From January 1st, 2022, it is mandatory for ALL skiers to have insurance coverage that includes liability for damages or injuries caused to third parties. The revision of the mountain safety code requires all minors to wear helmets and prohibits skiers from consuming alcoholic beverages.
It is mandatory to have with you the self-rescue kit composed of Avalanche Transceiver-Shovel-Probe (which can be rented if necessary, see the shops where it is available here). It is also recommended to wear a helmet (for minors, wearing a helmet is mandatory) or other active protection systems (e.g., backpacks with ABS-Airbag systems).
In case of hard or icy snow, the use of crampons is recommended.
