Walk from the refuge Carducci to the nearby Giralba pass and, ten meters after the first corner, turn right and walk until you reach the path n. 101. As soon as you have passed the big cairn (pile of rocks) you can see the Busa di Dentro and the path traces on the right side of the scree. Turn right and reach the directions indicating Strada degli Alpini or Cima Popera. Enter the Busa following the traces of the path, first on the scree, then on snowfield and then again on the scree. When you see the pass Alta di Popera (mt. 2870) bend to the right and, once reached the big rock steps, follow the cairns (piles of rocks) - (maximum difficulty not higher than grade I). Keep going along the long and easy ridge until you reach the top. Difficulty EE (a short section A, first degree) about 3hrs30 from R. Carducci.
