Ptarmigan Valley Trail

The feel

The trail starts as a wide double track and runs that way until treeline. There it turns to single track through very tall grasses, fireweed and cow parsnip, and the trail is present despite the high growth. It follows Parks Creek, tops out near the hill marked 1775' on the map, then descends into the Little Peter's Creek drainage before climbing some more along the creek.

Above the trees it opens to tundra with Knik Arm and Alaska Range views. Hikers have met a porcupine here, and the odd actual ptarmigan.

The trail is easy to follow up to the end of the valley, then it fades into open tundra. A porcupine was met on the trail.

Season and access

Open all year, with cross-country skiing in winter. Multi-use trail except for ATVs and bikes.

Mingo says

Go between June and October. The valley side can be wet and boggy in June snowmelt, so plan for mud early in the season.

Before you go

• Keep dogs on a leash; they can meet a porcupine.
• Pay the Chugach State Park parking fee before you head up.
• Do not plan to camp at the trailhead.
