Corno di Tres, Mountain summit in Mendola Ridge, Italy

Corno di Tres rises to 1,812 meters (5,945 feet) between the Predaia High Plateau and Valle dell'Adige, marking the boundary between South Tyrol and Trentino. Its location at this border creates a natural meeting point where two distinct regions converge.

Mountain paths crossing the peak served as traditional routes connecting communities in Val di Non with those in Valle dell'Adige. These trails became important trade connections between the two valleys over time.

The peak lies on the border between South Tyrol and Trentino, and its two names reflect that: Corno di Tres in Italian, Tresner Horn in German, both taken from the village of Tres below. Signs along the marked trails carry both forms, and the summit is the highest point in the municipality of Kurtatsch on the South Tyrolean side.

The usual start is the Sores refuge at 1,205 m on the Predaia plateau; a higher car park at the Predaia refuge at 1,400 m saves about half an hour. Follow forest road 503 past the Bus del Spin clearing, where a short side path leads to the fenced Buson Acqua sinkhole, then on to Malga Rodeza at 1,570 m. The route is generally safe from avalanches even after heavy snow and is often walkable on a packed track.

The summit lies on the border between South Tyrol and Trentino and is the highest point in the municipality of Kurtatsch; on the Nonstal side it belongs to Predaia. The 360° view takes in the Fleimstal and Brenta Dolomites, the Maddalene and the Monti di Vigo.
