Approach Prusik Peak via Snow Lakes Trail or Colchuck and Stuart lakes Trail. Both Trailheads require USFS parking permits and camping is by permit only between May 15 - Oct 15. Acquire permits at the Leavenworth Ranger Station.

For Snow Lakes approach:
Follow Icicle Rd. 4.3 miles to the Snow Creek Trail Head parking lot on the left. Follow the trail out of the parking lot past the billboard and over the creek. This trail will take you past Nada and Snow Lakes and put you at Lake Vivianne, looking directly at the south face of Prusik Peak, in about 10 miles with 5,000+ft elevation gain. Once at Lake Vivianne, follow trails up and right to Temple Lake and continue up climbers paths through boulders to the base of Prusik Peak for south face routes or hike to Prusik Pass to climb West Ridge route.

For Colchuck/Stuart Lakes approach:
Follow Icicle Rd. about 8.5 miles to Bridge Creek Campground. Find FS road 7601 at the far west end of the campground and follow it until you reach the Stuart Lake Trailhead. Hike the trail for 2.5 miles and take an obvious left leading to Colchuck lake. Once at the lake, boulder hop to the south end of the lake, passing underneath Colchuck and Dragontail Peaks, heading for Aasgard pass to the left of Dragontail. Follow Aasgard to its top on a well maintained trail. From the top continue on the Upper Enchantments trail until Prusik Peak is visible and choose whether to approach via Prusik Pass or Lake Vivianne.

Note: Approach from Snow Lakes tacks on an additional, approximate 2 miles and 1000ft of elevation gain, but is much more gradual and consistent. I.e. Aasgard pass gains 2.2k ft elevation in .8 miles. Snow lakes trail is also much more shaded on hot, sunny approach days.
