Picco dei Tre Signori/Dreiherrenspitze North-West Ridge

Picco dei Tre Signori (Dreiherrenspitze) is a mighty and complex peak, the highest one of the whole Alpi Pusteresi, lying on the boundary ridge between Italy and Austria and rising at the head of Valle Aurina/Ahrntal, the Northernmost valley of Bolzano Alto-Adige province. This beautiful mountain, often attended along both the two Normal routes situated on the West side (Valle Aurina, Italy) and on the South-East side (Maurertal, Austria), shows in the Italian side a fine and long ridge facing North-West. The route running on this ridge is a classic and very interesting ascent, one of the finest routes of the whole group, involving a various ascent inside a wild and superb environment. The route can be approached from Rifugio Brigata Tridentina, Valle Aurina/Ahrntal.

Dreiherrenspitze North-West ridge, running on the boundary ridge between Italy and Austria, is a complex route, involving both rock and ice climbing.

Part I – Scrambling approach from Rifugio Brigata Tridentina m. 2441 to the Grasleitenschartl m. 2901

The Grasleitenschartl m. 2901 is a narrow rocky notch having an interest exclusively alpinistic lyging between Cima di Campogrande/Grasleitenkopf to North and Costa di ampogrande/Grasleitenschneide to SE. From the shelter take the marked path to the Vedretta di Predoi/Prettaukee; a bit before reaching the glacier, leave the main path and turn to left (East), scrambling up on scree and steep snow-fields and heading towards the upper saddle. Last meters are done climbing carefully a short but crumbling and sometimes snow-covered slope exiting on the boundary notch of Grasleitenschartl m. 2901. Another longer option to get the notch is climbing the rocks on the right.

Part II – Climbing section from Grasleitenschartl m. 2901 to the Summit snow-shoulder m. 3150

From the Grasleitenschartl m. 2901 head towards SE (left) climbing without particularly difficulties the first section of the boundary ridge, at first keeping yourself mainly on its edge. When the ridge is becoming steeper and more difficult, you must skirt it keeping a bit on the Austrian side (left), reaching a small terrace below a steeper and slabby rocky pillar (peg). Climb it slanting right, then return left on the edge of the pillar (UIAA III and III+). Up the edge on easier rocky steps (UIAA II), getting the summit of a rounded ice-cap at 3014 meters of quote. Downclimb the airy rocky walls below your foot or make one rap (one anchor in place) getting to a deep and narrow rocky notch below a rocky ridge. Up the ridge with pleasant climb (UIAA II and III), getting to the upper snow shoulder at 3150 m.

Part III – Ice -climbing section from the upper snow-shoulder m. 3150 to the summit of Picco dei Tre Signori/Dreiherrenspitze m. 3498

From the snow-shoulder traverse the summit of Costa di Campogrande m. 3266 and carry on the snowy NW ridge of Picco dei Tre Signori reaching the bottom of a wide and steep 100 meters high ice-slope. Climb it, heading towards a rocky and scree ridge, rising to a snowy terrace. Up a another easier ice-slope, then climb the last easy rocky steps leading to the superb summit.

Part IV – Descent on Picco dei Tre Signori/Dreiherrenspitze Italian normal route

The descent is made following Picco dei Tre Signori Italian normal route. From the summit downclimb on easy rocks getting to the wide and snowy SW shoulder of the peak. Here (at about m. 3335) head to right – facing out – following towards SSW the track leading to the Rif. Brigata Tridentina, the starting point, while the left track (towards NNW) descents to the Rif. Giogo Lungo. After an exposed traverse on a wide snow-slope, downclimb on a steep ice-slope, ending at a huge bergschrund.

Turn to right to get the saddle named Lahnerschartl m. 2837, beyond which carry on traversing a second glacier, the Vedretta di Predoi/Prettaukees and reaching the moraine.
