Upper Chillin' (Expert) is largely considered an expert run and one of the more challenging DH tracks on the mountain. Steep, rocky, rooty, loose and raw, very little machine work was performed on this trail and it is a downhiller's delight. Very steep and very rough, don't let the name fool you—you won't be chillin' on this trail.
Lower Chillin' (Advanced) is a machine-built and is reminiscent of a supercross course. Although it is only single black, don't let the rating fool you—there are some huge line options on this trail. Although relatively short (approximately 1.5 minutes), it is an action packed and will push you to your limits. A nice finish and complement to Upper Chillin'.
