From the Forni, one leads to the vicinity of the small artificial barrage. Following the signs to the right for the Branca refuge, first pass a small bridge over the Cedec stream and then continue along the bottom of the valley, following a nice track always beaten on the left of the Frodolfo stream, until you reach a small plateau from where you can see the refuge above on the left. This area can also be reached by passing at the beginning of the route at the base of the small dam and skirting the Frodolfo stream on the right. You now go to the right passing a small bridge, or a little further on, with good snowfall, you can easily cross the stream. Following now some small bumps and valleys in a southeasterly direction, you arrive on the basal plateau near a small Tibetan bridge, where a little further on the Forni glacier begins. Standing just to the right of the glacier's evident median moraine, follow it almost to its end and then begin to climb to the right passing at the base of the evident rock face standing almost on the left edge of the Forni glacier. After passing a steep crevasse area you reach a wide plateau and continue in the same direction climbing another short steep section thus reaching the base of the hidden southeast couloir of the Pejo Peaks. Continue in a southerly direction passing under the north face of Punta Cadini and then heading right to Colle degli Orsi located at 3304 m elevation (lowest point in the traverse of the 13 peaks). Passing now to the right of the NE ridge, overcoming first a short steep section and then a sharp section, you arrive at the base of the short and easy N ridge of Mount Giumella. Leaving your skis at the base, you follow it easily bypassing a few small rocks to the summit.
