Sulzenauferner, Glacier in the Stubai Alps, Tyrol, Austria.

The Sulzenauferner extends across rugged mountain terrain characterized by prominent crevasses, ice formations, and steep seracs that create challenging conditions for climbers and hikers exploring this alpine environment.

This glacier has experienced notable retreat over the past century due to climate change trends, with scientific studies documenting its gradual decrease in size and volume through decades of observation.

The Sulzenauferner is visible from much of the Stubaital and shapes how the valley is perceived; its wave-shaped icefall is the feature most often pointed out. Since around 1850 the glacier has lost length and mass, and in 2013 the ice waterfall's connection over a rock edge to the tongue melted away for good.

Access to the glacier is typically feasible during summer months via well-marked trails from the Sulzenau Hut, though visitors should prepare for variable weather conditions and bring proper equipment including crampons.

Until the early 21st century the Sulzenauferner joined the Fernerstube, a glacier flowing down from the west side of the Wilden Freiger. The two ice masses have since separated. The glacier's wave-shaped icefall, visible from much of the Stubaital, is the feature most often overlooked by visitors heading for the Zuckerhütl.
