The Hinteres Sonnwendjoch in the Austrian state of Tyrol is a mountain, m (AA), and the highest peak of the Mangfall range, a subdivision of the Bavarian Prealps. Because the Brandenberg Alps to the south are lower, its summit offers outstanding views of the Central Alps despite its low elevation. The Hinterer Sonnwendjoch drops away steeply to the north into the Grund. The summit is made of main dolomite and, on the south side, of plattenkalk.
