Mount Pilchuck State Park Mining Road
1920s mining road to Cascade granite boulders
This abandoned mining road climbs 3,200 feet through second-growth forest to reach the granite boulder fields below Mount Pilchuck’s 5,324-foot summit. Built in the 1920s to access copper and gold claims, the upper sections deteriorated into a boulder-strewn technical challenge that ends at the old fire tower ruins with commanding views of the North Cascades and Puget Sound.
Difficult rating demands aggressive tread, skid plates, and articulation for the granite boulder section above 4,000 feet. Stock vehicles turn back at the first major rock garden. Best accessed May through October; winter snow closes the route entirely. No permits required but parking fills fast on weekends. No camping on-site, but dispersed sites available in nearby Mount Baker-Snoqualmie National Forest. This route rewards technical driving skills with one of Washington’s most dramatic alpine vistas.

Frequently asked questions
Can a stock 4Runner or Tacoma run this trail?
No. The minimum here is a modified 4WD with skid plates and rock sliders. Stock rigs will get torn up on the exposed granite ledges and loose rock shelves climbing to 5,100 ft — underbody damage is a real risk without armor.
When does the Mount Pilchuck Mining Road typically open and close each year?
Best window is May through October. Snow lingers well into spring at elevation, and the upper sections can close without warning from late October onward — check Washington State Parks conditions before you go, especially early and late season.
Do I need a permit or Discover Pass to run this trail?
Yes, a Washington State Discover Pass is required — it covers day use on state park land. No additional trail permit is needed, but have it displayed on your dash. Fines for no pass are common in Washington State Parks.
What's the hardest section and what should I actually expect?
The upper granite boulder fields are where it gets serious — large exposed rock shelves, off-camber moves, and loose debris with minimal recovery room. Line selection matters more than power here; one bad read and you're high-centered on granite with no easy tow point nearby.
How far is the nearest gas from the trailhead, and is there any camping along the route?
Granite Falls is your last fuel stop, roughly 15-20 miles from the trailhead — fill up before you head out. There's no designated dispersed camping on this route; it's a half-day out-and-back, not an overnight trail.
