Große Schlicke, Mountain peak in Tannheimer Valley, Austria.

Große Schlicke is a 2059 m summit in the Allgäu Alps of Tyrol. Its north side consists entirely of high, near-vertical crag walls, while the south side is marked by steep grass slopes and belts of mountain pine. The summit looks across to the north faces of the Gimpel (2173 m), Rote Flüh (2108 m), Kellenspitze (2238 m) and Gehrenspitze (2164 m).

Two marked trails reach the summit of Große Schlicke, meeting about 100 metres below the top before climbing the steep southern grass slopes in switchbacks. The western trail starts at the Vilser Scharte (1817 m), reached from the Füssener Jöchl gondola above Grän or from the Vilser Alm to the north; the southern route comes up from the Otto-Mayr-Hütte in the Reintal. In winter the southern ascent is a popular ski tour.

The name "Schlicke" refers to the rock gullies and clefts of the mountain, matching the near-vertical crags of the north face. In winter the southern route from the Otto-Mayr-Hütte is a popular ski tour, while in summer two marked paths meet about 100 metres below the summit.

Hikers should wear sturdy footwear and weatherproof clothing since conditions at altitude can change quickly. The trails are marked, but it is important to stay alert and follow signage carefully, especially in foggy weather.

The two marked trails meet about 100 metres below the summit, then climb the steep southern grass slope in switchbacks; the last stretch needs sure footing. In winter the southern route from the Otto-Mayr-Hütte in the Reintal is a popular ski tour.
