Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs, etc) but only the consequences of the skier falling.
Low Exposure (E1): Exposure is limited to that of the slope itself. Getting hurt is still likely if the slope is steep and/or the snow is hard.
Medium Exposure (E2): As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.
High Exposure (E3): In case of a fall, death is highly likely.
Extreme Exposure (E4): In case of a fall, the skier faces certain death.
From TSA lift you go above the restaurant going towards the mountain you see in front, the Petit Bonvin.
Here you need to walk, not as far as the rocks, but around 100 m up.
Then you can do a diagonal to finish next to the rocks of Petit Bonvin.
There you will find a couloir of about 40 meters, which leads to an open run.
You have different options here.
The best one is all the way down and when you see some cliffs on your left you will go above them.
After this you will cross a path and go to an open forest to finish in an open area where you will see some chalets.
Here you join the Faverges off piste line, until you get to Aprili slope.
Follow the slope all the way down to the bus stop at the base.
There is a bus every 15 min which take you to Barzettes lift.
