You start at the parking lot above the valley station of the cable car. Afterwards turn left into the valley. The lower part is mostly filled up by a big avalanche, so in spring you use a path on the left side of the creek, which mostly leads up snow-free, where the valley gets wider. Follow the middle of the valley always upwards until you reach a plain under an icefall. Starting on the left side of this plain, one reaches a steep slope and over this to the right to the glacier (3050 m).Always stay on the left edge of the glacier, always following a flat path towards Rosimjoch (attention: crevasses on the right!). In front of the yoke there is a ramp to the left under the south-eastern ridge of the Cima Vertana. A short steep right ascent onto this ridge. The summit is visible quite far back.Then a large ramp flat left under the crest leads far into the basin. The last steep part may be reached without skis. The descent is on the way back.
