On a pow day... Peak to creek is insane.. also I highly reccomend getting the first tracks breakfast. Order before getting there cuz it will sell out. It will get u on the mountain an hour before everyone else plus breakfast included. For like $25 . Worth it if it snows the night before
First tracks is always worth it, of course better with a heavy snowfall, you've come a long way so max your hill time.
Definitely do the peak to creek run but don't waste it on a powder day.
On powder days stay at the top of the mountain in the high alpine and the bowls on the whistler side, or blackcomb glacier. Seventh heaven is a must do as well. Symphony and harmony also great.
