Started from Rifugio Valsinella and hiked up to Rifugio Casinei, then to Rifugio Brentei, then to Rifugio Alimonta, and finally up the remnants of a glacier to get to the central section of the Via Delle Bocchette (4100ft). We did a portion of this called the Via Ferrata Bocchette Centrali (difficulty 3C). The via ferrata is mostly a traverse with a lot of ladders and ledges. Then we made our way back down to Rifugio Brentei, running the last 10 minutes to barely miss a fast-moving rainstorm. Had some coffee at the rifugio then made our way back down to the start.
