The North Fork Sauk Trail makes for a lovely late fall jaunt into the sprawling Glacier Peak Wilderness. Following a glacier fed river deep into a remote and dramatic valley, the trail traverses some of the grandest and oldest trees in the North Cascades. The trail is mostly used by backpackers to access the Pacific Crest Trail. But a day hike of a mile or two or ten will satisfy. And this trail is often pretty quiet in the fall and spring.

The trail immediately begins in a grove of giant cedars. After a couple hundred feet the trail for the Red Mountain lookout (a nice side trip) departs left. The lookout was removed in 1967, but the site still provides some decent views of the Monte Cristo Range. Continuing up valley, the North Fork Sauk is frequently out-of-sight but always audible. At 2.1 miles reach a junction with the Pilot Ridge Trail heading right to glorious high-country meadows. It’s a strenuous journey that begins with a potentially challenging ford of the river.

Barely standing–you may want to rely on your tent instead for shelter.

The North Fork Sauk Trail continues through more impressive groves of ancient conifers. In fall, vine maples add touches of gold. In late spring the forest floor is lined with yellow violets, purple bleeding hearts and white and pink trilliums. At 4.5 miles reach a backcountry camping area near crashing Red Creek. This is a good spot to turn around, but you can easily continue farther.

Cross raging Red Creek on a steady bridge and after passing through a large brushy avalanche zone reach the still standing Mackinaw Shelter in big timber at 5.8 miles.  Forget about staying in the shelter unless you like Hantavirus. There are plenty of good campsites around the shelter. Spend the night or start heading back. The trail continues, eventually reaching the Pacific Crest Trail and some excellent backpacking destinations.
