The Tribulaun Group with the three homonymous peaks Fleres Tribulaun (3,097 m asl), Gschnitz Tribulaun (2,946 m asl) and Obernberg Tribulaun (2,780 m asl) is constituted of Main Dolomite from the Triassic, derived from the sedimentation of lagoonal muds. The Dolomite was found here: the French geologist and mineralogist Déodat Gratat de Dolomieu discovered this type of rock, which until that time was unknown.
The Fleres Tribulaun is the highest peak of the Tribulaun Group and one of the main climbing mountains of the Stubai Alps. To the north the Fleres Tribulaun borders with the Gschnitztal valley in North Tyrol, and to the south with the Val di Fleres in South Tyrol - this means that the mountain is situated on the border of Austria and Italy. The Fleres Tribulaun is marked by deep fissures and steep rock faces.
The normal route takes from Fleres in the South Tyrolean Alta Valle Isarco to the Sandjoch saddle and through a gorge in a south-easterly direction to the peak. The tour is indicated with the III° degree of difficulty and is not difficult in terms of climbing technique, but must not be undervalued due to rock slide. Climbing equipment is absolutely essential, an alpine guide is recommendable. If you do not want to scale one of the peaks, you can also hike to the Cesare Calciati al Tribulaun mountain hut (2,369 m asl).
