Hochgasser, Mountain summit in Hohe Tauern range, Austria

Hochgasser is a mountain summit in the Granatspitze group within the Hohe Tauern range, rising to 2,922 meters above sea level. The peak features steep terrain on its northern face and more moderate slopes on the southern side, with multiple routes available for ascent.

The mountain overlooks the Felber Tauern pass, which functioned as a crucial trade route between the 14th and 16th centuries connecting the northern and southern Alpine regions. This historical passage allowed travelers to cross what would otherwise be an impassable mountain barrier.

The name Hochgasser comes from a broad gully, or Gasse, on the mountain's western side. It is regarded as the home mountain of the St. Pöltner Hütte, the hut from which the normal route starts. The first ridge traverse to the Bärenköpfe, and probably also to the Hörndl, was made by Roman Majewski and companions around 1923.

The ascent begins from the Matreier Tauernhaus parking area at roughly 1,510 meters elevation. The route requires sure-footedness and comfort on rocky terrain, especially across the steeper sections.

The first traverse of the east spur was made in 1993 by A. Hölzl and R. Maurhofer, starting from the north portal of the Felbertauern tunnel; the route reaches UIAA grade V in places. The normal route from the St. Pöltner Hütte over the Alten Tauern involves short secured passages of UIAA grade I.
