Lizumer Reckner, Mountain summit in Tux Alps, Austria.

Lizumer Reckner is a summit in the Tux Alps that reaches 2,886 meters in elevation. It is the highest peak in this mountain range, located southeast of Innsbruck in Tyrol.

The Lizumer Reckner lies on the edge of the Tauern window, where Penninic nappes and possibly Helvetic nappes are exposed. Its summit block consists of serpentinite embedded mainly in radiolarite, and the surrounding area holds dolomite breccias, kalkschiefer and other Jurassic rocks. Below the summit, stone runs are interpreted as remains of a former rock glacier, with traces of dead ice.

The summit stands inside the Lizum Walchen Training Area, which the Austrian Armed Forces use for exercises; access can be closed during manoeuvres, so the military presence shapes when the mountain may be climbed. The Wattentaler Lizum below holds the Lizumer Hütte at 2,019 m, the main base for ascents from that side.

The climb begins from Lizumer Hütte at 2,019 meters and involves a trek of about 9 kilometers with roughly 867 meters of elevation gain. Plan the ascent during stable weather and bring appropriate gear for mountain conditions.

Below the summit block lie stone runs interpreted as the remains of a former rock glacier, and traces of dead ice can still be found there. The final metres to the top are fitted with simple step and hand holds and require grade II climbing.
