(S) From the refuge, head towards the downhill ski slopes. Go up the valley along the path to the left of the slopes. The path passes through the forest before coming out again and continuing across the mountain pasture. The path will take you diagonally to your left and climb a little more steeply to a small lake on a small plateau, the Lavu d'Altore(1930m).
(1) Climb up through the scree until you reach Bocca Tumasqinesca or Col Perdu (2183m).
(2) From there, you will discover the Cirque de la Solitude.
Descend to the bottom of the cirque, taking care as the path is very steep and requires some light climbing.
(3) Once you are almost at the bottom, climb up the opposite side, where a ladder allows you to hoist yourself onto a rocky outcrop.
You will come to a small plateau before reaching Bocca Minuta (2218m).
(4) Although very short on the map, this passage takes a long time, especially if there are other people around.
Once on the other side of Bocca Minuta, descend through the slabs and boulders to reach the Tighjettu refuge (1683m) on a small plateau (E).
