Get to the refuge (Summer)

Climb by Tré-le-Champ

Time: 3h30

Distance: 4.61 km

Elevation Gain: 992 m

Difficulty: Difficult

At the Tré-le-Champ car park, take the signposted path “Lac Blanc 2 h 45” which dives into the forest. After a fairly long series of
switchbacks, follow the direction of Lac Blanc at the sign. After a new series of laces, the path leads to the imposing Argentiere Aiguillette.

To continue, we will have to use the ladders fixed to the rock walls with caution; no problem, the ladders are not exposed to vacuum, only
the passage on the scale requires more attention. After this little getaway, continue the winding path until you reach a fairly massive cairn
accompanied by Tabonneaux.

Continue towards Lac Blanc. The path will pass near the Lacs des Chéserys: do not hesitate to stop there to admire the panorama of the
Mont Blanc range.

Further on, the path invites you to take a last ladder that is easier to climb than the first. A final climb in large boulders will reach the
Chalet du Lac Blanc and the lake

A little further on, we reach a promontory overlooking the Argentière Glacier. The path continues on the grassy slope to finally lead to a flat area allowing you to admire the Mont-Blanc range. Lined with regular cairns, the path finds of Tré-le-Champ at the level of the Lacs des Chéserys.
