From Rifugio Coston (2661 m) the ridge appears as a succession of four peaks. The ascent, up to the third peak, develops at first on easy snow slopes on the left side of the ridge. Beyond the third peak, we traverse a large saddle and we reach the foot of the Signalkopf (3725 m), the fourth peak.
With short climb sections of grade IV, presenting several bolts in the rock, we climb over some rocky boulders and sharp ridges, allowing us to reach the top of Ortles (3,905m) in a relatively short time. .
Day 1: We leave the car at the car park by the cable-car station in Solda. Here we begin our hike following the path to Rifugio Coston along the shores of Solda river at first, and then climbing a rocky section leading to the moraine of the Solda glacier, near the middle station on the cable-car (alternatively, we can decide to ascend by cable-car and save the energy for later). Following the path along a grassy slope we climb a ridge with great views on Gran Zebrù, and we turn right in a glacier valley as we reach Rifugio Coston (2661 m).
Day 2: After an early breakfast we leave at the crack of dawn. First we walk on the Solda Glacier’ moraine, a flat section that follows the rocky flank below the Coston ridge. Then we climb over a steep scree slope as we make our way to a rock spire, which represents a II grade climb. The next section of our ascent is on snow and easy rocks, leading to the Signialkopf peak. We bear left as we descend diagonally, with an abseil down for about 20m onto a ledge, and we continue on the ridge.
An alternation of easy climbs (II and III grade), steep snow slopes (40°) and 2 climbs of IV grade (bolted) lead us to an enclosed vertical passage, after which we are finally at the top!
The descent is along the normal route, in the direction of Rifugio Pajer. The route requires careful attention as we tackle several grade II downhill climbs and a snow slopes almost 40° steep.
