K2, Mountain peak in Landeck and Imst Districts, Austria

K2 is a 3,000-metre summit in the Ötztal Alps, standing in the Kaunergrat ridge above the rear Pitztal between the Löcherkogel (3,324 m) and the Rostizkogel (3,394 m). Its eastern slopes are covered by the Löcherferner glacier, and the Rifflsee, the largest lake of the Ötztal Alps, lies at its eastern foot. The peak is usually climbed from the Rifflsee via the Mittlerer Löcherferner.

The name K2 is a recent coinage, absent from earlier editions of the Alpine Club guide "Ötztaler Alpen"; it comes from the peak's resemblance to the Karakorum K2. The summit is a minor three-thousander, lower than its neighbours Rostizkogel (3394 m) and Löcherkogel (3324 m), so maps usually mark it only as a survey point rather than by name.

The name K2, adopted only recently and absent from older editions of the Alpine Club's Ötztal Alps guide, comes from the peak's resemblance to the K2 of the Karakorum. In late winter, ski tourers consider it a rewarding objective, and it is heavily frequented on fine-weather weekends.

Climbing this peak requires advanced mountaineering skills and proper safety gear, with summer being the optimal season for attempts. During warmer months, conditions are most favorable and daylight hours allow time for safe ascents.
