Best ever is probably a group trip to Whistler many years ago. We got to our condo shortly ahead of a big snowstorm which closed the road behind us overnight. We awoke the next morning to a fresh layer of powder, and nearly had the whole mountain to ourselves. The only other skiers were people who had also beat the storm just ahead of us.

Best recently was night skiing with my kiddo back in January. It was a Sunday night so we nearly had the entire hill to ourselves. The sunset and alpenglow were phenomenal. And multiple planets were out: Venus, Mars, Saturn, and Jupiter were all visible.
