Penguin Peak Trail

The feel

The trail leaves the Bird Valley trail system and climbs quickly through alder thickets, up the central trough of a large avalanche chute. It is short but steep and less developed than the valley trails.

In just under 1 mile it pops above tree line and emerges into the alpine, with views of Turnagain Arm and the lower valleys. The summit of Penguin Peak is 4,305 feet, and the north face beyond it is near sheer.

What to expect

Route and terrain

Out and back, rated hard, with 3200 to 4200 ft of gain. The trail starts 0.5 mile up the Bird Creek trail, climbs through alder thickets, then opens into alpine.

Time

About 5 hours.

Parking

Park at the Bird Valley Trailhead, about one mile from the highway on Konikson Road. Parking is free.

Fees and passes

No fee at the trailhead.

Hazards

The trail climbs an avalanche chute, and cornices can cling to the ridge well into June. Bears are abundant in this salmon spawning area.

Season and access

Cornices along the ridgeline can cling to it well into June.

Mingo says

Wait until the ridge cornices have fallen, since some hang on well into June. Check the ridge above before you climb far.

Before you go

• Carry a satellite phone and file a trip plan with a friend.
• Watch for bears, which are abundant in this salmon spawning area.
• Watch on the right, about 0.5 mile up the Bird Creek trail, for the start of the Penguin Peak Trail.
