Big Beaver Trail

Big Beaver Trail is one of the North Cascades' great hidden corridors — a low-valley route that follows Big Beaver Creek from Ross Lake deep into some of the most ancient old-growth forest left in the Pacific Northwest. You'll start from the Ross Dam Trailhead, which already feels remote since getting there requires either a boat shuttle across Diablo Lake or a steep descent down the Ross Dam Trail itself. From there, the path winds through cathedral groves of western red cedar — some trees wide enough that three hikers linking arms couldn't wrap around them. The trail is mostly gentle and forested, with the creek as your companion, though it can be brushy and muddy in sections. Beaver Pass, the ultimate destination for backpackers, sits in a broad alpine meadow ringed by glaciated peaks. This trail rewards patient hikers who measure a day in quiet moments, not vertical feet.
