It is the deepest saddle on the main ridge of the Wilder Kaiser between the Ostkaiser's Ackerlspitze in the East Kaiser and the Ellmauer Halt in the Central Kaiser mountains. Because there is a well-used route across the Ellmauer Tor with its unique setting, it is often referred to as the heart of the Kaiser. From the south, seen from the general direction of Ellmau or Going, it is the distinctive notch in the Kaisergebirge between the Karlspitzen and the Goinger Halt.
