A 21-kilometer stage that presents no particular technical difficulties but requires adequate training due to its length. It starts near Rifugio Forni and arrives at the Fantelle parking lot in Madonna dei Monti. Initially take the dirt road toward the Branca refuge and at the fork turn toward Malga dei Forni, continue toward the Girella bridge until you reach the dirt road that leads to Rifugio Pizzini. An enchanting landscape and the whistling of marmots will keep you company. We descend briefly onto the carriage road and then take the mostly flat S257 trail on the right that crosses the Confinale mountain passing through the small hamlets of Raseit, Ablés and Malga Confinale. Continue to the Ables mountains, where you can stop at the farm of the same name, the Confinale malga until you reach the Baite di Cavallaro huts. Once here, after a wide panoramic view of the Bormio basin, the descent begins to the mouth of Val Zebrù and then ends the stage at the Fantelle parking lot in the hamlet of Madonna dei Monti.
