Praxmarerkarspitzen, Mountain summit in Scharnitz, Austria.

The Praxmarerkarspitzen are two summits in the Gleirsch-Halltal chain of the Karwendel: the Western Praxmarerkarspitze at 2642 m, the highest point within Innsbruck's city limits, and the Eastern Praxmarerkarspitze at 2638 m, about 150 m to its northeast. Steep rock walls drop north toward the Hinterautal, while a marked ridge descends south into the Samertal, separating the Gamskarl cirque from the Praxmarerkar.

The first ascent was accomplished by mountaineer Hermann von Barth in 1870, marking an important early milestone in Alpine climbing history. The north wall was later named after Otto Melzer, who died during a climbing attempt in 1901.

The north face of the Eastern Praxmarerkarspitze is called Melzerwand after Otto Melzer, who died there on 6 October 1901. He and Emil Spötl were attempting the first ascent of the wall; Spötl fell, and Melzer, unable to free himself, died hanging from a piton. A memorial on the path to the Sunntigerspitze (2321 m) recalls the accident.

The usual approach starts at the Pfeishütte (1922 m) and reaches the Östliche Praxmarerkarspitze in about 4 hours at UIAA grade II. The traverse between the two summits is also grade II and takes about 15 minutes. The onward ridge to the Jägerkarlspitze is harder, grade III. The south ridge and the route over Gamskarl and the western pre-summit are grade II, the latter mainly used for descent.

The two summits are close but not identical in height: the Western Praxmarerkarspitze reaches 2,642 m, the Eastern 2,638 m, and the crossing between them is rated UIAA grade II and takes about 15 minutes. The Western peak is the highest point within the city limits of Innsbruck.
