The Thaneller, above Heiterwang in the Tyrolean Zwischentoren region, is one of the most striking mountains in the area. While in summer the ascent from Berwang is a rewarding hike and the approach from Heiterwang via the Rietzlersteig offers a varied mountain tour, in winter the north side of the Thaneller turns into a true playground and ideal training ground for winter mountaineering and north face climbing. With around 1,400 metres of elevation gain, climbing sections up to grade three, steep firn and snow passages, and short ice steps, the face is a real alpine challenge in every respect. It offers countless possibilities to choose a more or less demanding line to the summit — individually adapted to the current conditions. And best of all: at this time of year, you often have the mountain almost entirely to yourself. The tour can also be perfectly integrated into a multi-day winter mountaineering programme. With the Rubihorn North Face, the Geierkopf North Face, or a winter ascent of the Eisenzeit on the Zugspitze, the surrounding region offers many additional and more demanding options.
