Pioneer Ridge (Austin Helmers)

The feel

The trail begins in forest and traverses the northeast slope of Pioneer Peak. The first stretch is the wettest, with small rivulets crossed on short boardwalks or a simple step. At 2,000 feet it switchbacks, then opens onto a treeless ridge, and three picnic tables along the way mark your progress.

At 3,200 feet you crest the ridge, and the top of Pioneer Ridge Trail sits at 5,300 feet. Views reach the Knik Glacier, the Matanuska River Valley and the Talkeetna Mountains. Past the ridge, another 1.5 miles leads to the south summit at 6,398 feet. That push sometimes means scrambling on all fours over loose rock, with steep drop-offs and unclear paths.

What to expect

Route and terrain

Out and back, 9.6 miles round trip to the summit ridge or 12 miles to the south summit, with 5200 to 5,330 feet of gain. The tread is dirt and rock, 1 to 2 feet wide, with fiberglass markers every 200 feet guiding the way up to the ridge.

Time

About 8.5 hours, so plan on a full day.

Parking

A parking area on Knik River Road, 3 1/2 miles after the left turn off the Old Glenn Highway. The trailhead sign sits parallel to the road and is easy to drive past.

Fees and passes

$5 or a Matanuska-Susitna Borough parking pass.

Dogs

Keep dogs on leash and/or under your control. Beyond the ridge, dogs become problematic.

Hazards

The trail tends to be muddy and slippery after a rain or frost. Weather can change quickly at higher elevations, often bringing fog and low visibility. Bears and moose live in the area. Beyond the ridge, loose rock and steep drop-offs.

Bathrooms and water

Public toilet facilities at the trailhead.

Season and access

Typical season is June to September. From Palmer, go southeast on the Old Glenn Highway, cross the Knik River bridge (approximately 9 1/2 miles from Palmer), then turn left on Knik River Road.

Mingo says

Pick a clear day between June and September. Denali shows from the top only when the sky is clear. Fog can roll in fast up high, so turn around if visibility drops.

Before you go

• Carry a Matanuska-Susitna Borough parking pass or $5 for the lot.
• Plan on a full day for the round trip.
• Allow time for the descent, which is slower and more dangerous than the climb on scrambling terrain.
• Call the MSB Parks and Outdoor Recreation Division at 745-9690 for trail information.
