Glacier Peak Circumnavigation
Central CascadesBest Aug–Sep
An 88-mile wilderness loop encircling Washington's most remote volcano through alpine passes, old-growth forest, and river valleys.
About This Trail
The Glacier Peak Circumnavigation ranks among the premier backpacking routes in the Pacific Northwest. This 88.5-mile loop circles Washington's most isolated major volcano, crossing multiple high passes and threading through old-growth forest, alpine meadows, and wild river valleys. Most parties complete it in 6 to 10 days. The route starts from the White River trailhead and can run clockwise or counterclockwise.
Major highlights include Image Lake with its mirror reflection of Glacier Peak, the Suiattle River valley through towering old-growth, Fire Creek Pass with views of Kennedy Glacier, and the Napeequa Valley descent. The High Pass High Route stands as the most technical and demanding section, crossing rocky, sometimes snow-covered terrain above 7,000 feet. Early-season parties carry crampons and ice axes for this stretch. The Napeequa River ford runs swift and cold, often thigh to waist deep even in late summer.
Indian Creek presents a notorious section of overgrown brush that obscures the trail. Route-finding skills matter here and in several other sections. Alternative routes exist on the west side via the Suiattle or North Fork Sauk trailheads, and Chiwawa River approaches bypass the High Pass High Route via Little Giant Pass. Side trips to Flower Dome, Cloudy Pass, and Lyman Lakes add alpine scenery for parties with extra days. September offers the best window with cleared trails, lower stream flows, fall color, and reduced bug pressure compared to midsummer.

Safety & Considerations
Today's Hazard
- Strong sun — sunscreen, hat, and sunglasses recommended
Persistent Hazards
- High Pass High Route: unmaintained, rocky, snow/ice fields requiring crampons and ice axe early season
- Napeequa River ford: swift, cold, thigh to waist deep even late season
- Indian Creek section overgrown with brush obscuring trail
- Multiple stream crossings that rise fast in rain
- Remote wilderness with multi-day stretches between any road access
Getting There
Northwest Forest Pass required. White River trailhead holds about 20 vehicles with additional roadside parking. No restroom facilities. Extended trip parking means vehicles sit unattended for a week or more.
Primary start: White River trailhead. From Highway 2 at Coles Corner, drive north 10.5 miles on Highway 207, turn right on White River Road. Continue past Tall Timbers Ranch for another 10 miles to the parking area. Alternative western approaches via Suiattle River or North Fork Sauk trailheads add 13-17 miles. Clockwise and counterclockwise both work. Counter-clockwise puts the High Pass High Route later when hikers have trail legs.
Plan for 6-10 days depending on fitness and side trips. September offers the best overall conditions. Midsummer brings heavy mosquitoes. Check fire closures before departure since the area has active fire history. Cache food or plan resupply if adding side trips.
Recent Reports
We did Glacier Peak circumnavigation as a 9-day hike with a few long days and a few shorter days Aug. 25-Sept.
Trip Summary I completed a 7-Day Circumnavigation of Glacier Peak starting August 17th and ending on the 23rd, going Counter-Clockwise. I added side trips up to Flower Dome, Sheep Camp, Cloudy Pass, Image Lake and a portion of the Grassy Point trail.
My hiking partner and I took 6 days/5 nights to do the circumnavigation as described on WTA, clockwise from the White River trailhead. Due to rain in the forecast for Thursday and Friday, we skipped the Miners Ridge portion and just went straight from Suiattle valley into High Pass.
