What to Expect

Starting from the Fireweed Camp trailhead along the Stehekin Valley, this trail climbs steadily through old-growth forest before opening into subalpine meadows that explode with wildflowers in midsummer. The route follows a well-worn path shared with stock animals, so expect wider tread and the occasional evidence of horse traffic. The seasonal bridge at Rainbow Ford is the crux — it gets pulled every fall, meaning early-season and late-season hikers face a potentially dicey creek crossing. Beyond the ford, the trail grinds upward through increasingly dramatic terrain toward McAlester Lake, a classic North Cascades alpine gem ringed by rugged peaks. Push further to South Pass at roughly 6,300 feet and you're rewarded with sweeping views into the heart of the range. This one is for hikers who don't mind earning their scenery the hard way and appreciate backcountry solitude that the more famous Cascade Pass crowd will never find.

Safety Advisory

If the Rainbow Ford bridge has been removed for the season, the creek crossing can range from ankle-deep to waist-deep depending on snowmelt — trekking poles and water shoes are essential, and turning back is the smart call if the water is fast and above your knees.

Snow lingers on the upper sections and South Pass well into July in heavy snow years. Navigation above treeline can be tricky in fog without the trail fully melted out — carry a map and GPS, not just your phone.

This is prime black bear country and grizzlies have been documented in the North Cascades. Hang food properly or carry a bear canister, and make noise on blind corners through the dense forest sections.

Pro Tips

Trail Tip

Check with the Chelan Ranger District on the status of the Rainbow Ford bridge before you go — it typically goes in by mid-June and comes out in October, but timing varies with snowpack and funding.

Trail Tip

This trail is accessed via Stehekin, which means you're taking the Lady of the Lake ferry or a floatplane to get there. Plan your logistics around the ferry schedule and build in buffer days in case of weather delays.

Trail Tip

McAlester Lake makes an outstanding overnight destination with designated backcountry campsites — grab a permit from the Wilderness Information Center in Marblemount and you'll have one of the most peaceful alpine camps in the North Cascades.
