We use the following difficulty levels:
- S1 - Very Easy
- Easy descent which does not require any particular technical abilities such as forest tracks for example.
- S2 - Easy
- Wide slopes which are easy to manoeuvre, maybe fairly steep (25°).
- S3 - Medium (<35°)
- Slopes up to 35° (equivalent to the steepest runs in ski resorts, on hard snow). Requires good skiing abilities in all snow conditions.
- S4 - Difficult (<45°)
- Slopes up to 45°, if exposure is low (between 30 and 40° if it is high or the passage is narrow). Very good skiing abilities are required.
- S5 - Very difficult (40-50°)
- Slopes between 45 and 50° or more if exposure remains low. From 40° upwards if exposure is high. As well as a perfect downhill skiing technique, control of nerves becomes very important at this level of difficulty.
- S6 - Extreme (50-55°)
- Above 50° if exposure is high (which is often the case) or short stretches above 55° with little exposure.
- S7 - Extreme+ (55°+)
- Stretches at 60° or more, high rock bands to jump or more generally very steep or exposed terrain.
