Gstoder, Mountain summit in the Murberge, Salzburg and Styria, Austria

Gstoder is the highest summit of the Murberge at 2,140 m, on the border between the Salzburg Lungau and Styria; the municipal areas of Tamsweg, Ranten and St. Georgen am Kreischberg meet here. Its pyramidal peak is built of mica schist, and just south of it lies the high plateau above the treeline with the Dörfler Alm (1,987 m) and Payeralm (1,966 m).

The summit lies on the border between the Salzburg Lungau and Styria, on the territory of Ranten, St. Georgen am Kreischberg and Tamsweg. Because of its position at the eastern end of the Lungau it is also called the "Grenzwächter" (border guard). The Dörfler Alm just south of the peak marks Salzburg's easternmost point.

The alpine meadows around Gstoder show traditional mountain farming with places like Dörfler Alm and Payeralm, where local herders still bring cattle up for summer grazing.

A hiking trail of about 4.6 kilometers leads to the summit from St Ruprecht ob Murau, with parking available near the Koasahütte at the trailhead. The route is well-marked and requires basic hiking experience.

The Gstoder is linked to the higher Schladminger Tauern only by the low valley watershed of the Murparalleltal near Schwarzenbichl at 1,234 m, which is why its isolated position allows a wide panoramic view. Just south of the summit, on the Dörfler Alm, lies the easternmost point of the state of Salzburg.
