Gstaad is quite an exclusive resort, but is relatively low level - the village is at about 1,000m. I once shot some photos for the local ski club at one of the slopes there and they wouldn't let anyone but the racers use the piste as they wanted to keep it in good condition. IIRC it was one of the privately owned runs, and they really didn't want this snowboarder wrecking the piste so I had to hike up to shoot photos…
Tgat slopes are closed for competition or training is normal in the alps so, nothing special about Gstaad here.
Gstaad is an interesting place. They have a yacht club but no lake for example...
