Hirli, Mountain summit in Valais, Switzerland.

Hirli is a ridge crest on the east ridge of the Matterhorn above Zermatt, reaching 2,889 m above sea level. The route to the Hörnli Hut, the starting point for Matterhorn ascents via the normal route from the Swiss side, passes just below it. A little to the east lies a rounded knoll, locally called Hörnli and also named Hirli since December 2015, at 2,775 m.

The mountain trails around Hirli developed during the early era of Alpine tourism in Switzerland, creating connections between Schwarzsee Lake and mountain huts in the region. These paths allowed visitors and climbers to explore the high mountain area more easily.

Local climbers have used this mountain for many years, and experienced guides from nearby villages still lead people along traditional routes. The mountain is part of the local climbing culture and remains important to the region.

The path to the Hörnlihütte, the starting point for Matterhorn ascents via the Swiss normal route, passes just below the Hirli ridge head. The Hirli itself is not on that trail; the nearby lower knoll called Hörnli/Hirli (2,775 m) is served by a six-seat chairlift whose base station stands about 250 metres lower than the old ski lift that ran until April 2015.

The Hirli name now applies to two points: the 2,889 m ridge head on the Matterhorn's east ridge, and a rounded knoll just east at 2,775 m, also called Hirli since December 2015. That lower knoll held a ski lift opened in 1962 with wooden pylons, replaced by iron supports in 1965 and running until April 2015.
