Recreation

One of the more popular uses of the area is the hike to Notch Peak so you can look down the notch in person. The summit can be reached by following a trail from the east side of the mountain in Sawtooth Canyon. The hike is about 7.5 miles round trip (12 km), with elevation gain.

Climbing

The north face of Notch Peak is divided by a large shelf into an upper and lower wall. There are several big wall climbing routes on the limestone cliffs. ''The Swiss Route'' (never repeated), ''Direct North West Ridge'' (or ''Pillars of Faith''), and ''Book of Saturdays'' ascend the upper wall. On the lower wall ''Appetite for Destruction'' and ''Western Hardman'' at over of vertical height. Climbing on all of these routes is adventurous with rockfall hazards and loose flakes of widely varying sizes.
