This trail begins in a rain forest climbing through avalanche tracks, following the river. Numerous switchbacks make for a hard climb ending at the Pacific Crest Trail. Splendid views and alpine meadows make it well worth the effort.

This trail begins in an old-growth forest and enters Glacier Peak Wilderness at 0.5 mile. Climbing gradually, the trail passes through a magnificent cedar forest and occasional avalanche swaths. Campsites can be found at 3.5 miles at 2800 feet and at 5.0 miles at Mackinaw Shelter at 2950 feet.

From here the trail begins climbing with relentless switchbacks gaining 3000 feet in elevation in 3.0 miles. The switchbacks seem unending, but scenic vistas begin and improve as altitude is gained. The alpine meadows and the splendid view make it well worth the effort. At 8.4 miles the trail reaches the Pacific Crest Trail No. 2000.

From here one can go north on the Pacific CrestTrail to Red Pass and beyond, or make a loop by taking the Pacific Crest Trail south, traveling 6.5 miles to Dishpan Gap, then 11.0 miles on the Pilot Ridge Trail No. 652, returning to the North Fork Sauk Trail. Total length would be 26.0 miles. See Pilot Ridge Trail No. 652 for further information.

A Northwest Forest Pass is required for each vehicle parked at the trailhead.
