1st day: from Valnontey to the Erfaulet bridge and then to a well indicated fork. Follow the path on the left and to the right of the little stream, towards the crest of a moraine starting from the rampart's shelf. Continue to the grassy hummock called Barma des bouquetins (2689m) and then to a rocky hummock. Follow the relief leading to a snowfield and at its end, on the left, you can see an inviting ledge. Go as far as its end and then up to the left to the traces of a path. Go to the right in order to reach a subsidence. Moreover, continue to the opposite side and up to a glacial shaped basin within two spurs. Cross diagonally rightwards the shaped basin to reach a clearly visible canal made of rocks and dirt. Go beyond this obstacle to the ramparts' top where the Pol bivouac is situated, at 3183m (6 beds), and then to the Gerard-Grappein bivouac.
2nd day: from the bivouac up to the Tribolazione Glacier south-east, passing close to the rocks at 3361m. After to have reached the glacier's upper elevated plain, continue at the base of the mountainside substaining the Cresta Gastaldi and then to the glacial passage going up to the Colle dell'Ape, 3869m. Afterwards, up to the eastern crest of the Roc (4027m) and, almost at its end, move rightwards to enter the runnel of the Colle Vaccarone, rather easily reachable. From the pass down to the Grand Pradis' glacier and then towards the top along the normal way of Valsavarenche, up from the Vittorio Emanuele II and Federico Chabod huts.
