FATMAP difficulty grade
From the car park of Tignes les Boisses, the end of the valley is visible on the right of the Tignes slopes.
Go back up the beginning of the black slope of the Vallon de la Sache.
The beginning is steep.
When the terrain becomes less steep, cross to the E to reach the Sachette stream.
Climb a steep slope to reach the chalet de la Sache d'en Haut, then continue to the Lacs de la Sachette (the largest can be dry in summer).
From the lakes, go up the valley to the Col (steeper at the end).<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
