From the Christmas run, follow the right edge about 100 yards, past Riva Glade, until an island of trees is in the middle of the run. Dive into the woods here, but stay quite close to the run. The fall line will tempt you to go right. This works, but it's quite steep and the trees are very dense. The better line keeps to the left, so that you can almost see the Christmas run through the trees.

After a while, give in to the right-pulling temptation and enjoy wide-open, low angle trees until you dump out at a road. Cross the road and continue down similar terrain until you reach a second road, which you'll take to the left and hit the bottom of the Avanti lift.
