Kälbelespitze, Mountain summit in Tyrol, Austria

Kälbelespitze is the 2,135 m main summit of the Kastenköpfe in the Allgäu Alps, on the border between Germany and Austria; the state line runs over the top, dividing Bavaria and Tyrol. It is built of Hauptdolomit resting on a Cretaceous base. Its twin peak, the Westlicher Kastenkopf (2,129 m), stands on the west ridge, separated by a notch of about 50 m.

The mountain first appeared on maps in 1797 with a name referring to cattle pastures in the surrounding area. This naming reflects how humans historically used the Alpine landscape for grazing.

The name Kälbeleseck appeared on Schmitt's map of southwest Germany in 1797; a 1844 boundary description records "Kalbeles = Eck = Spitz", referring to the ridge where two-year-old cattle grazed. The Austrian name Kastenkopf is also used for the peak.

Reaching the summit requires advanced hiking skills and mountaineering experience since paths are not consistently marked. Visitors should plan their ascent during daylight hours and fair weather conditions.

The peak sits on the border between Austria and Germany, creating a natural meeting point for visitors from both countries. A glacial lake lies nearby and can be spotted from elevated vantage points in the area.
