When can you go mountain skiing on the slopes?

During the resort’s public opening hours (from 9 a.m. to 5 p.m.): on the specific mountain skiing routes and the slopes authorized by the resort.
Outside the resort’s public opening hours (from 5:30 p.m. to 10 p.m.): there are resorts that schedule specific nighttime mountain skiing routes.
From 10 p.m. to 7 a.m. it is prohibited to go mountain skiing, either ascending or descending, in the skiable areas.
From 7 a.m. to 9 a.m., before the resort is open, mountain skiing is permitted, except on days when the PIDA (Avalanche Intervention Plan) is triggered as a result of the conditions.
It is necessary to find out from the resort about the opening hours and slopes that you can use, as well as any restrictions outside the public opening hours.
It is very important that those engaged in nighttime mountain skiing are conscious of the danger that snowploughs pose for their safety, and above all, the cables that support them.
