The Grimming rises between the Enns valley and Salzkammergut, east of the Dachstein massif, being separated from its eastern rim by the Salza Gorge.Southwest of the main summit is the Grimmingtor (Grimming Gate), a roughly 50-metre-high and 15-metre-wide recess in the rock face, capped by a 10-metre-thick rock overhang.To the east it is bounded by a large rib of rock, which is why, in certain light conditions, it has the appearance of a gate.[citation needed] Thanks to its imposing appearance, the mountain was long described as mons Styriae altissimus, the highest mountain in the Austrian state of Styria.North of the Grimming summit there is a bothy that was built in 1949 and may be used as emergency shelter in bad weather.
