Climbing the Dome Glacier
From Darrington, drive the Suiattle River Road (FSR 26) to the Downey Creek trailhead. The road has been closed at milepost 10.5 since December 2025 washouts, so check status first. Hike Downey Creek Trail 6.5 miles, then the brushy old Bachelor Creek trail over Cub Pass to Cub Lake and camp on Itswoot Ridge. Traverse to the Dome Glacier, climb to the notch north of the summit, and finish on an exposed Class 4 arete where many parties fix a handline. A Northwest Forest Pass is required to park. Fill out the free wilderness permit and plan 3 days.
