Backpacking the Pasayten Wilderness

From 3-day weekend trips to week-long loops, our guide will get you inspired to grab a map, and begin charting a trip through Washington's remote and rugged Pasayten Wilderness.

For most people in Washington, the Pasayten Wilderness, nestled between North Cascades National Park on the west and Canada on the north, is just out of reach for a day hike.

But with more than 600 miles of trails crisscrossing this remote and rugged wilderness, it makes the perfect place to plan a big backpacking trip.

From 3-day weekend out-and-backs to challenging week-long loops, the trips below will get you inspired to grab a map, and begin charting your own Pasayten adventures.

Note on water: Parts of the Pasayten can lack abundant water sources, so check conditions before you go, plan your sources carefully and file a trip report when you return.

    Tips for backpacking in a Wilderness area

    • People. In general, no more than 12 heartbeats (people, dogs, horses etc.) should hike together as a group in wilderness.
    • Permits. If you are staying overnight, you will need to fill out a self-issued wilderness permit at the trailhead.
    • Pack It In, Pack It Out. When you are in wilderness areas, practice Leave No Trace ethics.

    A long weekend is the perfect chance to make the drive from either the west or east sides of the state up to Horseshoe Basin. It’s a backpacking favorite and a terrific introduction to the Pasayten. Spend a day — or a week — exploring the wonders of this alpine landscape. Climb the local peaks, check out the Canadian border monuments, or kick back and watch the marmots. At night, listen for the coyotes and count stars.

    Pair Buckskin Ridge with the West Fork Pasayten River for a superb 32-mile loop through the Pasayaten Wilderness that starts and ends at Slate Pass. As you head north on the high and wild Buckskin Ridge Trail, the vista filled with copper, gold and gunmetal peaks will pull you forward step by step. After 16 miles, you'll be close to the confluence of the West and Middle Forks of the Pasayaten River. From here, you will travel 15.5 miles through lodgepole pine and lupine meadows as the West Fork of the Pasayten River Trail carries you back to Slate Pass. You'll find dispersed campsites along the trail, as you enjoy both scenery and solitude.

    The 44-mile loop through Cathedral Pass offers some of the best scenery that the Boundary Trail has to offer. Start at the 30-Mile trailhead on the Chewuch River out of Winthrop. Hike 10 easy miles along the river, then make the climb to 6,870-ft Remmel Lake and many camps. Views of surrounding peaks will keep you entranced. Continue six more miles to circle Amphitheater Mountain, passing upper Cathedral Lake to 7,600-ft Cathedral Pass. Hike five miles east in mostly open terrain to Tungsten Mine, then close the loop by hiking six miles down the Tungsten Trail, then finish back down the Chewuch River.

Continue 3.7 miles to Peeve Pass and allow yourself two nights to camp here, as there are many excellent day hike options nearby.

    After you've taken a swim in Quartz Lake or scrambled up 8,274-foot Sheep Mountain, return to Larch Creek for your final night in the Pasayten and hike out the next day.
