Thorp Mountain via Knox Creek — Friday, Jul. 11, 2025

Snoqualmie Region > Salmon La Sac/Teanaway

Beautiful day for a hike with views! And the wildflowers were blooming all along the trail.  A few pesky mosquitos in the shade.

To get to the trail:  French Cabin Road was not signed nor numbered (FR4308); it was about 13 miles from the Roslyn roundabout.  The branch road to Knox Creek off of 4308 was unsigned as well, and full of huge potholes and rocks, difficult in our Prius.  A high clearance vehicle would be a better bet!

The trailhead is unsigned but visible from the road.  The first mile is very brushy, and has steep areas with lots of loose gravel and dirt.  Our poles were very useful for the way back down.  The upper trail is in good shape.
