Scale of difficulty
- WT1 : Easy snowshoes hike. Less than 25 degrees incline and no steep slopes nearby. No avalanche danger. No risk of slide or fall.
- WT2 : Snowshoes hike. Less than 25 degrees incline and steep slopes nearby. Avalanche danger. No risk of slide or fall.
- WT3 : Demanding snowshoes hike. Less than 30 degrees incline and short steep sections. Avalanche danger. Low risk of slide, short slides ending without risks.
- WT4 : Snowshoes tour. Less than 30 degrees incline and short steep sections and/or crossing of slopes. Partially mixed with rocks. Not much cracked glacier. Avalanche danger. Danger of slide with injuries risks. Low risk of falls.
- WT5 : Alpine snowshoes tour. Less than 35 degrees incline and short steep sections and/or crossing of slopes and/or rock bands. Glacier. Avalanche danger. Risk of slide and fall. Fall into crevasse. Alpine dangers.
- WT6 : Demanding alpine snowshoes tour. More than 35 degrees incline and demanding sections and/or crossing of slopes and/or rock bands. Highly cracked glacier. Avalanche danger. Risk of fall. Risk of fall into crevasse. Alpine dangers.
- T1 : Hike
Well traced out path. If marked out following the FSTP convention: yellow. Flat terrain or low steepness, no risks of fall.
- T2 : Mountain hike
Path with an uninterrupted trace. If marked out following FSTP convention: white-red-white. Terrain sometimes steep, risks of fall not excluded.
- T3 : Demanding mountain hike
Path not necesserally visible everywhere in the terrain. The exposed sections might be fitted with ropes or chains. Eventually the use of the hands is required for balance. If marked out: white-red-white. Some exposed sections with risk of fall, scree, slopes mixed with rocks without trace.
- T4 : Alpine hike
Trace sometimes missing. The use of the hands is sometimes required for the advance. If marked out: white-blue-white. Terrain already quite exposed, delicate grass slopes, slopes mixed with rocks, easy névé and passing of glaciers not covered with snow.
- T5 : Demanding alpine hike
Often without trace. Some easy climbing sections. If marked out: white-blue-white. Exposed terrain, demanding, steep slopes mixed with rocks. Glaciers and névé with a risk of slide.
- T6 : Difficult alpine hike
Most of the time, without trace, climbing sections up to UIAA grade II. Generally not marked out. Often very exposed. Delicate slopes mixed with rocks. Glaciers with a high risk of slide.
