Kremsmauer, Mountain summit in Upper Austrian Prealps, Austria.

Kremsmauer is a mountain summit in the Upper Austrian Prealps reaching about 1,600 meters in elevation. The peak spans across Klaus an der Pyhrnbahn and Micheldorf, featuring a ridge walk with secured climbing sections and open views toward surrounding ranges.

The sources record no founding date, climbing history or Alpine-club development for the Kremsmauer; the documented facts are geographic. Its highest point reaches 1,604 m above sea level, and the ridge between the main summit and the Törl (1,457 m) carries the triple watershed of the Alm, Krems and Steyr, the first two draining to the Traun and the last to the Enns. The Krems rises at the Kremsursprung on the northeast side of the wall, and the Kirchmauer with the Brennet (1,249 m) forms the southeastern spur.

The name Kremsmauer refers to the Krems river, which rises at the Kremsursprung spring at the foot of the wall on the northeast side. The ridge between the main summit and the Törl carries the Alm–Krems–Steyr triple point at about 1550 m: the first two rivers flow to the Traun, the Steyr to the Enns.

The hike takes about three and a half hours with roughly 1,100 meters of elevation gain over about 12 kilometers of trail. Proper footwear and sure-footedness are important, especially through the secured climbing sections.

On the ridge between the main summit (1604 m) and the Törl (1457 m) lies the Alm–Krems–Steyr triple point at about 1550 m: the first two rivers drain to the Traun, the Steyr to the Enns. The Krems itself rises on the northeast side at the foot of the wall, at the Kremsursprung.
