meters in elevation from the mountain lodge, making it achievable for visitors with solid endurance. This moderate slope allows people to experience the high alpine landscape at their own pace.
