Spechhorn, Alpine summit in Valais and Piedmont, Switzerland and Italy

Spechhorn (Italian: Pizzo di Antigine) is a 3,189-metre summit in the Weissmies group of the Pennine Alps, on the border between Switzerland's Valais and Italy's Piedmont. Its northern side overlooks the Mattmarksee, and the summit sends out three ridges: south to the Joderhorn, east to the Ofentalhorn, and northwest over the Spähnhörner. The mountain is barely glaciated, with only the small Ofentalgletscher northeast of the summit.

The mountain has long served as a natural border marker between Switzerland and Italy. This geographic position influenced how the territorial boundaries in this Alpine region took shape over time.

The Mondellipass below the south ridge, the lowest notch between the Spechhorn and the Joderhorn, was used by smugglers in the past; two late Roman coins were found there. The pass is reached from the marked trail toward the Modellipass.

The summit is accessible from both the Swiss and Italian sides via marked trails and is best visited between July and September. Good Alpine experience is needed for the ascent, and weather and conditions should be checked before attempting the climb.

The mountain displays different geological formations on its north and south faces, shaped by different tectonic processes in the Pennine Alps. This geological contrast makes it a place where visitors can observe how these mountain-building forces worked.
