Wilderness Peak Loop
Issaquah AlpsBest Year-round
A forested Cougar Mountain loop with old-growth conifers, boardwalk bogs, and a summit bench minutes from the Eastside.
About This Trail
Wilderness Peak sits in the heart of Cougar Mountain Regional Wildland Park, one of the largest urban wildland parks in the country. The trail climbs through stands of old-growth Douglas fir and western red cedar, weaving past mossy boulders the size of small cars before reaching the forested summit. A bench and register mark the high point, though the views stay mostly filtered through the canopy.
The route descends through Shy Bear Pass and crosses Big Bottom Bog on a narrow boardwalk, where skunk cabbage and marsh plants fill the low ground. Seasonal wildflowers line the trail in spring, including trillium, violets, and avens. For a longer outing, an extension loop adds about 3 km and visits Doughty Falls and the Long View Peak viewpoint, which opens up a much broader panorama.
This trail sees mud year-round in the lowland sections, especially near the bog. The forest canopy keeps things sheltered in wet weather, making it a solid rainy-day option close to town. Expect the small trailhead lot to fill on weekends by mid-morning, but overflow parking sits across the street.

Persistent Hazards
- Muddy sections year-round near Big Bottom Bog
- Narrow boardwalk crossing can be slippery when wet
Getting There
Small lot fits about 12 cars. Overflow parking available across the street. No pass required. Portable toilet at trailhead. Dogs allowed on leash. Park open 8 AM to dusk.
From I-90 Exit 15 near Issaquah, head south on Highway 900 for about 3 miles. Watch for the blue sign reading "Cougar Mountain Regional Wildland Park / Jim Whittaker Wilderness Peak Trailhead" and turn uphill into the lot. Paper trail maps available at the information board and downloadable from King County's website.
No time pressure here. Weekday afternoons stay quiet. Weekend mornings fill the lot by 10 AM, but the trail itself absorbs crowds well since most people spread across the park's network.
