The first dated discoveries of human colonization within the Kaiser mountain range date up to 5000 years back. Here, remains of stone-age hunters were found at the Tischofer cave (close to Kufstein). Further discoveries prove the presence of bronze-age settlers at the cave.
With emperor Friedrich Barbarossa acquisition of Ebbs castle and all its appropriate goods in the year 1174, it is historically proved that this action built the basis for the naming of the mountain range. Back then, the term "wilder" was used for unproductive and not cultivatable regions. The areas at the South side of the mountain adopted the Wilder Kaiser, as the mountain range was separated in 3 parts. The highest peaks are the Ellmauer Halt (2.344 m, Ellmauer Kaiser), the Ackerlspitze (2.331 m, Goinger Kaiser) and the Treffauer (2.305 m, Scheffauer Kaiser).
