Take North Cascades Highway (State Highway 20) to milepost 126. Turn left on the road to the Diablo Townsite and continue for one mile. Park across the street from covered swimming pool. The trailhead is to left of the pool.

Route Description

Switchback through shady forest for the first 3.5 miles. Use caution in crossing Sourdough Creek. Efforts are grandly rewarded in the last 1.5 miles of subalpine meadow and ridge top. The last 300 yards of the climb might be confusing if the Sourdough snowfield still remains. Persistence and patience will have good results...views from the summit are spectacular ... peaks and valleys in all directions. Blue lakes, grand glaciers, and the volcanic dome of Mount Baker are highlights.

Essential Gear

Eat your Wheaties.
