Yellow pistes
When they’re open, yellow pistes, which are marked but not groomed, are the ideal way to enjoy riding in deep snow safely. The piste operator secures them against the usual dangers, including avalanches, but preparation and checks are limited, and there isn’t usually a final check at the end of the day. If you stray beyond the groomed pistes, you have to expect hazards such as stones, tree trunks, hidden recesses and terrain traps.
Freeriding
Areas outside the marked pistes and snowparks, especially shortcuts and off-piste routes, don’t have any markings and aren’t secured against any of the dangers you may face.
It’s difficult to assess the avalanche risk. If you want to go off-piste, it’s best to find a guide with avalanche expertise or attend an avalanche course first.
Before you set off, you need to find out what the current conditions are and what the terrain is like. You should take note of the recommendations in avalanche bulletins (e.g. on slf.ch and the White Risk app) and choose a low-risk route. Freeriders must carry emergency equipment (avalanche beacon, probe and shovel) with them at all times and know how to use it.
Risk factors
The risk of triggering an avalanche depends on the current conditions, the terrain and the behaviour of everyone concerned. Avalanches can happen on slopes of around 30° or more. The steeper the slope, the greater the risk. Skiers and snowboarders set off lots of avalanches, but there are measures you can take to reduce the risk.
