Descent:
"Getting up is only half the battle" (Confucious Caeser Messner, ca. 1453)
Due to the epic size of the South Face of Marmolada, the descent (in decent time present its own various difficulties.
Cablecar from Punta Rocca / Serauta --> Malga Ciapela. If you are fast, up until 4pm you can catch this cablecar from Punta Rocca back down.
Hike down towards the middle cablecar station (Serauta). Shortly before reaching it, turn left onto the ski slopes. Follow them up to the Fedaia pass where the refuge of the same name is found (2057 Mt.). From here return to Malga Ciapela (useful to have 2 cars or hitchhiking).
