Sully's is a double black diamond bump run that can be accessed by skiing See Forever from the Apex Lift (lift 6).
Off of the left side of See Forever, just past Apex is Sully's.
This run has big bumps and there are some areas where you can choose to ski in the trees.
Sully's is consistently steep from top to bottom and will pop you out in the bumpy gully of Allais Alley before bringing you to the base of the Apex Lift.
This run can be icy in spots.
Apex is never too crowded.
