Parking
East Bank Trailhead on SR 20 at milepost 138, about 33 miles east of Marblemount. The lot holds roughly 25 cars.

North Cascades National Park, WA
A remote, roughly 51-mile out-and-back to a marshy lake.
Overview
Willow Lake is the turnaround on a very long East Bank and Lightning Creek backpack. The connected mapped walk is about 25.3 miles from East Bank Trailhead to the lake’s west-end camp, or 50.6 miles round trip. A published one-way figure is 23.5 miles, so allow for the longer mapped line. This is a multi-day trip, not a day hike. The walking is mostly moderate, but the distance, a steep climb, and the remote setting make the full route hard. For a shorter outing, turn back after the Ross Lake shore or choose one of the shorter East Bank camp spurs.

Trail guide
From the trailhead, descend to the Ruby Creek bridge. The creek drew placer miners in the 1880s; a few remnants and interpretive plaques remain near the crossing. At about 2.8 miles, stay on the main trail past the Ross Lake campsite spur and the steep Little Jack Mountain turnoff. East Bank climbs through Hidden Hand Pass, then drops through forest to Ross Lake. The high bridge over Devil’s Creek Canyon is a good place to pause for the lake below.
Around mile 16, the route leaves Ross Lake and climbs steep switchbacks into the Lightning Creek valley. You get final lake views before the trail drops into a quieter, forested basin. It passes a historic log trapper’s cabin that is closed to visitors, then a log bridge and the Three Fools Creek junction. The name comes from a story about prospectors who left a Ruby Creek claim after chasing a false gold tip.
The route parallels Willow Lake, a long, shallow basin edged by marsh habitat, and reaches a spur down to a camp at the west end. It’s a quiet destination after a long approach; the lake’s wet margins support marsh plants, birds, insects, and mammals. Gray wolves have been observed in the wider area, but sightings aren’t something to count on. Dogs aren’t allowed on the trail.
East Bank Trailhead is on SR 20 at milepost 138, about 33 miles east of Marblemount. The lot holds roughly 25 cars.
