##Ascent to the Col de la Sassière From Pierre Giret's car park, reach the Ruitor refuge, then take the path to the right, at the level of the hamlet of La Sassière, towards Lac Noir. Leave this trail around 2350 m as it approaches steep slopes leading to Lac Noir and make a slightly upward crossing to the left (wetlands, grassy hills, no paths or cairns) to reach the left side of the combe de la Sassière (right bank) under a ridge, where you will find some cairns.
Locate the clearly visible path that crosses in ascent to the right and allows you to easily pass this jump.
Higher up, cross at best an area of large boulders (a few cairns at times) until you see 3 passes.
Aim for the right-most pass, at the foot of the N ridge of the Donkey's Beak.
The leftmost pass does not allow to pass on the Italian side (rocky bars).
If you arrive by mistake at the middle pass, prefer to go back to the right pass on the French side, the Italian side being particularly scabrous. ##Descent to the lake of Saint Grat Go down the Italian side (snowy) downhill crossing targeting the less steep slopes (do not try to reach the bottom of the valley immediately: steep and unstable moraine).
Finally, reach the stream around 2650 m, and stay on its right bank to go down directly to the lake of San Grato by a half grassy half earthy croup, relatively stable.
Then reach its outlet by going around it on the right (slight ascent to cross a rocky bar) and cross it by the bridge of path 14a. ##Ascent to the Forcla di Bré pass After the bridge go up the path for a few meters to leave it very quickly on the left and start a difficult ascending crossing, towards the valley of the Forclaz du Bré (risk of falling rocks, do not drag).
Total absence of any path, cairn or mark from the bridge to the Forcla du Bré.
Then climb directly up the valley on steep and unstable slopes, remaining first on the left bank, then cross to the left before the slope rises again (old moraine) on very unstable slopes.
Cross this jump on the left side of the valley by steep but relatively more stable slopes to reach the top of the moraine to a flat area overgrown with large boulders.
Raise this valley as best as possible by pulling slightly to the right.
The final jump is ascended by a vague earthy croup that can be left to the right upwards to enjoy some more stable rocks.
Reach the flat area marking the surroundings of the pass, which is then easily reached, by bypassing the "bunker" on the right, which completely blocks it. ##Descente vallon d'Arp Vieille Go down the path on the Arp Vieille side.
Make all the bends, then, when the path definitively leaves on the right (SE) follow it again a few hundred meters (cross a talweg) before going down directly by grass slopes towards the vast flat of the valley of Arp Vieille. ##Ascent to the refuge Cross this flat at an angle, staying as far as possible at its upstream end, then go back up in front of the steep grass slopes to join the path of the degli Angeli refuge (16) Follow this path without difficulty until you reach a snake from where you can quickly reach the refuge.<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
