The Apollo Ski Run is a groomed traverse leading northwest from the top of lift 4 to the Creek Trail. It's generally considered, by expert skiers, to be a simply a method of getting from point A to point B, and serves as a "collector" for many of the runs coming down from northern sections of The Ridge.
However, the Apollo ski trail does provide a groomed and reasonably gentle method for less skilled skiers to use Chairlift 4, and enjoys the views from the top of Chair 4.
