Nest Peak is one of the 120 true summits in Chugach Park. A lonely yet spectacular spot, the summit register shows only one or two entries per year.
The trailhead is located about 25 miles south of Anchorage along Turnagain Arm. If not meeting at to carpool, proceed to Mile 100.5 of the Seward Highway, and turn onto Konikson Road. Drive this 0.6 miles to the ample trailhead parking at its terminus. The trailhead elevation is approximately 100 feet, so we will be climbing virtually all of Nest's 5030-foot height.
We will bike the approach, heading north on a wide, gated dirt road, past the Penguin Peak turnoff and past various ATV tracks. After about a mile, we cross Penguin Creek on a vehicle bridge. Immediately, bear right onto the Penguin Creek Trail, which initially is a broad ATV track. The junction is currently marked. Follow the ATV trail two miles to its end at about the 1000-foot elevation (bearing right at another junction). The end of the ATV trail is several hundred vertical feet above (and north of) Penguin Creek. This is where we will likely leave the bikes.
Directly ahead, a trail of use leads further up the slope. It quickly emerges from the trees and begins a generally ascending traverse to the eastward across the brush and tall grass just above treeline. Leave this trail when the time seems right and hike up-slope to the southwest ridge of Nest Peak. This can be done on any of several avalanche chutes, or we can wait till the trail ends after about three quarters of a mile and ascend via the indistinct corner between the Penguin Creek Valley and the first side valley on its northern flank. Once on the 4000-foot ridge, pleasant walking along a broad crest with expansive views lifts us gently to the 5030-foot summit.
