Yes, their tentative opening date this year is Nov 22(ish), weather dependent. The number of trails open around NYE/Christmas is dependent on how much natural snow falls in December/if conditions support man-made snow too. We spend New Years at Deep Creek each year and spend a few days skiing. I think it was two (or three) years ago where we had about 12-15” of fresh snowfall during that time so it was great conditions. Last year was warm (relatively) and not the best conditions but it was still open.
