From the parking area of Niblogo (1600 m) in Madonna dei Monti in Valfurva, follow the cartroad that flatly enters the beautiful and sunken Val Zebru' arriving shortly at the locality Tre croci. From here on the left and passing several times over the stream, you enter the heart of the valley that gradually opens up, passing the characteristic nuclei of ancient huts of Zebru', Chitomas, Pramighen and Campo until arriving just beyond the wooded limit at the alpine pasture of Baita del Pastore (2166 m). Now climb above the alpine hut by staying to the right of the valley incision of the Mare' stream until it is possible to enter the wide valley in the center of the amphitheater. One continues to climb passing to the left of the evident rocky spur where the Quinto Alpini hut is located and thus enters the Vedretta di Zebru'. With a gradually semicircular progression to the right, you pass under the eastern slopes of Punta Thurwieser and southern slopes of Ortles, thus arriving at Giogo Alto where the Citta' di Cantu' bivouac is located. Bend to the right and go up as far as possible on skis the wide steep slope; continue on foot passing the terminal crevasse on the right until reaching the thin western ridge. From here, leftward briefly to the summit.
