McGregor Mountain Trail
What to Expect
Safety Advisory
The upper third of the trail crosses steep, exposed terrain with significant drop-offs and no guardrails. Loose scree near the summit demands careful footing — a stumble here has real consequences.
Snow lingers on the upper slopes well into July most years, making route-finding difficult and adding slip hazard on steep traverses. Microspikes and an ice axe are not overkill for early-season attempts.
Afternoon thunderstorms are common in summer, and the exposed summit ridge is the last place you want to be when lightning rolls in. If clouds start building by early afternoon, turn around.

Pro Tips
Start at first light — you need every hour of summer daylight for this one, and the lower elevations turn into an oven by midday. A 5 AM start keeps you in shade during the steepest forest sections.
Carry at least three liters of water and a filter. Reliable water sources thin out above the tree line, and the upper half of this trail is fully exposed with no shade and no creeks to count on.
The old lookout foundation at the summit makes a perfect lunch spot with wind protection on the north side. Spend time here — the views into the heart of the North Cascades backcountry rival anything you'd see from a helicopter tour.
