S Face Wilson Peak Map

The South face of Wilson Peak is visible from many areas of Big Sky Resort, it looks right at you, begging to be skied. It's is a very rewarding line, achieved with relatively little effort. It is about 2500 feet long from the summit of Wilson to the bottom of the slide path, making it one of the longer continuous lines in the area. From the parking lot, the summit is only about 3.5 miles, a good portion of which is on a groomed cross country ski trail. Sometimes you may not be able to drive all the way to the trailhead, so make sure you park out of the way, and DO NOT TRESPASS. From the Trailhead, travel north and slightly downhill into Middle Fork basin. You will pass several houses along this cross country ski trail. Just past Yellow Mountain, turn east off the groomer. You will be heading up a tight canyon, it is best to gain a slight bench on the north side of this feature, about 100 feet above the creek. Keep heading slightly left with Wilson in front of you. Soon you'll pop out at the bottom of the slide path and it will be straight forward form there. You may want to boot the upper section of the face.



Steep skiing at 38-45 degrees. This requires very good technique and the risk of falling has serious consequences.
