Dewey Lake via Chinook Pass

Dewey Lake via Chinook Pass is a six-mile out-and-back on the Pacific Crest Trail, with about 1,270 feet of total climbing. Start at the Chinook Pass Overlook/PCT lot, join the trail by a short access path, cross the SR 410 bridge and traverse the north side of Naches Peak. The PCT climbs gradually through open flower meadows, avalanche gullies and a small tarn basin to a high point near 5,900 feet, where Dewey Lake comes into view below. Allow about four hours. You'll descend to the lake, then climb back out on the same route.

At about 2.9 miles, two unsigned paths branch from the PCT. The northeast path reaches a Dewey Lake campsite and a small beach; the southwest path goes around a smaller unnamed lake and passes two campsites. The PCT continues along the main lake's south shore, with campsites and small beaches. Most day hikers turn around in this basin. If you want Mount Rainier views, a short westward spur from the Naches Peak junction climbs about 100 feet to a viewpoint; return to the junction before descending to the lake. The eastern stretch of a separate north-shore path is the only part of the lakeshore with Rainier in view.

Use the Chinook Pass Overlook/PCT parking area on SR 410, not the Tipsoo Lake lot. The parking area often fills in mid-season mornings. A day-use fee or accepted recreation pass is required, and a free self-issued wilderness permit is available at the trailhead. There is a vault toilet but no potable water. SR 410 closes for winter, so access is seasonal. Dogs are allowed on the PCT route to Dewey Lake; they are prohibited if you continue west into Mount Rainier National Park on the Naches Peak Loop.
