(S) Leaving "Refuge du Viso", take the trail you arrived on the day before over about a kilometre.
(1) Turn right heading towards Col de la Traversette.
The pasture soon gives way to rocks, the trail continues through scree. When you get to a trail crossing, head right under a rocky ledge. A few hundred metre before the pass you'll come across the tunnel entrance. The entrance is blocked by neve until the beginning of July (2).
There's a slight aerial passage after the pass. After a good kilometre hike down, take the Sentier du Postier on the right (3).
Next, head up to Refuge Giacoletti (4).
Then, head off to the left and follow the trail leading to a mineral setting at Refuge Sella Quintino, end of today's stage.
