The Täschhorn is a mountain in the Pennine range of the Alps in Switzerland. There are no easy mountaineering routes to its summit, and it is regarded as being among the top ten 4,000-metre mountains in the Alps for difficulty, and "one of the highest, finest and least accessible 4000m mountains". It lies immediately north of the Alphubel, and south of the Dom within the Mischabel range, and is very similar in shape to the Dom when seen from the upper Zermatt valley.: 118
