Wassertalkogel, Alpine summit in Tyrol, Austria.

Wassertalkogel is a 3,252 m summit in the Geigenkamm ridge of the Ötztal Alps, south of the Puitkogel. Its broad summit plateau, marked by stone cairns, drops in steep but climbable blocky flanks west into the Pitztal and east into the Pollestal. The Rheinland-Pfalz-Biwak, a shelter with 9 sleeping places, stands at the western edge of the plateau.

The first documented ascent took place on August 29, 1895, when mountaineer Rudolf L. Kusdas reached the summit. This early exploration marked the beginning of modern climbing history for this peak.

The summit takes its name from the Wassertal, a steep gorge northwest of the peak where water rushes down. The mountain itself has no lake or spring on its plateau; the name points to that neighbouring valley, not to the summit terrain.

The Mainzer Höhenweg crosses the summit plateau and is secured with fixed ropes at grade I sections. The Rheinland-Pfalz-Biwak, a shelter with nine sleeping places, stands at the western edge of the plateau. The marked route from Mandarfen passes avalanche barriers and a metal cross visible from the valley before climbing steep grass and scree slopes.

The Rheinland-Pfalz-Biwak stands at the western edge of the summit plateau, a roomy bivouac box with nine sleeping places. It is the last three-thousander crossed on the Mainzer Höhenweg before reaching the Rüsselsheimer Hütte. The summit plateau itself is broad and marked with stone cairns.
