Grosser Peilstein, Mountain summit in Waldviertel, Austria

Grosser Peilstein is the highest point of the Ostrong ridge and of the entire southern Waldviertel, at 1,061 m above sea level. Its summit dome lies in the district of Melk in Lower Austria; the Kleine Peilstein (1,024 m) stands about 300 m to the northeast, and the Kaiserstein (935 m) is a further rise on the same ridge.

The Kaiserstein, a 935 m summit on the Ostrong ridge, is named after Emperor Franz I, who liked to climb the peaks around Münichreith from his summer residence at Schloss Luberegg. The route from Münichreith over the Kaiserstein to the Großer Peilstein runs for a long stretch along the ridge and takes 2½ to 3 hours.

The Kaiserstein, a 935 m rise on the Ostrong ridge, is named after Emperor Franz I, who liked to climb the peaks around Münichreith from his summer residence at Schloss Luberegg. The Kleine Peilstein, 300 m northeast of the main summit, carries a large summit cross and a summit book that walkers sign.

The mountain is accessible through several marked trails of varying difficulty that can be reached from different locations in the region. Hikers should check weather conditions and wear sturdy footwear, as trails vary in their surface and steepness.

The Kleine Peilstein, 300 metres northeast and 37 metres lower, has a larger summit cross and a summit book, and its rock spur offers a wider view than the main summit, including toward Laimbach am Ostrong. Many hikers pass it on the direct route from Laimbach via the Schneidermauer.
